We included 30 obese normal glucose-tolerant (NGT) subjects, 32 obese subjects with T2DM, and 12 lean female subjects. Obese subjects underwent either a restrictive procedure (gastric banding [GB], a very low-calorie diet [VLCD]), or a restrictive/bypass procedure (Roux-en-Y gastric bypass [RYGB] surgery). Fasting blood samples were taken for the determination of amine group containing metaboli...

BACKGROUND The use of bariatric surgery in the management of morbid obesity is rapidly increasing. The two most frequently performed procedures are laparoscopic Roux-en-Y bypass and laparoscopic gastric banding. The objective of this short overview is to provide a critical appraisal of the most relevant scientific evidence comparing laparoscopic gastric banding versus laparoscopic Roux-en-Y byp...

HYPOTHESIS After gastric bypass surgery performed because of morbid obesity, the excluded stomach can rarely be endoscopically examined. With the advent of a new apparatus and technique, possible mucosal changes can be routinely accessed and monitored, thus preventing potential benign and malignant complications. DESIGN Prospective observational study in a homogeneous population with nonspeci...

Gastro-gastric fistula is a communication between the gastric remnant and gastric pouch. It is a rare complication of Roux-en-Y gastric bypass. It is caused by anastomotic leak, marginal ulcers, distal obstruction or erosion from foreign body. In this case report, we are presenting a successful laparoscopic repair of gastro-gastric fistula in a patient who presented with weight gain after initi...

BACKGROUND Currently, bariatric surgery is the most effective therapy for morbid obesity, and the laparoscopic approach is considered gold-standard for Roux-en-Y gastric bypass. Totally robotic Roux-en-Y gastric bypass has been proposed as a major evolution in minimally invasive bariatric surgery and its use is becoming more widespread. AIM To provide an early report of the first Brazilian ca...

This article describes the use of gastric bypass surgery for severe gastroparesis in two lung transplant recipients. In addition to feeding intolerance, both our patients suffered from severe erosive esophagitis, transfusion-dependent upper GI hemorrhage, and recurrent aspiration pneumonia. They responded poorly to promotility agents and were eventually treated with Roux-en-Y esophagojejunostom...

BACKGROUND Gastric bypass operation has become a very common procedure for treatment of obesity. Changes in calcium absorption can result in changes in total body calcium, parathyroid hormone (PTH), and vitamin D levels. There is little known about the longterm effects of Roux-en-Y gastric bypass on calcium metabolism and bone homeostasis. STUDY DESIGN Between January 2000 and January 2006, 5...

BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most commonly performed bariatric surgical procedures. A laparoscopic gastric bypass is associated with specific complications: internal herniation is one of these. CASE REPORT A 47-year-old woman had undergone a laparoscopic Roux-en-Y gastric bypass (LRYGB) 18 months before presentation at our emergency department with mi...

Abdominal contouring procedures are frequently performed following massive weight loss after a Roux-en-Y gastric bypass. This last procedure can be associated with late complications like the development of internal hernias (e.g., Petersen hernia). The purpose this article is to present case hernia complete abdominoplasty. A 42-year-old female presented emergency department acute abdominal pain...
