Intestinal intussusception of Meckel's diverticulum, a case report and literature review of the last five years.

Meckel's diverticulum is the most common gastrointestinal tract anomaly. It arises from the incomplete closure of the omphalomesenteric conduit, which is a true diverticulum at the antimesenteric border of the ileum. Although the majority of patients are asymptomatic, they can present with inflammation, hemorrhage, intussusception, intestinal obstruction, and perforation, among others; this constitutes an important differential diagnosis for acute abdomen.

Sleeve gastrectomy with anti-reflux procedures.

Objective: Sleeve gastrectomy is the fastest growing surgical procedure to treat obesity in the world but it may cause or worsen gastroesophageal reflux disease. This article originally aimed to describe the addition of anti-reflux procedures (removal of periesophageal fats pads, hiatoplasty, a small plication and fixation of the gastric remnant in position) to the usual sleeve gastrectomy and to report early and late results.

Methods: Eighty-eight obese patients that also presented symptoms of gastroesophageal reflux disease were submitted to sleeve gastrectomy with anti-reflux procedures.

Sleeve gastrectomy with transit bipartition: a potent intervention for metabolic syndrome and obesity.

Objective: To present 5-year results of sleeve gastrectomy (SG) with transit bipartition (TB) as a metabolic intervention for obesity.

Background: Recent data suggest that high glycemic index foods may lead to a hormonally hyperactive proximal gut and a hypoactivate distal gut, which are linked to metabolic syndrome. TB was designed to counterbalance these effects.

Metabolic effects of an entero-omentectomy in mildly obese type 2 diabetes mellitus patients after three years.

Background: Various digestive tract procedures effectively improve metabolic syndrome, especially the control of type 2 diabetes mellitus. Very good metabolic results have been shown with vertical gastrectomy and entero-omentectomy; however, the metabolic effects of an isolated entero-omentectomy have not been previously studied.

Methods: Nine patients with type 2 diabetes mellitus and a body mass index ranging from 29 to 34.

[Predictive factors for cholelithiasis in the morbidly obese submitted to Roux-en-Y gastroplasty].

Objective: This study intended to evaluate predictive factors for cholelithiasis in morbidly obese submitted to gastroplasty with "Y" de Roux reconstruction.

Methods: The population under study was a group of obese patients enrolled in a program of surgical procedure for morbid obesity at the Department of Surgery, College of Medical Sciences, Santa Casa de São Paulo. The exclusion criteria were: patients previously cholecystectomized, patients with diagnosis of pre-operative cholelithiasis and patients with a questionable ultrasonography about existence of billiary stones.
