This report describes a rare case of adult intussusception in a patient with a history of a Roux-en-Y gastric bypass procedure; complicated by a history of narcotic abuse, methadone dependence, and methamphetamine abuse. Adult patients who have undergone a Roux-en-Y gastric bypass procedure may be at an increased risk of developing intussusception, and clinicians involved in their care should b...

of evidence • Patients undergoing various bariatric surgical procedures lost an average of 61.2% of their excess weight (varying from 47.5% for gastric banding to 70.1% for biliopancreatic diversion or duodenal switch procedures) • Perioperative mortality was relatively low (varying from 0.1% for banding, 0.5% for bypass, to 1.1% for biliopancreatic diversion or duodenal switch) • Most patients...

Bowel obstruction is a known complication of Roux-en-Y gastric bypass. It can be caused by adhesions, internal hernia, incarcerated ventral hernia, or intussusception. Sometimes the underlying cause may be unusual. These 2 case reports describe patients who underwent laparoscopic Roux-en-Y gastric bypass and whose postoperative courses were complicated by small-bowel obstruction due to phytobez...

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...

This paper discusses the application of Peroral Endoscopic Myotomy (POEM) in treatment achalasia post-bariatric patients. Achalasia is an esophageal motility disorder characterized by malfunction lower sphincter (LES) and aperistalsis. POEM has emerged as a promising less invasive technique for this condition, particularly patients with previous bariatric surgery. We present two cases successfu...

creating a ‘‘temporary bypass’’ of the fistula. Other proposed treatments include the endoscopic use of adhesives (surgical glues),which has provided controversial results. In cases that do not respond to any treatment, the possibility of treating the distal stenosis (if there is any) with endoscopic dilatations should be assessed. If there is no other option left except for surgery, simple fis...

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...

A 57-year-old woman, who had undergone Roux-en-Y gastric bypass surgery 9 years earlier, was admitted to the intensive care unit because of pneumonia. Despite antibiotic therapy, she died 40 days later, apparently because of sepsis and organ failure related to the pneumonia. However, the patient's family requested an autopsy, which revealed that her death was due to perforation of the Roux limb...

A 44-year-old woman underwent gastric bypass surgery in 2004. One year later, she began to complain of intermittent melena associated with nausea and right upper quadrant (RUQ) pain, which required 1 to 2 units of packed red blood cell transfusions per year. In July 2007, she presented to the emergency department with 2 episodes of bright red blood per rectum associated with syncope. Upper endo...
