The only effective treatment for patients with morbid obesity is surgery. Laparoscopic bariatric surgery has become quite popular in attempts to decrease the morbidity associated with laparotomy. In this article, we describe the technical details of laparoscopic Roux-en-Y gastric bypass with three different techniques for creating the 15-cc gastric pouch. These techniques avoid upper endoscopy ...

Achalasia is a rare esophageal motility disorder that is characterized by a loss of peristalsis in the distal esophagus and failure of lower esophageal sphincter relaxation. The risk of developing esophageal motility disorders, including achalasia, following bariatric surgery is controversial and differs based on the type of surgery. Most of the reported cases occurred with laparoscopic adjusta...

CONTEXT Causal factors of gastrojejunal ulcers after Roux-en-Y gastric bypass include peptic acid secretion from the gastric pouch. Esomeprazole is a potent inhibitor of acid secretion. OBJECTIVE To assess the occurrence of dyspepsia and gastrojejunal ulcers within the first 2 months after Roux-en-Y gastric bypass during the use of esomeprazole. METHODS One hundred eighteen morbid obese sub...

Worldwide, there have been <25 reported cases of hyperammonemic encephalopathy associated with Roux-en-Y gastric bypass surgery in the absence of cirrhosis. We describe a 42-year-old woman who presented with subacute but progressive neurological decline late in her postoperative course, which deteriorated despite multiple conservative and aggressive measures, including hemodialysis, in an attem...

Postprandial symptoms of neuroglycopenia after bariatric surgery may result as a consequence of endogenous hyperinsulinemic hypoglycemia (nesidioblastosis) not dumping syndrome. Pancreatectomy is an acceptable treatment for this condition. We present the video of a case of near-total distal robotic pancreactectomy for the treatment of nesidioblastosis after Roux-en-Y gastric bypass. Robotic pan...

Laparoscopic gastric bypass is becoming a frequently performed bariatric operation for patients with obesity. However, bariatric surgery has inherent risks and complications, which are further potentiated by the high risk nature of bariatric patients. These complications can be either site specific i.e. anastomotic leaks, or systemic i.e. venous thromboembolism, however they can intimately rela...

OBJECTIVES Roux-en-Y gastric bypass surgery is the most commonly performed procedure for the treatment of morbid obesity. This anatomical alteration may affect the absorption and consequently the bioavailability of oral drugs. This study aims to investigate the oral bioavailability of moxifloxacin in 12 healthy volunteers who underwent gastric bypass surgery. PATIENTS AND METHODS In this rand...

OBJECTIVE To evaluate the effects of two bariatric procedures versus intensive medical therapy (IMT) on β-cell function and body composition. RESEARCH DESIGN AND METHODS This was a prospective, randomized, controlled trial of 60 subjects with uncontrolled type 2 diabetes (HbA1c 9.7 ± 1%) and moderate obesity (BMI 36 ± 2 kg/m(2)) randomized to IMT alone, IMT plus Roux-en-Y gastric bypass, or I...

OBJECTIVE To assess obstetrical and neonatal outcomes in women following gastric bypass, compared with adipose women without surgery and with a normal weight control population. DESIGN Historical controlled cohort study. SETTING Denmark. POPULATION All women undergoing gastric bypass during the period 1996-2011, and subsequently giving birth. METHODS AND MAIN OUTCOME MEASURES Obstetrica...
