Selected AbstractsShort-term symptom and quality-of-life comparison between laparoscopic Nissen and Toupet fundoplicationsDISEASES OF THE ESOPHAGUS, Issue 1 2009R. Radajewski SUMMARY Laparoscopic antireflux surgery is an established method of treatment of gastroesophageal reflux disease (GERD). This study evaluates the efficacy of Nissen versus Toupet fundoplication in alleviating the symptoms of GERD and compares the two techniques for the development of post-fundoplication symptoms and quality of life (QOL) at 12 months post-surgery. In this prospective consecutive cohort study, 94 patients presenting for laparoscopic antireflux surgery underwent either laparoscopic Nissen fundoplication (LN) (n = 51) from February 2002 to February 2004 or a laparoscopic Toupet fundoplication (LT) (n = 43) from March 2004 to March 2006, performed by a single surgeon (G. S. S.). Symptom assessment, a QOL scoring instrument, and dysphagia questionnaires were applied pre- and postoperatively. At 12 months post-surgery, patient satisfaction levels in both groups were high and similar (LT: 98%, LN: 90%; P = 0.21). The proportion of patients reporting improvement in their reflux symptoms was similar in both groups (LT: 95%, LN: 92%; P = 0.68), as were post-fundoplication symptoms (LT: 30%, LN: 37%; P = 0.52). Six patients in the Nissen group required dilatation for dysphagia compared with one in the Toupet group (LT: 2%, LN: 12%; P = 0.12). One patient in the Nissen group required conversion to Toupet for persistent dysphagia (P = 0.54). In this series, overall symptom improvement, QOL, and patient satisfaction were equivalent 12 months following laparoscopic Nissen or Toupet fundoplication. There was no difference in post-fundoplication symptoms between the two groups, although there was a trend toward a higher dilatation requirement and reoperation after Nissen fundoplication. [source] Oxford experience with neoadjuvant chemotherapy and surgical resection for esophageal adenocarcinomas and squamous cell tumorsDISEASES OF THE ESOPHAGUS, Issue 3 2008P. M. Safranek SUMMARY., The Medical Research Council trial for oesophageal cancer (OEO2) trial demonstrated a clear survival benefit from neoadjuvant chemotherapy in resectable esophageal carcinoma. Since February 2000 it has been our practice to offer this chemotherapy regime to patients with T2 and T3 or T1N1 tumors. We analyzed prospectively collected data of patients who received neoadjuvant chemotherapy prior to esophageal resection under the care of a single surgeon. Complications of treatment and overall outcomes were evaluated. A total of 194 patients had cisplatin and 5-fluorouracil prior to esophageal resection. Six patients (5.7%) had progressive disease and were inoperable (discovered in four at surgery). During chemotherapy one patient died and one perforated (operated immediately). Complications including severe neutropenia, coronary artery spasm, renal impairment and pulmonary edema led to the premature cessation of chemotherapy in 12 patients (6.2%). A total of 182 patients with a median age of 63 (range 30,80), 41 squamous and 141 adenocarcinomas underwent surgery. Operations were 91 left thoracoabdominal (50%), 45 radical transhiatal (25%), 40 Ivor-Lewis (22%) and six stage three (3%), and 78.6% had microscopically complete (R0) resections. Median survival was 28 months with 77.3% surviving for 1 year and 57.7% for 2 year. In hospital mortality was 5.5% and anastomotic leak rate 7.7%. A radical surgical approach to the primary tumor in combination with OEO2 neoadjuvant chemotherapy has led to a high R0 resection rate and good survival with acceptable morbidity and mortality. [source] Reconstruction with radial forearm flaps after ablative surgery for hypopharyngeal cancerHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 4 2003Joseph Scharpf MD Abstract Background. Patients afflicted with advanced hypopharyngeal cancer must contend with both potentially poor survival prognosis and a compromised quality of remaining life. After extensive ablative surgery, it is imperative to use a reliable, low morbidity reconstructive strategy that will allow for an expedient reconstitution of speech and swallowing. Methods. Retrospective review of the records of 28 patients who underwent pharyngoesophageal reconstruction with radial forearm free flaps (RFFF) between 1996 and 2001 by a single surgeon (RE). Analysis was confined to patients requiring complete tubulation of the RFFF. Perioperative mortality, morbidity, and functional evaluation based on the parameters of speech and swallowing were analyzed. Results. Completely tubulated RFFF were required in 25 patients. There was 100% RFFF survival with no perioperative mortalities. The median hospital stay was 8.0 days. All patients acquired a reconstitution of oral alimentation; median time to swallowing was 18.0 days. Fourteen of 16 patients (93%) were able to rely on TEP speech as their main modality of communication. Two patients (8%) had early fistulas develop, and 5 (20%) had late fistulas develop. Nine patients (36%) required mechanical dilatation; five of the nine patients required only one dilatation. Conclusion. Review of our experience has confirmed the reliability and excellent functional outcome associated with this flap. © 2003 Wiley Periodicals, Inc. Head Neck 25: 261,266, 2003 [source] Factors affecting outcome in liver resectionHPB, Issue 3 2005CEDRIC S. F. LORENZO Abstract Background. Studies demonstrate an inverse relationship between institution/surgeon procedural volumes and patient outcomes. Similar studies exist for liver resections, which recommend referral of patients for liver resections to ,high-volume' centers. These studies did not elucidate the factors that underlie such outcomes. We believe there exists a complex interaction of patient-related and perioperative factors that determine patient outcomes after liver resection. We sought to delineate these factors. Methods. Retrospective review of 114 liver resections by a single surgeon from 1993,2003: Records were reviewed for demographics; diagnosis; type/year of surgery; American Society of Anesthesiologists (ASA) score; preoperative albumin, creatinine, and bilirubin; operative time; intraoperative blood transfusions; epidural use; and intraoperative hypotension. Main outcome measurements were postoperative morbidities, mortalities and length of stay (LOS). Data were analyzed using a multivariate linear regression model (SPSS v10.1 statistical analysis program). Results. Primary indications for resections were hepatocellular carcinoma (HCC) (N=57), metastatic colorectal cancer (N=25), and benign disease (N=18). There were no intraoperative mortalities and 4 perioperative (30-day) mortalities (3.5%). Mortality occurred in patients with malignancies who were older than 50 years. Morbidity was higher in malignant (15.6%) versus benign (5.5%) disease. Complications included bile leak/stricture (N=6), liver insufficiency (N=3), postoperative bleeding (N=2), myocardial infarction (N=2), aspiration pneumonia (N=1), renal insufficiency (N=1), and cancer implantation into the wound (N=1). Average LOS for all resections was 8.6 days. Longer operative time (p=0.04), lower albumin (p<0.001), higher ASA score (p<0.001), no epidural use (p=0.04), and higher creatinine (p<0.001) all correlated positively with longer LOS. ASA score and creatinine were the strongest predictors of LOS. LOS was not affected by patient age, sex, diagnosis, presence of malignancy, intraoperative transfusion requirements, intraoperative hypotension, preoperative bilirubin, case volume per year or year of surgery. Conclusions. Liver resections can be performed with low mortality/morbidity and with acceptable LOS by an experienced liver surgeon. Outcome as measured by LOS is most influenced by patient comorbidities entering into surgery. Annual case volume did not influence LOS and had no impact on patient safety. Length of stay may not reflect surgeon/institution performance, as LOS is multifactorial and likely related to patient population, patient selection and increased high-risk cases with a surgeon's experience. [source] Preoperative determinants of common bile duct stones during laparoscopic cholecystectomyINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 11 2008A. J. Sheen Summary Introduction:, The aim of this study is to determine whether there are any clinical or biochemical predictors of common bile duct (CBD) stones in patients undergoing laparoscopic cholecystectomy. Methods:, A prospective database of nearly 1000 laparoscopic cholecystectomies performed under the care of a single surgeon with a standardised technique between 1999 and 2006, was analysed. Clinical presentation, ultrasound and immediate preoperative biochemical results as well as the operative cholangiogram findings were reviewed. Routine cholangiography was attempted in most patients and the primary outcome variable was the detection of bile duct stones. The data was analysed using chi-squared test for categorical variables. The significant variables on univariate analysis were further characterised to identify the independent predictors of bile duct stones using a logistic regression model (significance p < 0.05). Results:, A total of 757 of 988 patients (77%) underwent cholangiography. Male-to-female ratio was 1 : 3 with a median age of 54 years (range: 17,93). Ten per cent of patients had bile duct stones identified on cholangiography. On univariate analysis, jaundice (p = 0.019), cholangitis (p < 0.001), alanine transaminase > 100 (p = 0.024), alkaline phosphatase (ALP) > 350 (p < 0.001) and CBD > 10 mm (p = 0.01) were significant markers for predicting bile duct stones. Bilirubin > 30 (×2 normal) was found not to be significant (p = 0.145). On a logistic regression model, ALP > 350 and/or cholangitis were found to be independent predictive factors of CBD stones (odds ratio 6.1). Conclusions:, If a policy of routine intra-operative cholangiography is not adopted, a history of cholangitis or a raised ALP immediately preoperatively should lead to a high suspicion of CBD stones. [source] Robotic-assisted laparoscopic radical prostatectomy: Learning curve of first 100 casesINTERNATIONAL JOURNAL OF UROLOGY, Issue 7 2010Yen 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] Radical retropubic prostatectomy with running vesicourethral anastomosis and early catheter removal: Our experienceINTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2009Choichiro Ozu Objectives: To assess the outcomes of patients undergoing radical retropubic prostatectomy (RRP) with a running vesicourethral anastomosis and catheter removal on postoperative day 3 or 5. Methods: From February 2006 through December 2007, 55 patients underwent RRP at our institution. All procedures were performed by a single surgeon using a running suture for the vesicourethral anastomosis. A cystogram was carried out before catheter removal in all patients. The initial 23 of 55 patients (Group 1; n = 23) had the cystogram on postoperative day 5, the other 32 patients (Group 2; n = 32) had the cystogram on postoperative day 3. Removal of the catheter was only carried out if there was no anastomotic extravasation. Results: The success rate of catheter removal in group 1 and 2 was 100% and 96.9%, respectively. Overall continence rates were 83.3%, 87% and 90.7% at 24, 48 and 72 h after removal of the catheter, respectively. There was no significant difference in terms of continence rate between groups 1 and 2. None of the patients had acute urinary retention and/or anastomotic stricture after catheter removal. Conclusions: These findings suggest that an advanced running vesicourethral anastomosis during RRP is technically feasible, allowing safe early catheter removal in most patients. [source] Learning curve of hand-assisted retroperitoneoscopic nephrectomy in less-experienced laparoscopic surgeonsINTERNATIONAL JOURNAL OF UROLOGY, Issue 1 2005AKIHIRO KAWAUCHI Abstract Aim:, To evaluate the learning curve of hand-assisted retroperitoneoscopic nephrectomy (HALS) performed by less-experienced surgeons. Methods:, The operative records of 166 patients, including 103 with renal tumors and 63 with renal pelvic or ureteral tumors, who underwent HALS performed by 18 less-experienced urologists were reviewed. Results:, The insufflation time in the first four cases was significantly longer than that in the sixteenth and later cases. The insufflation time in cases 5,10 was 14,24 min longer than that in the cases 16 onward, although the differences were not significant. The estimated blood loss did not differ in each group of cases. The complication rate in early cases, in which the operators' experience was five cases or less, was 6% (4/71), while that in later cases was also 7% (7/95). In the analysis of the learning curve of a single surgeon who performed 57 procedures, the insufflation time in cases 1,5 was significantly longer than in cases 41,57. The insufflation times in cases 5,10 were 45 min longer than those in cases 41,57, although the difference was not significant. The estimated blood loss did not differ in each group of cases. Complications did not seem related to operation experience. Conclusion:, In HALS, 5,10 cases were necessary for less-experienced urologists to gain average operating skills for this procedure. It may be reasonable for less-experienced surgeons to begin standard laparoscopic procedures after experiencing 10 cases of the present procedure. [source] Sparing the larynx during gynecological laparoscopy: a randomized trial comparing the LMA SupremeÔ and the ETTACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2010W. ABDI Background: We designed a prospective randomized single-blind study to compare efficiency and post-operative upper airway morbidity when the laryngeal mask airway (LMA) SupremeÔ is used as an alternative to the endotracheal tube (ETT). Methods: One hundred and thirty-eight elective pelvic laparoscopic ASA I,II female patients were assigned to receive either the LMA Supreme® or the ETT for airway management. Balanced anesthesia and ventilation techniques were standardized to control end-tidal CO2 and BIS value in the range 4.5,5 kPa and 40,50, respectively, and to maintain adequate hemodynamic stability. A single surgeon blinded to the airway management technique performed all surgical procedures. The ventilation efficiency of each airway was evaluated. Anesthesia- and surgery-related times were calculated and anesthesia details were recorded. Post-operative pain and pharyngolaryngeal morbidity were measured in a blind fashion using a numerical rating scale (NRS) (0,100). Results: Surgery duration was similar in both groups. Airway management duration was shorter with the LMA Supreme®. Post-operative pharyngolaryngeal morbidity incidence and all symptoms' intensity were significantly increased after ETT as compared with LMA Supreme® anesthesia. At the end of the PACU stage, the incidence and mean NRS of post-operative hoarseness were reduced when LMA Supreme® was used as an alternative to the ETT (16% vs. 47%; P<0.01 and 9 vs. 19, P<0.01, respectively). Conclusion: We demonstrated that choosing an LMA Supreme® was an efficient pharyngolaryngeal morbidity-sparing strategy. Moreover, we showed that the LMA Supreme® and the ETT were equally effective airways for a routine gynecological laparoscopy procedure. [source] Breast-Conserving Therapy after Neoadjuvant Chemotherapy: Long-term ResultsTHE BREAST JOURNAL, Issue 2 2006Sushil Beriwal MD Abstract: The purpose of this study was to determine patterns of ipsilateral breast tumor recurrence (IBTR) and local-regional recurrence (LRR) after neoadjuvant chemotherapy and breast-conserving therapy (BCT). A total of 153 breast cancer patients were treated with neoadjuvant chemotherapy followed by conservative surgery and radiation therapy between 1980 and 2002. The clinical stage (American Joint Committee on Cancer [AJCC] 1997) at diagnosis was IIA in 22%, IIB in 28%, IIIA in 39%, and IIIB in 11%. The prechemotherapy T size distribution was less than 2 cm in 5 patients, 2.1,5 cm in 100 patients, and greater than 5.1 cm in 48 patients. Sixty-seven patients (44%) underwent cyclophosphamide, methotrexate, and 5-fluorouracil (CMF)-based chemotherapy and 86 (56%) underwent Adriamycin-based chemotherapy. Thirty-seven patients (24%) had a complete pathologic response in the breast. All procedures were performed by a single surgeon (G.F.S.). The surgery was local excision alone in 19 patients, local excision and axillary lymph node dissection (ALND) in 130 patients, and ALND alone in 4 patients. Eleven patients had positive surgical margins. Rates of LRR-, IBTR-, and distant metastasis (DM)-free survival were calculated by the Kaplan,Meier method. Patient and pathologic variables were then analyzed in an attempt to identify predictors of clinical outcome. With a median follow-up period of 55 months (range 6,200 months), eight patients developed LRR, five of which were classified as IBTR. Five- and 10-year actuarial rates of LRR-free, IBTR-free, and DM-free survival were 93% and 88%, 96% and 91%, and 70% and 58%, respectively. Pretreatment and pathologic parameters that positively correlated with IBTR were advanced stage (p = 0.03) and margin positivity (p = 0.04). No other clinical factors were predictive of higher recurrence. BCT results in a low rate of IBTR and LRR in appropriately selected patients. Advanced stage at presentation is associated with increased risk of IBTR, although overall recurrence is low. In selected cases, BCT is safe and an effective alternative to mastectomy., [source] Titanium versus Nontitanium Prostheses in Ossiculoplasty,THE LARYNGOSCOPE, Issue 9 2008Charles S. Coffey MD Abstract Objectives/Hypothesis: To compare the hearing outcomes and complications observed using either titanium or nontitanium prostheses in a 7-year consecutive series of ossiculoplasties performed by a single surgeon. Study Design: Retrospective. Methods: A database of ossicular reconstruction surgeries was reviewed for preoperative and postoperative audiometric data including air and bone conduction thresholds at four frequencies and speech reception thresholds. Outcomes were evaluated at time points less than and greater than 6 months postoperatively. Baseline demographic and surgical characteristics and postoperative complications were also noted. Results: A total of 105 cases had sufficient audiometric data available for analysis, including 80 performed with titanium and 25 with nontitanium implants. Follow-up ranged from 1.2 to 74.2 months, with a mean of 14.9 months. Mean air-bone gap at initial follow-up was 21.7 dB in the nontitanium group and 15.4 dB in the titanium group; this difference was significant (P = .01). Postoperative air-bone gap of less than 20 dB at initial follow-up was achieved in 50.0% of nontitanium cases and 77.1% of titanium cases (P = .012). This difference in "success" rates persisted at longer follow-up but did not achieve statistical significance. Mean speech reception thresholds at <6 months was 29.7 dB in the nontitanium group and 22.6 dB in the titanium group (P = .049). Extrusion was observed with two nontitanium prostheses (8.0%) and three titanium prostheses (3.8%) (P > .05). Conclusions: Titanium ossicular prostheses provide hearing outcomes superior to those of nontitanium prostheses when evaluated within 6 months after ossiculoplasty. [source] Retrograde Weight Implantation for Correction of Lagophthalmos,THE LARYNGOSCOPE, Issue 9 2004Chuan-Hsiang Kao MD Abstract Objectives: Gold weight implantation is the most commonly used method for surgical correction of paralytic lagophthalmos. Numerous techniques for placement of the weight have been described, yet complications with these methods continue to occur (implant migration or extrusion, wound infection, failure to correct the lagophthalmos, and excessive postoperative ptosis). We developed a retrograde, postlevator aponeurosis method for implantation to improve the placement and fixation of the weight. This study describes the rationale, technique, and surgical outcome of the retrograde approach. Study Design: Retrospective analysis. Methods: Data maintained and collected on 25 consecutive cases of retrograde upper lid weight implantation for paralytic lagophthalmos. Pre- and postoperative photographs were obtained, and patients were followed for at least 6 months. All procedures were performed by or under the direction of a single surgeon at tertiary academic medical centers (University of California, San Diego and University of Zurich, Switzerland). Results: Twenty-five consecutive patients were evaluated, 16 male and 9 female, ranging in age from 27 to 86 years. There were no surgical failures or perioperative complications and no instances of implant migration or extrusion. One patient developed a delayed infection requiring removal of the implant, and one patient required replacement of the gold weight with a platinum chain implant to better fit the contour of her eyelid. Conclusions: Retrograde implantation allows more accurate placement of the weight while creating a permanent circumferential seal for fixation. The procedure is minimally invasive, less traumatic than previous methods, and produces an excellent cosmetic result. The efficacy has been demonstrated in the outcome of the 25 cases described in this study. [source] The Becker Technique for Otoplasty: Modified and Revisited With Long-Term Outcomes,THE LARYNGOSCOPE, Issue 6 2000Dennis Lee MD Abstract Objectives To demonstrate a modification of the Becker technique for otoplasty and to evaluate the long-term results. Study Design Case series with follow-up survey assessment. Methods A sample of 16 patients treated by a single surgeon at an academic pediatric referral center who met the inclusion criteria was reviewed for surgical results and patient/parental satisfaction. Results A total of 30 ears underwent repair. Patients ranged from 4 to 17 years (mean age, 8.2 y) with an average follow-up of 4.6 years. One patient had an immediate postoperative hematoma from blunt trauma that was treated with good long-term results. No cases required revision surgery. Preservation of the antihelix with good to excellent ear symmetry was obtained in all patients at follow-up. All patients were happy or very happy with the surgical procedure. All patients had at least five of the six criteria for surgical success as defined by the survey. Conclusions This modification of the Becker technique of otoplasty is efficacious for correction of protruding ears with excellent long-term results. [source] Ulceration and antihypertensive use are risk factors for infection after skin lesion excisionANZ JOURNAL OF SURGERY, Issue 9 2010Anthony Penington Abstract Background:, A prospective audit was performed of wound complications of skin lesion excision in a private practice setting. Methods:, For 924 consecutive skin lesion excisions performed by a single surgeon, information was collected on tumour size and site, closure method and on risk factors of age, known diabetes, use of steroids, antihypertensives or anticoagulants and ulceration of the lesion. Patients were given written instructions to wet the wound in the shower after one or two days. A wound ,infection' event was recorded if the wound appeared inflamed or if the patient had been treated with antibiotics by any practitioner. Wound bleeding was recorded if the patient returned or attended elsewhere for management of bleeding. Results:, Sixty-seven wounds (7.25%) met the broad definition of ,infection' and 18 (1.9%) wounds suffered bleeding. Ulceration (odds ratio (OR) 3.15, P= 0.008) and use of antihypertensives (OR 2.5, P= 0.006) were independent risk factors for infection along with site and closure method. The patients who did not wet their wounds post-operatively were also at an increased risk of infection (OR 2.1, P= 0.018). Aspirin caused a slight, non-statistically significant increase in bleeding rate, and warfarin caused a larger, but still not statistically significant, increase in bleeding. Use of other anticoagulants caused a significant increase in bleeding (OR 10.9, P= 0.006). Conclusion:, Ulceration of the skin lesion and use of antihypertensives are significant risk factors for wound infection. Wetting surgical wounds with clean tap water does not increase, and may even reduce, wound infection rate. [source] 980-nm laser therapy versus varicose vein surgery in racially diverse Penang, MalaysiaANZ JOURNAL OF SURGERY, Issue 5 2009Murli N. Lakhwani Abstract Background:, Chronic venous disorders are conditions of increasing prevalence in the developing world, and venous ulceration is the terminal sequel. Currently there are only limited data on all aspects of this from Southeast Asia. The aim of the present study was to assess differences in the demography and outcome between varicose vein surgery (VVS) and the relatively new endovenous laser therapy (EVT) in patients from Penang, Malaysia. Methods:, A retrospective study was performed. Patients who presented to the outpatient clinic of the surgical department with saphenofemoral junction and/or saphenopopliteal junction incompetence associated with reflux of the great saphenous vein or small saphenous vein, respectively, underwent either surgery (1999,2004) or laser therapy (2004,2006). A single surgeon at a single institution performed all procedures. Results:, A total of 350 limbs were treated from 292 patients. Demographics, symptoms, outcomes and complications that arose in both groups were compared. There were significant improvements in pains, swelling, cramps and heaviness postoperatively (P < 0.001) in both groups. Deep venous thrombosis was present as a complication in the VVS group at 3.0%, but was absent altogether in the EVT group. Conclusions:, Although both are highly effective procedures, laser therapy has become popular as an elective procedure with its minimally invasive nature, cosmesis, rapid recovery and other advantages. Surgery remains an important and very cost-effective procedure, especially in a developing society such as Penang. [source] Oesophagectomy for tumours and dysplasia of the oesophagus and gastro-oesophageal junctionANZ JOURNAL OF SURGERY, Issue 4 2009Krishna Epari Abstract Background:, Neoadjuvant therapy, radical lymphadenectomy and treatment in high-volume centres have been proposed to improve outcomes for resectable oesophageal tumours. The aim of the present study was to review the oesophagectomy experience of a single surgeon with a moderate caseload who uses neoadjuvant therapy selectively and performs a conservative lymphadenectomy. Methods:, A retrospective review of prospectively collected data was performed. The study included 125 consecutive attempted oesophageal resections performed by a single surgeon (RC) from 1993 to 2006. Results:, All patients were staged with computed tomography and also laparoscopy for lower third and junctional tumours. Endoscopic ultrasound was used in 69%. Seventy-seven per cent were adenocarcinomas. Neoadjuvant therapy was used selectively in 23%. One hundred and twenty-one resections were carried out, giving an overall resection rate of 97% with an R0 resection in 82%. In-hospital mortality was 0.8%, clinical anastomotic leak 1.7% and median length of stay 14 days. Overall median and 5-year survival were 46 months and 47%. Stage-specific 5-year survival was 100%, 71%, 41% and 21% for stages 0, I, II and III, respectively. Isolated local recurrence occurred in 8%. Conclusions:, A moderate volume surgeon with specialist training in oesophageal resectional surgery can achieve a low mortality and anastomotic leak rate with good survival outcomes. The role for neoadjuvant therapy and radical lymphadenectomy is controversial and remains to be clearly defined. Accurate preoperative staging is essential for selection of patients for curative surgery with or without neoadjuvant therapy and for comparison of results. [source] LONG-TERM OUTCOMES AFTER LAPAROSCOPIC BILE DUCT EXPLORATION: A 5-YEAR FOLLOW UP OF 150 CONSECUTIVE PATIENTSANZ JOURNAL OF SURGERY, Issue 6 2008Andrew J. M. Campbell-Lloyd Background: The treatment of common bile duct stones discovered at routine intraoperative cholangiography includes postoperative endoscopic retrograde cholangiography or intraoperative laparoscopic common bile duct exploration. Given the equivalence of short-term outcome data for these two techniques, the choice of one over the other may be influenced by long-term follow-up data. We aimed to establish the long-term outcomes following laparoscopic common bile duct exploration and compare this with endoscopic retrograde cholangiography. Methods: One hundred and fifty consecutive patients underwent laparoscopic common bile duct exploration between March 1998 and March 2006 carried out by a single surgeon. All were prospectively studied for 1 month followed by a late-term phone questionnaire ascertaining the prevalence of adverse symptoms. Patients presented with a standardized series of questions, with reports of symptoms corroborated by review of medical records. Results: In 150 patients, operations included laparoscopic transcystic exploration (135), choledochotomy (10) and choledochoduodenostomy (2). At long-term follow up (mean 63 months), 116 (77.3%) patients were traceable, with 24 (20.7%) reporting an episode of pain and 18 (15.5%) had more than a single episode of pain. There was no long-term evidence of cholangitis, stricture or pancreatitis identified in any patient. Conclusion: Laparoscopic bile duct exploration appears not to increase the incidence of long-term adverse sequelae beyond the reported prevalence of postcholecystectomy symptoms. There was no incidence of bile duct stricture, cholangitis or pancreatitis. It is a safe procedure, which obviates the need and expense of preoperative or postoperative endoscopic retrograde cholangiography in most instances. [source] NS13P A PROSPECTIVE COMPARISON OF TWO CERVICAL INTERBODY FUSION CAGESANZ JOURNAL OF SURGERY, Issue 2007M. A. Hansen Purpose For some time the surgical management of chronic back pain has utilised interbody lumbar cages. Recently interbody cages for use in the cervical spine have been produced. Cervical cages provide initial stability during the fusion process. There is little literature comparing the performance of interbody cage systems due to their relative recent introduction. Methodology Patients with symptomatic cervical degeneration or traumatic lesions were treated with the dynamic ABC 2 Aesculap anterior cervical plating system and either the B-Braun Samarys or Zimmer cage systems. A single surgeon conducted all surgery. Pre- and post-operative radiological examinations were compared. Changes in disc height at affected and adjacent levels, lordosis and evidence of fusion were recorded. Patient outcome was measured with questionnaires. The modified Oswestry neck pain disability and Copenhagen neck disability scale scores were utilised to allow comparison between patients. Results A total of 43 patients were involved in the study (30 with the Zimmer cage system and 13 with the Samarys cage). Patient follow-up has been up to 12 months. Improvement in disability scores was shown in 90% of patients. Follow up imaging did not demonstrate subsidence of the cage or adjacent instability in either group. There was no statistical difference in complication rate between the two groups. Discussion Initial stability was provided by both interbody cervical spine cage system. Rates of fusion and symptomatic relief compared favourably to fusion involving autogenous bone graft without associated morbidity. Longer follow up is necessary to determine whether there is evidence of adjacent level instability or vertebral end-plate subsidence. [source] THYROIDECTOMY IS SAFE AND EFFECTIVE FOR RETROSTERNAL GOITREANZ JOURNAL OF SURGERY, Issue 4 2006Ajay Chauhan Background: Retrosternal goitre was defined as any thyroid enlargement identified below the thoracic inlet at operation, with the patient's neck held in extension. The aim of this study was to determine the characteristics of the patients, the goitres, the surgery and its morbidity (including tracheomalacia, recurrent laryngeal nerve palsy and hypocalcaemia) and the incidence of malignancy in order to establish guidelines for managing patients with a retrosternal goitre. Methods: Data were collected prospectively on all thyroidectomies carried out by a single surgeon over 14 years. Patients underwent appropriate preoperative assessment and thyroidectomy was carried out using a standardized capsular dissection technique. There were 199 cases of retrosternal extension. Results: Retrosternal extension was significantly more common on the left side than on the right side (ratio 3:2, P < 0.05). Most patients (83.4%) had significant symptoms that were relieved by surgery. Of the 199 thyroidectomies, none required a sternal split. The rate of malignancy was low (2.5%). Postoperative morbidity was 30%, the majority being asymptomatic temporary hypocalcaemia. There were no patients with permanent recurrent laryngeal nerve palsies or permanent hypoparathyroidism. There was one case of tracheomalacia. There was no death. Conclusion: Retrosternal goitre is a frequently symptomatic condition, with a low but definite rate of malignancy. Surgery is usually possible through a cervical incision and with an acceptable risk of significant morbidity. Thyroidectomy should be recommended as the treatment of choice. [source] PREDICTING IATROGENIC GALL BLADDER PERFORATION DURING LAPAROSCOPIC CHOLECYSTECTOMY: A MULTIVARIATE LOGISTIC REGRESSION ANALYSIS OF RISK FACTORSANZ JOURNAL OF SURGERY, Issue 3 2006Kamran Mohiuddin Background: Seventeen independent risk factors were examined using multivariate logistic regression analysis to develop a profile of patients most likely at risk from iatrogenic gall bladder perforation (IGBP) during laparoscopic cholecystectomy. Methods: Since 1989, a prospectively maintained database on 856 (women, 659; men, 197) consecutive laparoscopic cholecystectomies by a single surgeon (R. J. F.) was analysed. The mean age was 48 years (range, 17,94 years). The mean operating time was 88 min (range, 25,375 min) and the mean postoperative stay was 1 day (range, 1,24 days). There were 311 (women, 214; men, 97) IGBP. Seventeen independent variables, which included sex, race, history of biliary colic, dyspepsia, history of acute cholecystitis, acute pancreatitis and jaundice, previous abdominal surgery, previous upper abdominal surgery, medical illness, use of intraoperative laser or electrodiathermy, performance of intraoperative cholangiogram, positive intraoperative cholangiogram, intraoperative common bile duct exploration, presence of a grossly inflamed gall bladder as seen by the surgeon intraoperatively and success of the operation, were analysed using multivariate logistic regression for predicting IGBP. Results: Multivariate logistic regression analysis against all 17 predictors was significant (,2 = 94.5, d.f. = 17, P = 0.0001), and the variables male sex, history of acute cholecystitis, use of laser and presence of a grossly inflamed gall bladder as seen by the surgeon intraoperatively were individually significant (P < 0.05) by the Wald ,2 -test. Conclusion: Laparoscopic cholecystectomy, using laser, in a male patient with a history of acute cholecystitis or during an acute attack of cholecystitis is associated with a significantly higher incidence of IGBP. [source] Regional anaesthesia and propofol sedation for carotid endarterectomyANZ JOURNAL OF SURGERY, Issue 7 2005Christopher Barringer Background: Many surgeons now perform carotid endarterectomy under regional anaesthesia. The aim of the present study was to review a sedation technique using a computer-controlled infusion of propofol. Methods: A consecutive series of 84 carotid endarterectomies done by a single surgeon and commenced under regional anaesthesia with sedation was studied. There were 54 men and 27 women (three bilateral procedures), with a median age of 71 years (range 48,87 years). All patients had carotid stenosis >70% 80 procedures were done for symptomatic disease and three asymptomatic patients were treated before cardiac surgery (one bilateral). Results: Seventy-seven procedures were completed under regional anaesthesia and sedation alone; seven required conversion to general anaesthetic, usually for intolerance of the operation. An intraoperative shunt was required on only four occasions (5%). Postoperatively eight patients required critical care monitoring, usually for blood pressure control. The remainder were nursed on the vascular ward, and 68% were discharged home on the day after surgery. No patient died, but there were two neurological complications. One patient had a cerebellar stroke 10 days after surgery, but recovered fully after 4 months. A second developed cerebral oedema due to severe intraoperative hypertension and required intensive care for 15 days. He too recovered fully. Five patients had a further episode of transient cerebral ischaemia within 1 month of operation, but in all cases duplex imaging showed a widely patent carotid and there were no sequelae. Conclusion: Target controlled propofol infusion is an effective method of sedation in patients undergoing carotid endarterectomy. [source] Initial experience of abdominal aortic aneurysm repairs in BorneoANZ JOURNAL OF SURGERY, Issue 10 2003Ming Kon Yii Background: Abdominal aortic aneurysms (AAA) repairs are routineoperations with low mortality in the developed world. There arefew studies on the operative management of AAA in the Asian population. This study reports the initial results from a unit with no previousexperience in this surgery by a single surgeon on completion oftraining. Methods: All patients with AAA repair from a prospective databasebetween 1996 and 1999 in the south-east Asian state of Sarawak inBorneo Island were analyzed. Three groups were identified on presentationaccording to clinical urgency of surgery. Elective surgery was offeredto all good risk patients with AAA of , 5 cm. All symptomatic patients were offered surgery unless contraindicatedmedically. Results: AAA repairs were performed in 69 patients: 32 (46%)had elective repairs of asymptomatic AAA; 20 (29%) hadurgent surgery for symptomatic non-ruptured AAA; and 17 (25%)had surgery for ruptured AAA. The mortality rate for elective surgery was6%; the two deaths occurred early in the series with thesubsequent 25 repairs recorded no further mortality. The mortalityrates for the urgent, symptomatic non-ruptured AAA repair and rupturedAAA repair were 20% and 35%, respectively. Cardiacand respiratory complications were the main morbidities. Sixty-three patients seen during this period had no surgery; threepresented and died of ruptured AAA, 34 had AAA of , 5 cmin diameter, and 26 with AAA of , 5 cmdiameter had either no consent for surgery or serious medical contraindications. Conclusion: This study showed that AAA can be repaired safely byhighly motivated and adequately trained surgeons in a hospital withlittle previous experience.

MOON Objectives:, We report the largest series of laparoscopic dismembered pyeloplasty for treatment of primary and secondary uretero-pelvic junction (UPJ) obstruction, reviewing the current status of this procedure. Methods:, A total of 170 consecutive cases of laparoscopic pyeloplasty (156 for primary and 14 for secondary UPJ obstruction) were performed or supervised by a single surgeon (C.G.E). A four port extraperitoneal approach was used in all but three cases, which were performed transperitoneally. Results:, Median operative time was 140 min. The complication rate was 7.1% and conversion rate was 0.6% with no conversion in the last 161 cases. The median postoperative hospitalisation was 3 nights. Crossing vessels were encountered in 42% of cases and in 11 patients coexisting renal calculi were successfully removed. At a median follow-up of 12 months, the success rate was 96.2%. Conclusions:, Laparoscopic dismembered pyeloplasty produces functional results comparable to that of open surgery with the advantages of a minimally invasive procedure. Our results are consistent with previous series and support the view that laparoscopic pyeloplasty is moving rapidly towards replacing open surgery as the gold standard in treatment of UPJ obstruction. [source] Chordoma and chondrosarcoma: Similar, but quite different, skull base tumorsCANCER, Issue 11 2007Kaith Almefty BBA Abstract BACKGROUND Chordoma and chondrosarcoma of the skull base are frequently amalgamated because of similar anatomic location, clinical presentation, and radiologic findings. The chondroid chordoma variant has been reported to carry a better prognosis. The objective of the current study was to investigate the distinctions between these 3 entities. METHODS The data concerning 109 patients with chordoma, chondroid chordoma, and chondrosarcoma who were treated by a single surgeon with maximum surgical resection and frequently by adjunct proton beam radiotherapy between 1990 and 2006 were analyzed retrospectively. Pathologic distinction was established by cytokeratin and epithelial membrane antigen staining. Clinical, radiologic, pathologic, and cytogenetic studies were analyzed in relation to disease recurrence and death. RESULTS The average follow-up was 48 ± 37.5 months (range, 1,191 months). There were no reliable distinguishing clinical or radiologic features noted between the groups. Chondrosarcoma patients had a significantly better outcome compared with chordoma patients with regard to survival and recurrence-free survival (P = .028 and P < .001, respectively), whereas patients with chondroid chordoma had a poor outcome similar to chordoma patients with regard to survival and recurrence-free survival (P = .337 and P = .906, respectively). CONCLUSIONS Chordoma and chondrosarcoma differ with regard to their origin and histology, and differ markedly with regard to outcome. Chondroid chordomas behave in a manner that is clinically similar to chordomas, with the same prognosis. Both chordoma types demonstrate an aggressive clinical course and poor outcome after disease recurrence. The optimal treatment for all groups of patients involves radical surgical resection followed by high-dose radiotherapy in patients with chordomas. Radiotherapy may not be necessary in patients with low-grade chondrosarcoma. Cancer 2007. © 2007 American Cancer Society. [source] Audit of stapedectomy results in a district general hospitalCLINICAL OTOLARYNGOLOGY, Issue 4 2002A. Banerjee We report a series of 100 stapes operations performed for otosclerosis. The problems in reporting the results of stapedectomies are discussed. The audit showed a difference in the measured results between two consultants. As a result, the consultant with the worse outcome chose to stop operating on patients with otosclerosis. The advantages and disadvantages of a single surgeon performing all the cases are discussed. We advocate a central registry of all surgeons performing stapes surgery to allow periodic national comparative audits. [source] | |||||||||||||||||||||||||
