BACKGROUND Intragastric balloons have been used in obese patients to provide early satiety and thereby induce weight loss. Several studies have reported promising results with a new balloon (BIB((R))) designed to overcome some of the technical pitfalls of earlier devices. We assessed both safety and effectiveness of the BIB((R)). METHOD From November 2000(More)
The aim of this research was to determine the occurrence of epidermoid carcinoma of the esophagus induced by diethylnitrosamine (DEN) in Wistar rats. DEN was administered (250-300 g) in drinking water (10 mg/kg body weight) to four groups of rats for 72 h/week, for a duration of 90, 120, 150, or 200 days (groups T90, T120, T150, and T200). Ten animals whose(More)
Bleeding from esophageal varices is the major cause of death in patients with portal hypertension. The ideal surgical procedure should effectively control bleeding, with as little impairment of liver function as possible and with low rates of encephalopathy. Based on this objective, we propose the azygoportal disconnection (APD) with splenic artery(More)
BACKGROUND Binge-eating disorder (BED) may be associated with unsatisfactory weight loss in obese patients submitted to bariatric procedures. This study aims to investigate whether the presence of binge eating before Roux-en-Y gastric bypass (RYGBP) influences weight outcomes. METHODS In a prospective design, 216 obese patients (37 males, 178 females,(More)
A rare case of a 32-year-old male with situs inversus totalis viscerum admitted to hospital for hematemesis owing to portal hypertension of Laennec cirrhosis was treated for the first time by videolaparoscopic surgery. Situs inversus diagnosis was confirmed by thoracic radiography, electrocardiogram, echocardiogram, abdominal echography and computed(More)

Bariatric procedures increased in Brazil in the last decade. OBJECTIVES The purpose of this study was to verify if gender and age in date of procedure resulted significant(More)
Laparoscopic surgery, mainly laparoscopic cholecystectomy, is a recently developed surgical procedure that has rapidly gained acceptance. Its complications remain to be critically analyzed. In this initial series of 69 patients, the rate of complications was 4.3%, and the conversion to open rate was 8.7%. A late complication occurring 4 months after surgery(More)
BACKGROUND: -In recent decades, the high prevalence of obesity in the general population has brought serious concerns in terms of public health.
