Surgical treatment of esophageal cancer is associated with a high rate of morbidity and mortality even in specialized centers. Minimally invasive surgery has been proposed to decrease these complications. The authors present their results regarding postoperative complications and the survival rate at 3 years, comparing the classic open procedures(More)
BACKGROUND One of the most serious complications after laparoscopic sleeve gastrectomy (LSG) is gastric leak. Few publications exist concerning the treatment of gastric leak. We sought to determine by way of a prospective study the clinical presentation, postoperative course, and treatment of gastric leak after LSG for obesity. METHODS From October 2005(More)
The diagnosis of Barrett's esophagus is based on the presence of intestinal metaplasia (IM) at the distal esophagus. The aim of this study was to determine the prevalence of IM in patients with symptoms of gastroesophageal reflux in whom endoscopically a segment of distal esophagus was covered by columnar epithelium (CE). In a prospective, descriptive and(More)
Sterol receptor element-binding protein-1c (SREBP-1c) and peroxisome proliferator-activated receptor-alpha (PPAR-alpha) mRNA expression was assessed in liver as signaling mechanisms associated with steatosis in obese patients. Liver SREBP-1c and PPAR-alpha mRNA (RT-PCR), fatty acid synthase (FAS) and carnitine palmitoyltransferase-1a (CPT-1a) mRNA(More)
BACKGROUND The classic surgical procedure for patients with Barrett's esophagus (BE) has been either Nissen fundoplication or posterior gastropexy with calibration of the cardia. METHODS The purpose of our study was to determine late subjective and objective results of these classic surgical techniques in a large number of patients with BE. A total of 152(More)
BACKGROUND The aim was to perform a prospective randomized study in patients with chronic gastro-oesophageal reflux treated either by total fundoplication or calibration of the cardia with posterior gastropexy. Late follow-up considered subjective and objective parameters, and related outcome to the presence of Barrett's oesophagus. METHODS A total of 164(More)
INTRODUCTION Laparoscopic esophagomyotomy is the preferred approach to patients with achalasia of the esophagus, However, there are very few long-term follow-up studies (>10 years) in these patients. OBJECTIVE To perform a very late subjective and objective follow-up in a group of 67 patients submitted to esophagomyotomy plus a partial antireflux surgery(More)
BACKGROUND Sleeve gastrectomy (SG) has been accepted as an option for surgical treatment for obesity. This operation could be associated with motor gastric dysfunction and abnormal gastric emptying. The purpose of this prospective study is to present the results of gastric emptying to liquids and solids using scintigraphy in patients who underwent SG(More)
BACKGROUND Sleeve gastrectomy is a restrictive procedure for treatment of obese patients with different body mass index (BMI) and presents good results in terms of a reduction of percentage of excess weight loss and BMI. There is no consensus which is the optimal technique regarding to the diameter of the gastric tube, but a capacity of 100-120 ml has been(More)
In a prospective endoscopic and bioptic study, 141 control subjects and 359 patients with symptoms of gastroesophageal reflux (GER) were included to determine the prevalence of cardial epithelium inflammation or 'carditis' and to determine the prevalence of Helicobacter pylori in this area. Two biopsies at the antrum, four distal to the squamous-columnar(More)
