Mariano Palermo, Edgardo Serra
Background: Gastric bypass is a restrictive and malabsorptive surgery. The restrictive part consists in the creation of a small gastric pouch. The gastrointestinal bypass serves as the malabsorptive element. Aim: To describe a simplified gastric bypass approach for morbid obese patients, showing our results, and also remarking the importance of this technique for reducing the learning curve. Method: The patient is positioned in a split legs position and carefully strapped to the operating room table, with the surgeon between the patient's legs...

Background: Among the options for surgical treatment of obesity, the most widely used has been the Roux-en-Y gastric bypass. The gastrojejunal anastomosis can be accomplished in two ways: handsewn or using circular and linear stapled. The complications can be divided in early and late. Aim: To compare the incidence of early complications related with the handsewn gastrojejunal anastomosis in gastric bypass using Fouchet catheter with different diameters. Method: The records of 732 consecutive patients who had undergone the bypass were retrospectively analyzed and divided in two groups, group 1 with 12 mm anastomosis (n=374), and group 2 with 15 mm (n=358)...

OBJECTIVE: to describe the clinical and epidemiological profile of acute appendicitis (AA) of the patients treated at a referral center in the Juiz de Fora macro-region, Minas Gerais State, Brazil. METHODS: we conducted a retrospective, observational study in the Dr. Mozart Geraldo TeixeiraEmergency Hospital. We selected 638 patients diagnosed with AA, and analyzed the variables gender, age, evolutionary phase, length of hospital stay, pathological diagnosis, use of antibiotics, use of drains, complications and mortality...

OBJECTIVE: : to evaluate the epidemiology and outcomes of surgical treatment of patients with Mirizzi Syndrome (MS) grades III and IV, the most advanced according to Csendes classification. METHODS: : we conducted a retrospective, cross-sectional study by reviewing records of thirteen patients with grades III and IV MS operated from December 2001 to September 2013, among the 3,691 cholecystectomies performed in the period. RESULTS: : the incidence of MS was 0...

OBJECTIVE: to describe our experience with a minimally invasive approach for persistent vesicourethral anastomotic leak (PVAL) after Laparoscopic Radical Prostatectomy (LRP). METHODS: from 2004 to 2011, two surgeons performed LRP in 620 patients. Ten patients had PVAL, with initially indicated conservative treatment, to no avail. These patients underwent a minimally invasive operation, consisting of an endoscopically insertion of two ureteral catheters to direct urine flow, fixed to a new urethral catheter...

BACKGROUND: Once a biliary injury has occurred, repair is done by a hepaticojejunostomy. The most common procedure is to perform a dilatation with balloon with a success of 70 %. Success rates range using biodegradable stents is from 85% to 95%. Biodegradable biliary stents should change the treatment of this complication. AIM: To investigate the use of biodegradable stents in a group of patients with hepaticojejunonostomy strictures. METHODS: In a prospective study 16 biodegradable stents were placed in 13 patients with hepaticojejunostomy strictures secondary to bile duct repair of a biliary surgical injury...

OBJECTIVE: to evaluate the feasibility, safety and benefits of minimally invasive surgery for resection of gastric submucosal tumor (GSMT). METHODS: we conducted a retrospective study of medical records of patients undergoing endoscopy-assisted laparoscopic resection of gastric submucosal tumors (prospectively collected) from 2011 to 2014. We evaluated clinical data, surgical approach, clinicopathological characteristics of the GSMT (size, location, histopathological and immunohistochemical exams), outcome and patients follow-up...

BACKGROUND: Several researchers seek methods for the selection of homogeneous groups of animals in experimental studies, a fact justified because homogeneity is an indispensable prerequisite for casualization of treatments. The lack of robust methods that comply with statistical and biological principles is the reason why researchers use empirical or subjective methods, influencing their results. OBJECTIVE: To develop a multivariate statistical model for the selection of a homogeneous group of animals for experimental research and to elaborate a computational package to use it...

OBJECTIVE: To determinate the efficacy in the treatment of ureteral estenoses after renal transplantation with metallic self-expandable stent. MATERIALS AND METHODS: From october of 1995 to april of 2002, 8 ureteral obstruction post renal transplantation have treated by means of implants of a metallic self-expandable stent (6 men and 2 women). The average time of pursuit was of 30 months (rank 2-53 months). In this work the severity and location of the estenosis are analysed, the method of implant of the stent, the permeability of the same one, the levels of creatinine pre and postimplant and the complications derived from the same one...
