    A PILOT STUDY OF PREOPERATIVE AND POSTOPERATIVE CHEMOTHERAPY IN PATIENTS WITH OPERABLE GASTRIC CANCER: AUSTRALASIAN GASTROINTESTINAL TRIALS GROUP STUDY 9601

    ANZ JOURNAL OF SURGERY, Issue 4 2007
    Michael Findlay
    Background: With poor cure rates in gastric cancer using surgery alone, the safety, efficacy and feasibility of preoperative and postoperative chemotherapy was investigated. Methods: Patients with advanced but operable gastric or cardio-oesophageal adenocarcinoma were staged using endoscopy, computed tomography scan and laparoscopy. If considered potentially resectable, they received chemotherapy (epirubicin, cisplatin and 5-fluorouracil) for 9 weeks before and after surgery. Results: Of 59 participants entered, two were found to have metastatic disease and were excluded from the analysis. Of the participants, 10 were women and 47 men; their median age was 58 years (range 27,83 years) and median performance status 0 (range 0,1). Two of the 57 participants commencing chemotherapy did not undergo surgery (one sudden death, one new liver metastases). Grade 3 and 4 preoperative and postoperative toxicity rates were, respectively, neutropenia 22 and 18%, emesis 12 and 14% and other non-haematological toxicity <10 and <10%. Of the 55 who underwent surgery, 40 had apparently curative resections (clear or positive microscopic margins), 2 died after surgery (anastomotic leak, sepsis) and 16 had postoperative complications. Of these, 27 participants commenced postoperative chemotherapy and 21 completed it. Median progression-free survival and overall survival were 19.6 and 22 months, respectively. Conclusion: Epirubicin, cisplatin and protracted venous infusion of 5-fluorouracil chemotherapy was well-tolerated in the preoperative setting and did not appear to increase complication rates of surgery for advanced and operable stomach cancer. These findings demonstrate the feasibility of this strategy in the Australasian clinical setting and are in keeping with the results of a recently reported randomized trial, which demonstrated a significant survival advantage using this chemotherapy regimen.

    A Percutaneous Approach to Eyebrow Lift: The Salvadorean Option

    DERMATOLOGIC SURGERY, Issue 8 2003
    Enrique Hernandez-Perez MD
    Background Surgical eyebrow lift can result in a number of complications. A nonsurgical simple method of lifting the brow is presented. Objective To raise the eyebrows using a simple, quick, and noninvasive approach. Methods Twenty-nine patients, 27 women and 2 men, whose ages varied from 24 to 56 years (mean of 32 years) were included in the study. Preoperative and postoperative photographs were taken. In two patients, brow suspension was performed at the time of blepharoplasty. Informed consent was signed by all of the patients. For measuring the degree of satisfaction of the patients, we gave to them a sheet grading it from one to three (with one being the least satisfactory). Local anesthesia (1% lidocaine, 1:400,000 epinephrine), a conveniently sized Keith needle, and prolene 3/0 sutures were used. Results Satisfying results were obtained in all cases. The only problem encountered in two patients was temporary edema, and it settled in a few days. Conclusion This is a very simple, quick, and noncomplicated method of raising the eyebrows. It can be repeated, revised easily, or combined with other modalities, such as peels, topical tretinoin, oral isotretinoin, fat injection, Goretex, and Botox as part of a facial rejuvenation program.

    The value of frozen section in intraoperative surgical management of thyroid follicular carcinoma,

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 7 2003
    Danijel Do, en MD
    Abstract Background. Preoperative and intraoperative diagnosis of follicular carcinoma (FC), resulting in one-stage surgical treatment of follicular thyroid tumors, is an important issue in thyroid surgery. Methods. In the 10-year period there were 4158 operations performed on thyroid gland. There were 1559 patients with follicular tumors, 70 (4.4%) of them having FC. We analyzed the groups of patients with FC determined on frozen section (FS) and permanent section (PS) according to duration of clinical symptoms, ultrasound (US) examination, tumor size, patient gender and age, intensity of invasion, localization, and multiple or solitary occurrence of tumor. Results. FC was diagnosed in 39 (55.7%) patients on frozen section (FS). Among the encapsulated (minimal invasion) carcinomas, the FS was accurate in 19 of 33 (57.6%) FC and in 5 of 15 (27.8%) Hürthle cell carcinomas (HCC); among extensively invasive carcinoma in 11 of 14 (78.6%) FC and in 4 of 5 (80.0%) HCC. FC was significantly more common in men (p < .001) and in the right lobe (p < .05). We did not find statistically significant differences concerning duration of symptoms, US examination, tumor size, patient age, and multiple or solitary occurrence of the tumor between the patients with FC diagnosed on FS and the patients with FC diagnosed on PS. Conclusions. The intraoperative diagnosis of FC is difficult. Although the percentage of false-negative results was relatively high (44.3%), there were no false-positive results. This means that the second operation was avoided in 55.7% of the patients, and no unnecessary thyroidectomies were performed. FS biopsy is an important method in surgery of follicular tumors. Improved technical support and the ability to analyze a greater number of slides will increase the accuracy of the method. © 2003 Wiley Periodicals, Inc. Head Neck 25: 521,528, 2003 [source]


    Diagnostic evaluation of cystic pancreatic lesions

    HPB, Issue 1 2008
    B. C. VISSER
    Abstract Background. Cystic pancreatic neoplasms (CPNs) present a unique challenge in preoperative diagnosis. We investigated the accuracy of diagnostic methods for CPN. Material and methods. This retrospective cases series includes 70 patients who underwent surgery at a university hospital for presumed CPNs between 1997 and 2003, and for whom a definitive diagnosis was established. Variables examined included symptoms, preoperative work-up (including endoscopic retrograde cholangiopancreatography (ERCP) in 22 cases and endoscopic ultrasound (EUS) in 12), and operative and pathological findings. Preoperative computed tomography (CT) and magnetic resonance imaging (MRI) scans (n=50 patients; CT=48; MRI=13) were independently reviewed by two blinded GI radiologists. Results. The final histopathologic diagnoses were mucinous cystic neoplasm (n=13), mucinous cystadenocarcinoma (10), serous cystadenoma (11), IPMN (14), simple cyst (3), cystic neuroendocrine tumor (5), pseudocyst (4), and other (10). Overall, 25 of 70 were malignant (37%), 21 premalignant (30%), and 24 benign (34%). The attending surgeon's preoperative diagnosis was correct in 31% of cases, incorrect in 29%, non-specific "cystic tumor" in 27%, and "pseuodcyst vs. neoplasm" in 11%. Eight had been previously managed as pseudocysts, and 3 pseudocysts were excised as presumed CPN. In review of the CT and MRI, a multivariate analysis of the morphologic features did not identify predictors of specific pathologic diagnoses. Both radiologists were accurate with their preferred (no. 1) diagnosis in <50% of cases. MRI demonstrated no additional utility beyond CT. Conclusions. The diagnosis of CPN remains challenging. Cross-sectional imaging methods do not reliably give an accurate preoperative diagnosis. Surgeons should continue to err on the side of resection. [source]


    Robotic-assisted laparoscopic radical prostatectomy: Learning curve of first 100 cases

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 7 2010
    Yen Chuan Ou
    Objective: Robotic-assisted laparoscopic radical prostatectomy (RALP) is gaining popularity for treating localized prostate cancer. We aimed to analyze the learning curve of a single surgeon using RALP in Taiwan. Methods: Medical records of 100 consecutive patients who underwent RALP were retrospectively reviewed. Preoperative, perioperative and postoperative parameters between patients in the first 30 cases (Group I), the second 30 cases (Group II) and cases 61,100 (Group III) undergoing RALP were analyzed. Results: Console time was shorter and blood loss was reduced in Groups II and III compared with Group I. Significant differences were found in vesicourethral anastomosis time (46.38 min for Group I vs 31.0 min for Group II vs 27 min for Group III, P < 0.01). Postoperative stay became statistically significantly shorter, from 7.33 days for Group I to 3.93 days for Group II to 3.0 days for Group III. Positive surgical margin of pT2 was reduced (13.3% for Group I, 7.1% for Group II and 0% for Group III) but not of pT3 (86.7% for Group I, 75% for Group II and 62.9% for Group III). Continence rate at 3 months was higher in Groups II (95%) and III (96.6%) than in Group 1 (76.7%, P < 0.05). Conclusions: For every 30 cases of RALP, vesicourethral anastomosis time and postoperative stay were significantly shorter. However, the incidence of surgical margin in pT3 prostate cancer was not significantly reduced. A learning curve of more than 100 cases is required to decrease the positive surgical margin in pT3 tumors. [source]


    Mitral Valve Replacements in Redo Patients with Previous Mitral Valve Procedures: Mid-Term Results and Risk Factors for Survival

    JOURNAL OF CARDIAC SURGERY, Issue 5 2008
    Tankut Hakki Akay M.D.
    Patients and Methods: Between September 1989 and December 2003, 62 redo patients have undergone mitral valve replacements due to subsequent mitral valve problems. Preoperative, operative, and postoperative data were analyzed retrospectively and evaluated for risk factors affecting hospital mortality, mid- and long-term survival. Results: The hospital mortality was 6.4%. The one-, five-, and 10-year actuarial survival rates were 94%± 2%, 89%± 6%, and 81 ± 9%. New York Heart Association (NYHA) functional class IV, low left ventricular ejection fraction (<35%), increased left ventricular end-diastolic diameter (LVEDD) > 50 mm, female gender, pulmonary edema, and urgent operations were found to be risk factors in short-term survival. NYHA functional class IV, low left ventricular ejection fraction, increased LVEDD, and increased left atrial diameter (LA > 60 mm) were risk factors in mid-term survival. Conclusion: Redo mitral valve surgery with mechanical prosthesis offers encouraging short- and mid-term survival. NYHA functional class IV, low left ventricular ejection fraction, and increased left ventricular diameters were especially associated with increased short- and mid-term mortality. Earlier surgical management before the development of severe heart failure and myocardial dysfunction would improve the results of redo mitral valve surgery. [source]


    Determinants of Incomplete Left Ventricular Mass Regression Following Aortic Valve Replacement for Aortic Stenosis

    JOURNAL OF CARDIAC SURGERY, Issue 4 2005
    Naoji Hanayama M.D.
    In this prospective study, we identified the predictors of Abn-LVMI. Methods: Between 1990 and 2000, 529 patients undergoing AVR for AS had clinical and hemodynamic data collected prospectively. Preoperative and annual postoperative transthoracic echos were employed to assess left ventricular mass index (LVMI) and hemodynamics. Abn-LVMI was defined as the 75th percentile of the lowest postoperative LVMI (>128 mg/m2, n = 133). All other patients were included in the normal regression group (N-LVMI). Univariate and multivariable logistic regression analyses were used to determine the predictors of Abn-LVMI. Results: Preoperative hypertension, diabetes, coronary disease, valve size, mean postoperative gradients, effective orifice area, and patient-prosthesis mismatch (PPM, indexed EOA <0.60 cm2/m2) did not predict Abn-LVMI. By logistic regression the most important positive predictor of Abn-LVMI was the extent of preoperative LVMI, with an odds ratio of 37.5 (p < 0.0001). Survival (93.4 ± 1.8% vs 94.8 ± 2.3%, p = 0.90) and freedom from NYHA III,IV (75.0 ± 3.7% vs 76.6 ± 5.3%, p = 0.60) were similar for both groups at 7 years. Conclusions: Measures of valve hemodynamics were not important predictors of incomplete regression of hypertrophy. The extent of preoperative hypertrophy was the most important predictor, suggesting that earlier surgical intervention may reduce the extent of hypertrophy postoperatively. Furthermore, the significance of LV hypertrophy to long-term survival must be reassessed, in the absence of scientific evidence. [source]


    Atrial Size Reduction as a Predictor of the Success of Radiofrequency Maze Procedure for Chronic Atrial Fibrillation in Patients Undergoing Concomitant Valvular Surgery

    JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 8 2001
    MIEN-CHENG CHEN M.D.
    Radiofrequency Maze Procedure and Atrial Size.Introduction: Previous studies showed that the surgical maze procedure can restore sinus rhythm and atrial transport function in patients with chronic atrial fibrillation (AF). However, no previous studies discussed the association of atrial size reduction and the success of sinus conversion by the radiofrequency (RF) maze procedure for chronic AF. Methods and Results: A total of 119 chronic AF patients undergoing valvular operations were included in this study. Sixty-one patients received RF and cryoablation to create lesions in both atria to simulate the surgical maze II or III procedure (RF maze II or RF maze III; 13 patients, group 1) or a modified maze pattern (RF maze "IV"; 48 patients, group 2). The other 58 patients who underwent valvular operations alone without the maze procedure served as control (group 3). At 3-month follow-up after operation, sinus rhythm was restored in 73%, 81%, and 11% of patients in groups 1, 2 and 3, respectively. Preoperative left and right atrial sizes were not statistically significant predictors of sinus conversion by the RF maze procedure. However, as a result of postoperative reduction of atrial sizes, postoperative left atrial diameter was significantly smaller in patients who had sinus conversion by the RF maze procedure than in patients who did not regain sinus rhythm (45.0 ± 7.0 mm vs 51.0 ± 8.0 mm; P = 0.03). Postoperative right atrial area of patients who had sinus conversion by the RF maze procedure also was significantly smaller than that of patients who did not regain sinus rhythm (18.1 ± 4.4 cm2 vs 28.5 ± 8.2 cm2; P = 0.008). Conclusion: Atrial size reduction appears to predict the success of sinus conversion with the RF maze procedure used in conjunction with valvular surgery. [source]


    Reasons for creation of permanent ileostomy for the management of idiopathic chronic constipation

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 8 2004
    AM EL-TAWIL
    Abstract The aim of the present study was to examine the reasons for initiation of end ileostomy for management of intractable constipation over the last 35 years. A total of 62 patients with intractable constipation, on whom an end ileostomy was created during the period from 1966 to 2001, were recorded. The incidence of initiating a terminal ileostomy as a further surgical intervention to the total number of managed patients in examined studies varied from 2 to 25%. Preoperative unevaluated anal and rectal abnormalities formed the highest proportion compared with other reasons (65%, 40/62). A better understanding of the functional colonic and anorectal abnormalities may facilitate changes in surgical therapy. [source]


    Prolonged activated partial thromboplastin time in thromboprophylaxis with unfractionated heparin in patients undergoing cesarean section

    JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2010
    Shigeki Matsubara
    Abstract Aim:, Hemorrhage is an important complication of heparin-thromboprophylaxis after surgery. We attempted to clarify the incidence rate of prolonged activated partial thromboplastin time (APTT), representative of hemorrhagic tendency, in Japanese women who received thromboprophylaxis with unfractionated subcutaneous heparin administration after cesarean section (CS). We also determined factors which affected postoperative APTT. Methods:, We studied 280 women who were administered thromboprophylaxis with unfractionated subcutaneous heparin 5000 IU two times per day after CS. Postoperative APTT under heparin was measured and the incidence of its prolongation was determined. Preoperative APTT, blood loss during surgery, postoperative hematocrit, postoperative serum total protein level, and postpartum body weight were measured, and their correlation with postoperative APTT was determined. Results:, Preoperative and postoperative APTT values were 28.3 (26.7,30.3) and 33.8 (31.0,37.5) seconds for median (interquartile range), respectively. Overall, 7.1% of patients showed ,45 s postoperative APTT. Two patients (0.7%) showed ,60 s APTT, one of whom suffered subcutaneous hemorrhage around the abdominal incision with complete healing. There were no other hemorrhagic complications. Preoperative APTT positively, and postpartum body weight inversely, correlated with postoperative APTT. The amount of blood loss, postoperative hematocrit, and postoperative serum total protein level did not correlate with postoperative APTT. No discernible deep vein thrombosis or pulmonary embolism occurred. Conclusion:, Although 7.1% of women under heparin-thromboprophylaxis showed a prolonged APTT that was 150% of the preoperative APTT, serious side effects were not observed. Subcutaneous administration of unfractionated heparin, if checking APTT prolongation 1 day after surgery, may be safe method of thromboprophylaxis after CS. [source]


    Should diagnostic laparoscopy be performed initially or not, during infertility management of primary and secondary infertile women?

    JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2009
    A cross-sectional study
    Abstract Objective:, The debate about the timing of diagnostic laparoscopy in unexplained infertile women has been investigated in this prospective study. Study design:, A total of 328 infertile women who underwent diagnostic laparoscopy for investigation of infertility at any stage of their infertility management from April 2001 to April 2003 were investigated. When the study group was resized according to the inclusion criteria 191 unexplained infertile patients were included. Preoperative and postoperative treatment strategies were compared. The correlation between hysterosalpingography and laparoscopy findings was identified. The results were evaluated using SPSS version 10.0 for Windows. Results:, A total of 106 patients were primary and 85 were secondary infertile. The mean ages of primary and secondary infertile patients were 27 ± 5 and 29 ± 5, respectively. Sixty percent of primary and 69% of secondary infertile patients had pelvic pathologies. Treatment strategies of 29 (43%) primary infertile and 27 (49%) secondary infertile patients with infertility-related risk factors changed after diagnostic laparoscopy. Conclusion:, Diagnostic laparoscopy in preparation for operative procedures (especially for secondary infertile women) should be performed initially in all unexplained infertile patients with or without risk factors related to pelvic pathologies.

    Effect of oral diacerein (DAR) in an experimental hip chondrolysis model

    JOURNAL OF ORTHOPAEDIC RESEARCH, Issue 6 2006
    Humberto Ken Kitadai
    Abstract We aimed to reproduce the articular cartilage structural changes in a joint exposed to a metallic implant as in the adolescent pinned hip with persistent joint penetration and secondly, to test the effect of an interleukin inhibitor, diacerein (DAR) in the ensuing articular cartilage lesion. Twenty immature beagles were submitted to a surgical K-wire implantation in the hip with the material left in the joint space for 6 months. Twelve animals were sacrificed for histological and biochemical tests. Eight animals were sacrificed at 10 months (half of them treated with DAR) and analyzed by scanning electron microscopy (SEM) and biochemistry of the articular cartilage. Preoperative and monthly C3 and C4 complement and immunoglobulins serum levels were determined. The histological and the electrophoretic profile changes were significative at 6 months. At 10 months the migration profile (CaCl2) recovered to normal levels in the operated hip and the SEM scores for the acetabulum were similar to the non operated control hip after treatment. The serum level of IgA was elevated at the 4th and 6th month postoperatively. The persistence of a metallic implant resulted in degenerative changes parallel to that described for hip chondrolysis as a complication of in-situ pinning; and the cartilage lesion improved with DAR treatment. © 2006 Orthopaedic Research Society.

    Characteristics and management of splenic artery aneurysms in adult living donor liver transplant recipients

    LIVER TRANSPLANTATION, Issue 11 2009
    Deok-Bog Moon
    Splenic artery aneurysms (SAAs), occurring in 7% to 17% of patients with cirrhosis, often result in catastrophic rupture after liver transplantation. We had experienced 3 cases of ruptured SAAs after adult living donor liver transplantation (LDLT), and we then performed this study to find risk factors for coexisting SAAs in liver transplant candidates with cirrhosis and to propose ideal approaches for them. Preoperative and postoperative computed tomography angiograms and axial views were reviewed for 310 adult LDLT recipients who had cirrhosis from January 2004 to August 2005. The recorded variables were the preoperative diagnosis, the presence of SAA and its characteristics, the splenic artery (SA) diameter, and the presence and size of portosystemic collaterals. Devastating SAA rupture accompanied by hypovolemic shock occurred on postoperative days 6, 82, and 8, respectively, and it was treated emergently by embolization in cases 1 and 2 and by splenectomy in case 3. Cases 1 and 3 recovered well, but case 2 died of an unrelated cause with a long hospital stay. The incidence of SAA during the study period was 14.2% (44/310), and the size was 16.6 ± 5.7 mm. Most SAAs were single (70.6%, 31/44) and were located in the distal one-third of the SA (82.4%, 36/44). Large portosystemic collaterals demonstrating longstanding severe portal hypertension were significantly correlated with the occurrence of SAAs. Nine patients with SAAs were preventively treated by proximal ligation (n = 4) intraoperatively and by embolization (n = 5) 1 day before or after LDLT. No patient showed severe postembolization syndrome. In conclusion, a careful preoperative evaluation of SAAs by high-resolution 3-dimensional computed tomography in liver transplant candidates, especially in those showing large portosystemic collaterals, is merited. Preventive treatment should be encouraged regardless of the size in order to avoid severe morbidity and mortality related to SAA rupture, and methods such as radiological and surgical interventions need to be individualized according to the location and number of SAAs.

    Childhood cirrhosis, hepatopulmonary syndrome and liver transplantation

    PEDIATRIC TRANSPLANTATION, Issue 3 2008
    Gokhan Tumgor
    Abstract:, Objectives:, The hepatopulmonary syndrome (HPS) is characterized as a triad: liver disease, intrapulmonary vascular dilatatiton, and arterial hypoxemia. The aim of this study is to analyze outcome of children with HPS in liver transplant era. Methods:, Between September 1996 and November 2006, 172 cirrhotic patients (median age 5 years; range 0.2,22 years, M/F; 97/75) were followed at Ege University Pediatric Gastroenterology, Hepatology and Nutrition Unit. All patients were evaluated by chest radiography, arterial blood gas analysis, and alveolar-arterial oxygen tension difference, contrast echocardiography (CEE) after and before the liver transplantation. Results:, HPS was diagnosed in 33 patients (19%) by CEE. None of them had pulmonary hypertension. HPS was not found related to etiology of the liver disease. Portal hypertension was found related to the development of HPS (75.7% in patients with HPS and 54.6% in others, p = 0.02). 17 of 33 patients with HPS underwent liver transplantation. Preoperative and postoperative period of these patients was uneventful. Patients were extubated in the operating room except for two. Median follow up of transplanted children was 1.9 year (range; 0.75,10 years). Arterial blood gas analysis and CEE positivity regressed in all of them by postoperative 6th month. Conclusions:, HPS is a serious and important complication of cirrhotic children that leads to tissue hypoxia and central cyanosis. HPS seems reversible after liver transplantation in all patients.

    Impact of Aspirin Intolerance on Outcomes of Sinus Surgery,

    THE LARYNGOSCOPE, Issue 5 2007
    Jamie L. Robinson MD
    Abstract Objectives: To compare objective and quality of life (QOL) outcomes after endoscopic sinus surgery (ESS) in aspirin (ASA)-tolerant patients and ASA-intolerant patients over intermediate and long-term follow-up. Study Design: Prospective analysis of a cohort of patients with chronic rhinosinusitis. Methods: Preoperative computed tomography (CT), pre- and postoperative endoscopy, and two validated disease specific QOL instruments, the Rhinosinusitis Disability Index (RSDI) and Chronic Sinusitis Survey (CSS), were collected. Differences in the proportions of patients who improved were analyzed using Pearson's chi-square and Fisher's exact test. Results: Nineteen ASA-intolerant patients and 104 ASA-tolerant patients were followed for a mean of 17.7 months. Patients with ASA intolerance had significantly worse preoperative CT (P < .0001) and endoscopy scores (P < .0001). After ESS, 57% to 74% of patients improved on endoscopy scores, 63% to 71% improved on the RSDI, and 58% to 73% improved on the CSS; improvement did not significantly differ by ASA status. Conclusions: Similar proportions of ASA-tolerant and ASA-intolerant patients showed improvement on endoscopy and QOL measures after ESS. [source]


    Preoperative versus Postoperative Role of Vestibular-Evoked Myogenic Potentials in Cerebellopontine Angle Tumor,

    THE LARYNGOSCOPE, Issue 2 2002
    Cheng-Wei Chen MD
    Abstract Objective/Hypothesis Vestibular-evoked myogenic potential (VEMP) examination was performed on patients with a cerebellopontine angle (CPA) tumor to evaluate its clinical role. Methods Patients with a CPA tumor were subjected to caloric test and VEMP examination. Follow-up study was performed 1 year after the surgery. Results Six (69%) of the 9 tumors did not exhibit either caloric response or VEMP on the lesioned side. Three patients received tumor excision and all tumors involved both the superior and inferior vestibular nerves. Two (22%) of the 9 tumors had normal caloric responses but no VEMP. One underwent surgical excision, and the tumor originated from the inferior vestibular nerve. In the follow-up study, only 1 patient with epidermoid cyst presented complete recovery of caloric response and VEMP, whereas in the other 3 patients with vestibular schwannoma, the responses were all absent persistently. Conclusion Before surgery, VEMP test can be used to predict the nerve of origin and to formulate the best surgical approach. After surgery, VEMP test can be used to define the nature of the tumor (compressing or infiltrating the nerve) and disclose the residual function of the inferior vestibular nerve. [source]


    Fascia Augmentation of the Vocal Fold: Graft Yield in the Canine and Preliminary Clinical Experience,

    THE LARYNGOSCOPE, Issue 5 2001
    Sanford G. Duke MD
    Abstract Introduction Glottal insufficiency resulting from vocal fold bowing, hypomobility, or scar is frequently treated by injection augmentation. Injection augmentation with fat, collagen, gel foam, polytef, and recently, fascia lata has been previously reported. Variable graft yield and poor host-tissue tolerance have motivated the continued search for an ideal graft substance. Study Design A prospective trial of autologous fascia augmentation of the vocal cord in the human and in an animal model. Methods Autologous fascia injection augmentation (AFIA) was evaluated in 8 canines and 40 patients at our institution between 1998 and 2000. The animal study compared graft yield from AFIA with autologous fat yield. The outcome measure was graft yield calculated from histological examination of larynges 12 weeks after injection augmentation. Clinical trial outcome measures included symptom surveys, acoustical voice analyses, and subjective voice assessments. Mean follow-up was 9 months. Results In the canine larynx, the mean graft yield for AFIA was 33% (range, 5%,84%) compared with autologous lipoinjection (47%; range, 7%,96%;P = .57). Subjective improvement in vocal quality was reported by 95% of patients (38 of 40) after AFIA. Preoperative and postoperative voice analysis data were obtained from 26 patients. Subjective voice rating demonstrated a significant improvement after AFIA (P <.0001). Acoustical parameters of jitter, shimmer, noise-to-harmonic ratio, phonatory range, and degree unvoiced improved significantly (P <.05) in all patients after fascia augmentation. Conclusions Based on the animal study, we concluded that graft yields are excellent but variable for AFIA. The result is similar in variability and overall yield to autologous lipoinjection. Subjective and objective analyses of voice outcomes after AFIA are universally improved. Fascia appears to be an excellent alternative to lipoinjection in properly selected cases of glottic insufficiency. [source]


    Twenty-Year Experience With Heart Transplantation for Infants and Children With Restrictive Cardiomyopathy: 1986,2006

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2008
    A. J. Bograd
    Idiopathic restrictive cardiomyopathy (RCM) is a rare cardiomyopathy in children notable for severe diastolic dysfunction and progressive elevation of pulmonary vascular resistance (PVR). Traditionally, those with pulmonary vascular resistance indices (PVRI) >6 W.U. × m2 have been precluded from heart transplantation (HTX). The clinical course of all patients transplanted for RCM between 1986 and 2006 were reviewed. Preoperative, intraoperative and postoperative variables were evaluated. A total of 23 patients underwent HTX for RCM, with a mean age of 8.8 ± 5.6 years and a mean time from listing to HTX of 43 ± 60 days. Preoperative and postoperative (114 ± 40 days) PVRI were 5.9 ± 4.4 and 2.9 ± 1.5 W.U. × m2, respectively. At time of most recent follow-up (mean = 5.7 ± 4.6 years), the mean PVRI was 2.0 ± 1.0 W.U. × m2. Increasing preoperative mean pulmonary artery pressure (PA) pressure (p = 0.04) and PVRI > 6 W.U. × m2 (,2= 7.4, p < 0.01) were associated with the requirement of ECMO postoperatively. Neither PVRI nor mean PA pressure was associated with posttransplant mortality; 30-day and 1-year actuarial survivals were 96% and 86%, respectively. Five of the seven patients with preoperative PVRI > 6 W.U. × m2 survived the first postoperative year. We report excellent survival for patients undergoing HTX for RCM despite the high proportion of high-risk patients. [source]

    Saleh M. Abbas
    Background: Idiopathic faecal incontinence is a common debilitating problem; the results of surgical treatment are variable with only a small proportion of patients achieving full continence. Objectives: The aim of this study was to evaluate the long-term outcome of postanal repair in idiopathic faecal incontinence. Patients and methods: Patients who had postanal repair in Auckland between 1994 and 2001 were identified and mailed faecal incontinence severity index (FISI) and faecal incontinence quality of life (FIQOL) questionnaires. Preoperative and postoperative incontinence scores were compared and postoperative quality of life scores were calculated. Results: Forty-seven of the 66 patients who had undergone postanal repair from 1994 to 2001 completed the FIQOL questionnaire. FISI scores were complete on 44 patients. Comparison of preoperative and postoperative FISI scores revealed an improvement with mean scores of 34 and 23, respectively (P = 0.0001). Thirty (68%) patients had improved, including four who were fully continent. Fourteen patients were the same or worse. Conclusions: Postanal repair provides lasting benefit for the majority of patients with faecal incontinence. [source]


    Relationship between elevated preoperative troponin T and adverse outcomes following cardiac surgery

    ANZ JOURNAL OF SURGERY, Issue 1-2 2003
    William J. Lyon
    Background: The prognostic value of troponin T (TnT) has been demonstrated in patients following a myocardial infarction. There are limited data regarding the prognostic utility of preoperative TnT in patients undergoing cardiac surgery. The aim of the present study was to determine if elevated preoperative TnT is a predictor of more complex recovery outcomes in the cardiac surgical setting. Methods: A single preoperative TnT measurement was assessed in 696 patients undergoing isolated coronary artery bypass graft surgery. Elevated preoperative TnT levels were classified as ,0.2 ng/mL. Preoperative, intraoperative, intensive care and postoperative events were prospectively recorded for all patients, and retrospectively reviewed for the present study. Results: Elevated preoperative TnT levels were detected in 10% (71/696) of patients. Compared to patients with normal TnT levels, elevated preoperative TnT increased the risk of mortality at 30 days (7%vs 1%, P = 0.004, odds ratio (OR) = 6.7) and 2 years (14%vs 3%, P < 0.001, OR = 5.0), and resulted in prolonged intensive care unit (ICU) stays (P < 0.001) and longer postoperative hospitalization (P < 0.001). Elevated preoperative TnT was also associated with an increased need for perioperative and postoperative cardiovascular support, early ischaemic change and postoperative congestive cardiac failure. In multivariate analyses preoperative TnT was a significant independent predictor of 30-day and 2-year mortality, and duration of ICU stay. Conclusions: Elevated preoperative TnT highlights a subgroup of cardiac surgical patients who are more likely to have a post­operative course with increased morbidity and mortality. [source]


    Beneficial Effect of Preventative Intra-Aortic Balloon Pumping in High-Risk Patients Undergoing First-Time Coronary Artery Bypass Grafting,A Single Center Experience

    ARTIFICIAL ORGANS, Issue 8 2009
    Qingcheng Gong
    Abstract Although intra-aortic balloon pumping (IABP) has been used widely as a routine cardiac assist device for perioperative support in coronary artery bypass grafting (CABG), the optimal timing for high-risk patients undergoing first-time CABG using IABP is unknown. The purpose of this investigation is to compare preoperative and preventative IABP insertion with intraoperative or postoperative obligatory IABP insertion in high-risk patients undergoing first-time CABG. We reviewed our IABP patients' database from 2002 to 2007; there were 311 CABG patients who received IABP treatment perioperatively. Of 311 cases, 41 high-risk patients who had first-time on-pump or off-pump CABG (presenting with three or more of the following criteria: left ventricular ejection fraction less than 0.45, unstable angina, CABG combined with aneurysmectomy, or left main stenosis greater than 70%) entered the study. We compared perioperatively the clinical results of 20 patients who underwent preoperative IABP placement (Group 1) with 21 patients who had obligatory IABP placement intraoperatively or postoperatively during CABG (Group 2). There were no differences in preoperative risk factors, except left ventricular aneurysm resection, between the two groups. There were no differences in indications for high-risk patients between the two groups. The mean number of grafts was similar. There were no significant differences in the need for inotropes, or in cerebrovascular, gastrointestinal, renal, and infective complications postoperatively. There were no IABP-related complications in either group. Major adverse cardiac event (severe hypotension and/or shock, myocardial infarction, and severe hemodynamic instability) was higher in Group 2 (14 [66.4%] vs. 1 [5%], P < 0.0001) during surgery. The time of IABP pumping in Group 1 was shorter than in Group 2 (72.5 ± 28.9 h vs. 97.5 ± 47.7 h, P < 0.05). The duration of ventilation and intensive care unit stay in Group 1 was significantly shorter than in Group 2, respectively (22.0 ± 1.6 h vs. 39.6 ± 2.1 h, P < 0.01 and 58.0 ± 1.5 h vs. 98.5 ± 1.9 h, P < 0.005). There were no differences in mortality between the two groups (n = 1 in Group 1 and n = 3 in Group 2). Preoperative and preventative insertion of IABP can be performed safely in selected high-risk patients undergoing CABG, with results comparable to those in patients who received obligatory IABP intraoperatively and postoperatively. Therefore, earlier IABP support as part of surgical strategy may help to improve the outcome in high-risk first-time CABG patients. [source]


    Coronary Artery Bypass Grafting for Hemodialysis- Dependent Patients

    ARTIFICIAL ORGANS, Issue 4 2001
    Hitoshi Hirose
    Abstract: Patients with end-stage renal disease carry a risk of coronary atherosclerosis. This study was performed to evaluate the perioperative and remote data of coronary artery bypass grafting (CABG) in hemodialysis dependent patients. We retrospectively analyzed the results of isolated CABG performed at Shin-Tokyo Hospital between June 1, 1993 and May 31, 2000. Preoperative, perioperative, and follow-up data of the patients on hemodialysis (Group HD, n = 37) were collected and compared with those of control patients (Group C, n = 1,639). Group HD consisted of 26 males and 11 females with a mean age of 59.9 ± 8.1 years, and the mean number of bypasses was 2.5 ± 1.1. Group HD had a longer postoperative intubation time, ICU stay, and hospital stay than Group C. The postoperative major complication rate in Group HD (18.9%) was not significantly different from that in Group C (11.3%). However, the inhospital mortality rate in Group HD (5.4%) was higher than Group C (0.6%). At the mean follow-up of 2.4 years, the actuarial 3-year survival of Groups HD and C were 90.6% and 97.6%, respectively (p < 0.001), excluding hospital mortality. The actuarial 3-year cardiac event-free rates were 84.3% in Group HD and 88.8% in Group C, showing no difference. Patients on chronic hemodialysis carry a significant risk of prolonged inhospital care and hospital death. Once successful surgical revascularization was completed, their long-term cardiac events could be controlled as effectively. The increased distant death rates was probably associated with the nature of renal disease. [source]


    Single-port laparoscopic splenectomy: The first three cases

    ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 1 2010
    Y.K. You
    Abstract In the past two decades, laparoscopic surgery has replaced open surgery in most abdominal surgeries, including splenectomies for which it has become the standard. Single-port laparoscopic surgery is a newly emerging surgical technique that decreases postoperative scarring and parietal trauma. Herein we report on three cases of splenectomy in which single-port laparoscopic surgery technique was applied. Between October 2008 and January 2009, a 13-year-old male suffering from grade-III splenic trauma and two females, aged 33 and 61, respectively, and both diagnosed with immune thrombocytopenic purpura, underwent single-port laparoscopic splenectomies. Preoperative and postoperative management, including vaccination, was performed in a routine manner. A 3.5 cm transverse incision at the anterior axillary line at umbilicus level was used as a single-port entry point. The entire procedure took 195, 125 and 133 minutes, respectively. All patients recovered and were discharged without any complications. [source]


    Risk factors for portal venous thrombosis after splenectomy in patients with cirrhosis and portal hypertension

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 6 2010
    N. Kinjo
    Background: Portal venous thrombosis (PVT) is a potentially fatal complication following splenectomy. Its mechanisms and risk factors are poorly understood, especially in patients with cirrhosis and portal hypertension. This study investigated risk factors for PVT following splenectomy in such patients. Methods: All consecutive patients with cirrhosis who underwent splenectomy in Kyushu University Hospital between 1998 and 2004 were included in this retrospective study. They were divided into two groups based on the presence or absence of postoperative PVT. Preoperative and operative factors were compared, and the relationships between formation of PVT and its independent variables were analysed. In some cases, portal venous flow was measured before and after splenectomy using duplex Doppler ultrasonography. Results: PVT developed after surgery in 17 (24 per cent) of 70 patients studied. Multivariable analysis showed that increased splenic vein diameter and low white cell count were significant independent risk factors for PVT. Portal venous flow after splenectomy was greatly reduced in the PVT group, but not in patients without PVT. Conclusion: Large splenic vein diameter and low white cell count are independent risk factors for PVT after splenectomy in patients with cirrhosis and portal hypertension.

    Preoperative but not postoperative systemic inflammatory response correlates with survival in colorectal cancer,

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2007
    J. E. M. Crozier
    Background: The aim of the present study was to evaluate the relationship between the preoperative and postoperative systemic inflammatory response and survival in patients undergoing potentially curative resection for colorectal cancer. Methods: One hundred and eighty patients with colorectal cancer were studied. Circulating concentrations of C-reactive protein (CRP) were measured before surgery and in the immediate postoperative period. Results: The peak in CRP concentration occurred on day 2 (P < 0·001). During the course of the study 59 patients died, 30 from cancer and 29 from intercurrent disease. Day 2 CRP concentrations were dichotomized. In univariable analysis, advanced tumour node metastasis stage (P = 0·002), a raised preoperative CRP level (P < 0·001) and the presence of hypoalbuminaemia (P = 0·043) were associated with poorer cancer-specific survival. Conclusion: Preoperative but not postoperative CRP concentrations are associated with poor tumour-specific survival in patients undergoing potentially curative resection for colorectal cancer.

    Aneurysm-related mortality during late follow-up after endovascular aneurysm repair of infrarenal aorta

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2001
    S. R. Vallabhaneni
    Background: Aneurysm-related mortality (ARM) accounts for around 1·5 per cent of all deaths following open aneurysm repair. The incidence of ARM following endovascular aneurysm repair (EVAR) is unknown. The aim was to examine all causes of death, including ARM, during late follow-up after EVAR. ARM was defined as death resulting directly from rupture of the repaired aneurysm or another complication of the aneurysm, more than 30 days after repair, or death within 30 days of a secondary intervention undertaken solely to rectify a complication of repair. Methods: Preoperative and follow-up data on 2194 patients from 88 European centres were collected prospectively on to a database. Survival up to 48 months after EVAR was analysed by means of Kaplan,Meier survival analysis. The causes of death during this period were noted. Results: There were 161 deaths between 1 and 48 months after EVAR. The cumulative rate of secondary intervention for this cohort at 4 years was 33 per cent. The causes of death were: cardiac 28·6 per cent, malignancy 18·6 per cent, cerebrovascular 6·8 per cent, respiratory 3·1 per cent, renal 1·8 per cent, other 22·3 per cent and ARM 11·8 per cent. There were 19 deaths from aneurysm-related causes. Nine patients died following proven rupture of the aneurysm, three died from presumed rupture of the aneurysm and a further seven died following late conversion (three patients), graft sepsis (two) and secondary intervention (two). Sudden death of uncertain cause occurred in ten patients in whom rupture of AAA was a possibility. Conclusion: Non-aneurysm-related causes of death were comparable to those in published reports of survival after open repair. However, the proportion of aneurysm-related deaths (11·8 per cent) was appreciably higher than that reported after open repair. These results may reflect the learning curve experience of the teams involved in the study, but continued caution is advisable regarding expectations of outcome following EVAR. © 2001 British Journal of Surgery Society Ltd [source]


    Vitreoretinal surgery in Behçet's disease with severe ocular complications

    ACTA OPHTHALMOLOGICA, Issue 2 2001
    Yusuf Özertürk
    ABSTRACT. Purpose: To investigate effects of vitreoretinal surgery in Behçet's disease. Materials and Method: Vitreoretinal surgery was applied to 26 eyes of 21 patients with Behçet's disease. Preoperative and postoperative visual acuities, number and duration of attacks, anterior and posterior segment pathologies were evaluated. Results: The mean age of the patients was 33 years and female/male ratio was 6/15. The mean follow-up was 23 months. Visual acuity increased in 15 eyes (58%), did not change in 11 eyes (42%). In the postoperative period, there was a significant decrease in mean number of uveitis attacks compared to the preoperative period (p=0.001), as well as a significant decrease in the mean duration of uveitis attacks (p=0.001). In the postoperative follow-up, intravitreal haemorrhage in 2 eyes (8%), posterior subcapsular cataract in 5 eyes (19%) and corticonuclear cataract in 2 eyes (8%) were observed. Posterior capsular opacification (PCO) developed in 5 of 16 eyes (31%) having ECLE-IOL. CME continued in 3 eyes (12%). Conclusion: Vitreoretinal surgery has favourable effect on the visual and anatomic prognosis in Behçet's patients with severe ocular complications. [source]


    Suppression of the postoperative neutrophil leucocytosis following neoadjuvant chemoradiotherapy for rectal cancer and implications for surgical morbidity

    COLORECTAL DISEASE, Issue 6 2010
    S. F. Kerr
    Abstract Objective, The extent to which neoadjuvant chemoradiotherapy for rectal cancer influences postoperative morbidity is controversial. This study investigated whether this treatment suppresses the normal perioperative inflammatory response and explored the clinical implications. Method, Prospective databases were queried to identify 37 consecutive study patients undergoing definitive surgery following 5-FU/capecitabine-based chemoradiotherapy and 34 consecutive untreated control patients operated upon for rectal or rectosigmoid cancer. Preoperative (< 10 days) and postoperative (< 24 h) neutrophil counts, along with morbidity data, were confirmed retrospectively. Univariate and multivariate analyses assessed the apparent effect of chemoradiotherapy on change in neutrophil count. The latter's association with postoperative morbidity was then examined. Results, Sufficient data were available for 34 study and 27 control patients. Repeated-measures ANCOVA revealed significant differences between their perioperative neutrophil counts (P = 0.02). Of the other characteristics which differed between the groups, only age and tumour location were prognostically significant regarding perioperative change in neutrophil count. Accounting for relevant covariates, chemoradiotherapy was significantly associated with a suppressed perioperative neutrophil leucocytosis. Local postoperative complications affected 25 of 61 patients, who had lower perioperative neutrophil increases than their counterparts (P = 0.016). Conclusion, Chemoradiotherapy appears to suppress the perioperative inflammatory response, thereby increasing susceptibility to local postoperative complications. [source]


    Preoperative conditioning with oral carbohydrate loading and oral nutritional supplements can be combined with mechanical bowel preparation prior to elective colorectal resection

    COLORECTAL DISEASE, Issue 9 2008
    P. O. Hendry
    Abstract Objective, Preoperative conditioning with oral fluid and carbohydrate (CHO) loading allows the patient to undergo surgery in the fed state and is associated with reduced postoperative insulin resistance. Further benefit may accrue from oral nutritional supplements (ONS) to counteract the fasting associated with mechanical bowel preparation (MBP). In this study we assess the ability to prescribe, dispense and have patients comply with a protocol combining preoperative ONS and CHO/fluid loading during MBP. Method, One hundred and forty-seven patients undergoing elective left colonic or rectal resection were recruited to an Enhanced Recovery after Surgery (ERAS) programme. All patients were prescribed MBP (2 sachets Picolax). On the daytime prior to surgery, eligible patients were prescribed 2 × 200 ml of ONS (Fortijuice®, Nutricia) and in the evening 800 ml oral CHO/fluid loading (Preop®, Nutricia,). Patients were prescribed a further 400 ml of oral/CHO/fluid on the morning of surgery 2 h prior to induction of anaesthesia. Protocol compliance was audited prospectively. Results, One hundred and forty-seven patients received MBP. Twenty-three patients were ineligible for oral CHO/fluid loading [diabetes (n = 22), allergy to lemon flavoured drinks (n = 1)]. Fourteen patients did not receive the preoperative CHO drinks due to failure to prescribe (n = 8) or dispense (n = 6). One hundred and ten patients were dispensed the combined ONS and CHO/fluid loading regimen, compliance rates were 83% with ONS, 80% with CHO/fluid loading and 74% with both. Conclusion, Approximately 74% of patients undergoing MBP can comply with preoperative conditioning with ONS and CHO/fluid loading. Prescription and dispensing requires close attention to detail.

    Early Surgical Morbidity and Mortality in Adults with Congenital Heart Disease: The University of Michigan Experience

    CONGENITAL HEART DISEASE, Issue 2 2008
    Ginnie L. Abarbanell MD
    ABSTRACT Objectives., To review early surgical outcomes in a contemporary series of adults with congenital heart disease (CHD) undergoing cardiac operations at the University of Michigan, and to investigate possible preoperative and intraoperative risk factors for morbidity and mortality. Methods., A retrospective medical record review was performed for all patients ,18 years of age who underwent open heart operations by a pediatric cardiothoracic surgeon at the University of Michigan Congenital Heart Center between January 1, 1998 and December 31, 2004. Records from a cohort of pediatric patients ages 1,17 years were matched to a subset of the adult patients by surgical procedure and date of operation. Results., In total, 243 cardiac surgical operations were performed in 234 adult patients with CHD. Overall mortality was 4.7% (11/234). The incidence of major postoperative complications was 10% (23/234) with a 19% (45/23) minor complication rate. The most common postoperative complication was atrial arrhythmias in 10.8% (25/234). The presence of preoperative lung or liver disease, prolonged cardiopulmonary bypass and aortic cross clamp times, and postoperative elevated inotropic score and serum lactates were significant predictors of mortality in adults. There was no difference between the adult and pediatric cohorts in terms of mortality and morbidity. Conclusions., The postoperative course in adults following surgery for CHD is generally uncomplicated and early survival should be expected. Certain risk factors for increased mortality in this patient population may include preoperative presence of chronic lung or liver dysfunction, prolonged cardiopulmonary bypass and aortic cross-clamp times, and postoperative elevated inotropic score and serum lactate levels.
