SURGICAL INDICATIONS AND PROCEDURES FOR BLEEDING PEPTIC ULCER

DIGESTIVE ENDOSCOPY, Issue 2010
Nobutsugu Abe
Recent important insights into the surgical treatment of bleeding peptic ulcer are reviewed in this article. Although the widespread use of endoscopic treatment and interventional radiology has reduced the number of surgical cases, surgery still plays a pivotal role in managing bleeding peptic ulcer. Failure to stop the bleeding by endoscopy and/or interventional radiology is the most important indication for emergency surgery. An early elective/planned surgery after the initial endoscopic control to prevent life-threatening rebleeding seems justified in patients who have risk factors for rebleeding, although its true efficacy still remains controversial. The surgical procedures in emergency situations should be limited to safe hemostasis. The addition of acid-reduction surgery may be unnecessary as a result of the increasing utilization of proton pump inhibitors. Angiographic embolization may be a less invasive alternative to surgery, and may further enhance endoscopic hemostasis. [source]

Presentation and therapy of myelolipoma

INTERNATIONAL JOURNAL OF UROLOGY, Issue 3 2005
ANDREAS MEYER
Abstract, Background:, Adrenal myelolipoma is a rare and benign, hormonally inactive tumor frequently discovered incidentally. Because of the increasing rate of detection of adrenal myelolipoma, use of the correct diagnostic examination and treatment, with respect to surgical excision or regular controls, is continually gaining importance. We report herein on the largest series of surgically treated patients with adrenal myelolipoma from a single institute. Methods:, The clinical charts of 12 patients who underwent adrenal surgery for myelolipoma were reviewed. Follow up was carried out by means of re-examination or by personal contact with the primary physician. It was possible to perform a re-examination on eight of the 12 patients 6.9 years after the operation: one patient had died 5.2 years after surgery. Results:, Diagnosis of adrenal myelolipoma was made incidentally in seven patients, and during examination for reasons of unspecific abdominal or flank pain in five patients. A transabdominal approach was taken in five patients, a subcostal approach was taken in three patients and a translumbal approach was taken in four patients. At the follow up, all formerly symptomatic patients were free of symptoms. No recurrence could be seen; however, in one patient a contralateral adrenal myelolipoma had developed. Conclusions:, Symptomatic tumors, growing tumors or tumors larger than 10 cm should be excised surgically by means of an endoscopic or conventional approach, depending on the size. Surgical indication should not be liberalized by the introduction of more gentle operative techniques such as the translumbal or the endoscopic approach. A close follow up should be maintained in the case of patients free of symptoms, and for those with a definite diagnosis from imaging procedures. [source]

Diagnostic Coronary Angiography in Patients with Peripheral Arterial Disease: A Sub-study of the Coronary Artery Revascularization Prophylaxis Trial

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2008
SANTIAGO GARCIA M.D.
Background: Although patients in need of elective vascular surgery are often considered candidates for diagnostic coronary angiography, the safety of this invasive study has not been systematically studied in a large cohort of patients scheduled for an elective vascular operation. The goal of this sub-study of the Coronary Artery Revascularization Prophylaxis (CARP) trial was to assess the safety of coronary angiography in patients with peripheral vascular disease. Methods: The CARP trial tested the long-term benefit of coronary artery revascularization prior to elective vascular operations. Among those patients who underwent diagnostic coronary angiography during screening for the trial, the associated complications were determined at 24 hours following the diagnostic procedure. Results: Over 5,000 patients were screened during a 4-year recruitment period at 18 major VA medical centers and the present cohort consists of 1,298 patients who underwent preoperative coronary angiography. Surgical indications for vascular surgery included an expanding aortic aneurysm (AAA) (n = 446; 34.4%) or arterial occlusive disease with either claudication (n = 457; 35.2%) or rest pain (n = 395; 30.4%). A total of 39 patients had a confirmed complication with a major complication identified in 17 patients (1.3%). Complication rates were higher in patients with arterial occlusive symptoms compared with expanding aneurysms (1.8% vs. 0.5%; P = 0.07) and were not dissimilar with femoral (2.8%) versus nonfemoral (4.7%) access sites (P = 0.42). Conclusions: Coronary angiography is safe in patients with peripheral arterial disease undergoing preoperative coronary angiography. The complication rate is higher in patients with symptoms of arterial occlusive disease. [source]

Tonsil size as a predictor of cardiac complications in children with sleep-disordered breathing,

THE LARYNGOSCOPE, Issue 6 2010
Eduardo Homrich Granzotto MD
Abstract Objectives/Hypothesis: The primary objective was to evaluate the association of palatine (T/P) tonsil size determined by radiography with pulmonary artery pressure (PAP) measured by Doppler echocardiography in children with surgical indication for adenotonsillar hypertrophy. The secondary objective was to evaluate if tonsil size could help to identify children at higher risk of pulmonary artery hypertension (PAH). Study Design: Cross-sectional study. Methods: The study was conducted with a consecutive sample of children with indication of adenotonsillectomy for sleep-disordered breathing. T/P was measured by lateral neck radiography, PAP by echodopplercardiography, and symptoms and quality of life by the Obstructive Sleep Apnea (OSA)-18 questionnaire. T/P was plotted in a receiver operating characteristic (ROC) curve to determine the best cut-off point to identify children with PAH. Results: A total of 45 children participated in the study. The mean age was 72.0 ± 32.3 months, and six (13%) patients had PAH. Correlation between systolic PAP and T/P was strong (r = 0.624; P < .0001). T/P was significantly higher in patients with PAH (P < .001). OSA-18 score did not significantly correlate with the variables. The cut-off point identified in the ROC was 0.66, which was the minimum T/P where sensitivity was still 100%. Mean systolic pulmonary artery pressure in children with T/P >0.66 was significantly higher than in those with T/P <0.66 (P < .001). Conclusions: T/P showed a good correlation with PAP in children with adenotonsillar hypertrophy and surgical indication for sleep-disordered breathing. Children with T/P >0.66 can be at greater risk for cardiac complications and should be submitted to complementary studies with echodopplercardiography or given preference for surgery. [source]

Palliative goals, patient selection, and perioperative platelet management: Outcomes and lessons from 3 decades of splenectomy for myelofibrosiswith myeloid metaplasia at the Mayo Clinic

CANCER, Issue 2 2006
Ruben A. Mesa MD
Abstract BACKGROUND. Although splenectomy may palliate massive splenomegaly in patients with myelofibrosis with myeloid metaplasia, this procedure carries significant risks. The authors retrospectively analyzed their experience with splenectomy over the course of 30 years to analyze the impact of improved techniques, antimicrobials, and aggressive postoperative control of platelet counts on outcome. METHODS. A total of 314 patients underwent splenectomy between 1976 and 2004 for mechanical symptoms (= 156 patients [49%]), anemia (= 78 patients [25%]), portal hypertension (= 47 patients [15%]), or thrombocytopenia (= 33 patients [11%]). Of a total of 91 patients studied during the last decade, 69 patients (76%) experienced a palliative benefit for their primary surgical indication for a median of 12 months (range, 1-91 months). RESULTS. Perioperative complications occurred in 87 patients (27.7%) including infection (= 31 patients [9.9%]), thrombosis (= 31 patients [9.9%]), or bleeding (= 44 patients [14%]), 21 of which (6.7% of all patients) were fatal. Perioperative thrombohemorrhagic complications decreased in the last decade through the use of platelet apheresis and the prompt use of cytoreductive agents to counteract postsplenectomy thrombocytosis. Survival after splenectomy was found to be decreased in patients with preoperative thrombocytopenia (<100 × 109/L [P = 0.006]) but not by indication, myelofibrosis with myeloid metaplasia (MMM) prognostic score, or the decade in which splenectomy was performed. CONCLUSIONS. The lack of improvement in overall postsplenectomy survival over time may be a reflection on the failure of medical therapy to improve survival in patients with MMM.

Macular edema in epiretinal membrane and vitreomacular traction

ACTA OPHTHALMOLOGICA, Issue 2009
C CREUZOT
Purpose Macular edema occuring during macular diseases is a frequent situation. The purpose of this course is to highlight the clinical signs and the different treatments which can be used to treat macular edema occuring during epiretinal membrane and vitreomacular traction syndrome. Methods Macular edema is frequently associated with epiretinal membranes and vitreomacular traction. Up to now, no specific preoperative macular edema phenotype can predict the postoperative recovery. Different methods were proposed to improve functional results: ILM peeling, intravitreal steroid injection, intravitreal antiangiogenic injections, Results The widespread use of transconjunctival vitrectomy, the combination of cataract and macular surgeries will probably change the indication of macular surgery leading to sooner surgical indications for better recovery. By contrast, vitreomacular traction often leads to a rapidly progressive visual loss. The analysis should distinguish diffuse diabetic macular edema which remains the only validated surgical indication of macular edema in diabetes and the vitreomacular traction without diabetes. This latter needs a rapid surgical management as macular edema is often severe. Conclusion Macular edema is a frequent situation associated to macular disease. It can compromise the outcomes after macular surgeriy. Attempts to define the best moment to consider surgery should improve the functional results. [source]

EXPERIENCES OF SELF-EXPANDABLE METALLIC STENT FOR COLORECTAL OBSTRUCTIONS: 70 CASES

DIGESTIVE ENDOSCOPY, Issue 2004
Yoshihisa Saida
ABSTRACT Clinical utilization of self-expandable metallic stent (EMS) endoprosthesis has come later for colorectal diseases than for other lesions. Recently, EMS has been used for palliative insertions for strictures caused by malignant diseases or as a ,bridge to surgery' for obstructive colorectal cancers, with good clinical results increasingly reported in many western countries. Its application for benign strictures has been reported, but we believe that the surgical indications require more careful analysis because of the absence of data concerning long-term prognosis. The advantage of this technique in the treatment of colorectal strictures is that it limits invasiveness, such as in palliative or temporary stoma creation, thereby improving patient quality-of-life. Therefore, we believe that EMS endoprosthesis will play a key role in this field. We are awaiting the introduction of the metallic stent for the colon and the associated kit, as well as the Japanese government's approval for reimbursement for this procedure. [source]

Pediatric submandibular triangle masses: a fifteen-year experience,

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2004
Neil G. Hockstein MD
Abstract Background. The purpose of this study was to evaluate the surgical results of pediatric submandibular triangle masses, with specific attention to neoplastic processes. Methods. We retrospectively reviewed the medical records of 105 patients aged 6 months to 21 years who underwent surgery in the submandibular triangle at a major pediatric tertiary care hospital from 1987 to 2001. Results. One hundred five patients who underwent surgery in the submandibular triangle were included in the study. Twenty patients had neoplastic processes, six of which were of primary salivary origin (two mucoepidermoid carcinomas and four pleomorphic adenomas). Twenty-four patients underwent excision of inflamed or infected lymph nodes, and 23 patients underwent excision of inflamed or infected submandibular glands. Thirty-eight patients were included who underwent surgery for sialorrhea or to gain access for another surgical procedure. Complications included tumor recurrence, transient and permanent marginal mandibular nerve weakness, ranula, postoperative fluid collection, and cellulitis. Duration of follow-up ranged from no follow-up to 11 years. Conclusion. Surgical excision of submandibular triangle masses is uncommon. We present our experience with these lesions, with a discussion of diagnosis, surgical indications, and surgical complications. © 2004 Wiley Periodicals, Inc. Head Neck26: 675,680, 2004 [source]

Japanese guidelines for prevention of perioperative infections in urological field

INTERNATIONAL JOURNAL OF UROLOGY, Issue 10 2007
Tetsuro Matsumoto
Abstract: For urologists, it is very important to master surgical indications and surgical techniques. On the other hand, the knowledge of the prevention of perioperative infections and the improvement of surgical techniques should always be considered. Although the prevention of perioperative infections in each surgical field is a very important issue, the evidence and the number of guidelines are limited. Among them, the preparation of guidelines has progressed, especially in gastrointestinal surgery. The Center for Disease Control and Prevention (CDC) proposed guidelines for the prevention of surgical site infections, which have been used worldwide. In urology, the original guidelines were different from those of general surgery, due to many endourological procedures and urine exposure in the surgical field. The Japanese Society of UTI Cooperative Study Group has thus framed these guidelines supported by The Japanese Urological Association. The guidelines consist of the following nine techniques: open surgeries, laparoscopic surgeries, transurethral resection of bladder tumor, ureterorenoscope and transurethral lithotripsy, transurethral resection of the prostate, prostate biopsy, cystourethroscope, pediatric surgeries in the urological field, and extracorporeal shock wave lithotripsy and febrile neutropenia. These are the first guidelines for the prevention of perioperative infections in the urological field in Japan. Although most of these guidelines were made using reliable evidence, there are parts without enough evidence. Therefore, if new reliable data is reported, it will be necessary for these guidelines to be revised in the future. [source]

Preclinical Cushing's syndrome: Report of seven cases and a review of the literature

INTERNATIONAL JOURNAL OF UROLOGY, Issue 4 2000
Masaaki Morioka
Abstract Background: Adrenal adenomas showing autonomous cortisol secretion without specific endocrine symptoms are sometimes discovered in patients with adrenal incidentalomas. This entity has been described as subclinical or preclinical Cushing's syndrome (PCS), but the endocrine data of reported cases have varied and the diagnostic criteria of PCS have been uncertain. Methods: We report seven Japanese cases of PCS due to a unilateral, solitary adrenal adenoma with examination of the endocrine data of these patients. The diagnostic parameters of subtle hypercortisolism and the risk of postoperative adrenal insufficiency and surgical indications are discussed and reviewed. Results: In the present cases, the most frequently found biochemical parameters of autonomous cortisol secretion were a low adrenocorticotropic hormone (ACTH) level (100%) and insufficient suppression of cortisol by low-dose dexamethasone (85.7%). Unilateral accumulation of radiopharmaceuticals in tumors was also frequently observed (100%). A postoperative hydrocortisone supplement was given to six of the seven patients for 5,122 days. It was not given to case 4, because a moderate response of 11-deoxycortisol to metyrapone was identified. Plasma ACTH levels and the diurnal rhythm of plasma cortisol rapidly recovered within 3 weeks postoperatively in six of the seven cases. Conclusion: This entity is heterogeneous and various degrees of cortisol excess have been observed. It should be diagnosed in the wide spectrum and the risk of adrenal insufficiency after surgery should be evaluated by dynamic tests such as the corticotropin-releasing hormone (CRH) test. Based on the results of the present study and a review of the literature, PCS patients may not require hydrocortisone supplement therapy for a long period. [source]

The Blalock-Taussig Shunt

JOURNAL OF CARDIAC SURGERY, Issue 2 2009
Shi-Min Yuan M.D.
This warrants us a zest in making a comprehensive survey on this subject. Methods: Articles were extensively retrieved from the MEDLINE database of National Library of Medicine USA if the abstract contained information relevant to the B-T shunt in terms of the conduit options, modified surgical techniques, surgical indications, short- and long-term results, complications, and prognosis. Further retrieval was undertaken by manually searching the reference list of relevant papers. Results: Classical or modified B-T shunts, either on ipsilateral or contralateral side to the aortic arch, can be performed on patients of any age with minimum postoperative complications and low operative mortality. Expended polytetrafluoroethylene has gained satisfactory long-term patency rate in the construction of the modified B-T shunt. Excellent pulmonary artery growth was observed in the patients with a modified B-T shunt, and it has shown superb prognosis over the classic with regard to hemodynamics, patency rate, and survival. Conclusions: The modified B-T shunt that was developed on basis of the classic fashion remains the preferable palliative procedure aiming at enhancing pulmonary blood flow for neonates and infants with complicated cyanotic congenital heart defects. The modified B-T shunt is technically simpler with less dissection, and blood flow to the respective arm is not jeopardized. It has been proved to be of low risk, excellent palliation, and is associated with excellent pulmonary artery growth, has become the most effective palliative shunt procedure of today. [source]

Is splenectomy a dyslipidemic intervention?

MICROSURGERY, Issue 2 2009
Experimental response of serum lipids to different diets, operations
Spleen removal may be recommended during organ transplantation in ABO-incompatible recipients as well as for hypoperfusion of the grafted liver, besides conventional surgical indications, but elevation of serum lipids has been observed in certain contexts. Aiming to analyze the influence of two dietary regimens on lipid profile, an experimental study was conducted. Methods: Male Wistar rats (n = 86, 333.0 ± 32.2 g) were divided in four groups: group 1: controls; group 2: sham operation; group 3: total splenectomy; group 4: subtotal splenectomy with upper pole preservation; subgroups A (cholesterol reducing chow) and B (cholesterol-rich mixture) were established, and diet was given during 90 days. Total cholesterol (Tchol), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and triglycerides were documented. Results: After total splenectomy, hyperlipidemia ensued with cholesterol-reducing chow. Tchol, LDL, VLDL, triglycerides, and HDL changed from 56.4 ± 9.2, 24.6 ± 4.7, 9.7 ± 2.2, 48.6 ± 11.1, and 22.4 ± 4.3 mg/dL to 66.9 ± 11.4, 29.9 ± 5.9, 10.9 ± 2.3, 54.3 ± 11.4, and 26.1 ± 5.1 mg/dL, respectively. Upper pole preservation inhibited abnormalities of Tchol, HDL, VLDL, and triglycerides, and LDL decreased (23.6 ± 4.9 vs. 22.1 ± 5.1, P = 0.002). Higher concentrations were triggered by splenectomy and cholesterol-enriched diet (Tchol 59.4 ± 10.1 vs. 83.9 ± 14.3 mg/dL, P = 0.000), and upper-pole preservation diminished without abolishing hyperlipidemia (Tchol 55.9 ± 10.0 vs. 62.3 ± 7.8, P = 0.002). Conclusions: After splenectomy, hyperlipidemia occurred with both diets. Preservation of the upper pole tended to correct dyslipidemia in modality A and to attenuate it in subgroup B. © 2008 Wiley-Liss, Inc. Microsurgery, 2009. [source]

RISK FACTORS FOR POSTOPERATIVE PULMONARY COMPLICATIONS IN UPPER ABDOMINAL SURGERY

ANZ JOURNAL OF SURGERY, Issue 3 2007
Fikret Kanat
Background: Pulmonary complications are the most frequent cause of postoperative morbidity and mortality in upper abdominal surgery (UAS). We aimed to examine the influence of possible preoperative, operative and postoperative risk factors on the development of early postoperative pulmonary complications (POPC) after UAS. Methods: A prospective study of 60 consecutive patients was conducted who underwent elective UAS in general surgical unit. Each patient's preoperative respiratory status was assessed by an experienced chest physician using clinical examination, chest radiographs, spirometry and blood gas analysis . Anaesthetical risks, surgical indications, operation time, incision type, duration of nasogastric catheter and mobilization time were noted. Forty-eight hours after the operation, pulmonary examinations of the patients were repeated. Results: Postoperative pulmonary complications were observed in 35 patients (58.3%). The most common complication was pneumonia, followed by pneumonitis, atelectasis, bronchitis, pulmonary emboli and acute respiratory failure. The presence of preoperative respiratory symptoms and the spirometric parameter of forced expiratory volume in 1 s/forced vital capacity were the most valuable risk factors for early prediction of POPC. The sensitivity, specificity and diagnostic efficiency of the presence of preoperative respiratory symptoms in the POPC prediction were 70, 61 and 66%, respectively. Conclusion: We recommend a detailed pulmonary examination and spirometry in patients who will undergo UAS by chest physicians to identify the patients at high risk for POPC, to manage respiratory problems of the patients before surgery and also to help surgeons to take early measures in such patients before a most likely POPC occurrence. Improvement of lung function in those patients at risk for POPC before operation may decrease morbidity in surgical patients. [source]

Long-term outcome of per anum intersphincteric rectal dissection with direct coloanal anastomosis for lower rectal cancer

COLORECTAL DISEASE, Issue 5 2005
J.-H. Yoo
Abstract Objective, The authors have performed per anum intersphincteric rectal dissection. With direct coloanal anastomosis for cases of lower rectal cancer in which the distal surgical margin is difficult to secure by the double stapling technique. The aim of this study was to evaluate the long-term outcome and to clarify the surgical indications for this operation. Patients and methods, Between 1993 and 2002, 31 patients underwent per anum intersphincteric rectal dissection with direct coloanal anastomosis. Of these, two patients (one stage 0 and one stage IV) were excluded from the analysis of oncological outcome. The remaining 29 patients formed the basis of this study. The median follow-up was 57 months (range 6,106 months). Results, Local recurrence and distant metastasis developed in 9 and 3 patients, respectively. Local recurrence rate for pT1 was significantly lower than that for pT2/T3 disease. The local recurrence rate cases with tumours less than 3 cm was significantly lower than that for tumours sized 3 cm or more. The distant metastasis rate for cases with lymph node metastasis was significantly higher than that for cases without lymph node metastasis. There was an association between distant metastasis and TNM or pT stage. The overall survival rates for stage I, II and III were 85%, 80% and 89%, respectively. No significant defference was seen in total Cleveland Clinic incontinence score between per anum intersphincteric rectal dissection with direct coloanal anastomosis and the double stapling technique. Conclusion, The surgical indications of this operation should be limited to patients with T1 rectal cancer or tumours less than 3 cm. [source]
