LAGB is a technique increasingly used in the USA. The aim of this study is to analyze the 5-year outcome in terms of weight loss and complications. We reviewed our prospective electronic database for all patients undergoing LAGB between 2002 and 2007. We assessed weight progression, complications, and reoperations. We performed 199 cases during this period(More)
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is an emerging surgical technique with encouraging results. The objective of this study is to report surgical results after 1,000 consecutive LSG cases as a stand-alone procedure for morbid obesity during a 3-year follow-up. METHODS Data were obtained by review of our prospectively maintained database,(More)
Most large or fatal pulmonary embolisms (PE) at autopsy were unsuspected ante mortem. Newly identified clinical characteristics of PE enhance our ability to identify potential patients. Because of laudable efforts to diagnose PE, about 90% of outpatient computed tomographic (CT) angiograms are negative. Overuse of CT angiography has resulted in huge(More)
Portal and mesenteric vein thrombosis are relatively uncommon surgical complications, with difficult diagnosis and potentially severe consequences due to higher risk of bowel infarction. The purpose of this study was to present a series of patients who developed postoperative portal vein thrombosis after laparoscopic sleeve gastrectomy. This is a(More)
Colonoscopy is a safe and routinely performed diagnostic and therapeutic procedure for different colorectal diseases. Although the most common complications are bleeding and perforation, extracolonic or visceral injuries have also been described. Splenic rupture is a rare complication following colonoscopy, with few cases reported. We report a 60-year-old(More)
The duodenal-jejunal bypass sleeve (DJBS) has been shown to achieve a completely endoscopic duodenal exclusion without the need for stapling. This report is the first randomized controlled trial for weight loss. In a 12-week, prospective, randomized study, subjects received either a low fat diet and the DJBS or a low fat diet control (no device).(More)
The application of laparoscopic gastric surgery has rapidly increased for the treatment of early gastric cancer. However, laparoscopic gastrectomy for advanced tumor remains controversial, particularly in terms of oncologic outcomes. This study was designed to compare 3-year survival of laparoscopic versus open curative gastrectomy in early and advanced(More)
OBJECTIVE To evaluate safety, weight loss, and cardiometabolic changes in obese subjects implanted with the duodenal-jejunal bypass liner (DJBL) for 1 year. BACKGROUND The DJBL is an endoscopic implant that mimics the duodenal-jejunal bypass component of the Roux-en-Y gastric bypass. Previous reports have shown significant weight loss and improvement in(More)
Ankylosing spondylitis (AS) is a chronic inflammatory disease in which genetic factors play a central role. The efficacy of TNF blockers has reoriented research in this field in order to explain the influence of TNF in AS pathogenesis. The objective of this study was to access the influence of single nucleotide polymorphisms (SNPs) at positions -308 and(More)
