Laparoscopic management of gastric perforation secondary to mesenteroaxial volvulus in a patient with laparoscopic adjustable gastric banding.

A 54-year-old woman was admitted to the emergency department with a 2-week history of alimentary vomiting. She had undergone laparoscopic adjustable gastric banding 6 years earlier. CT revealed a mesenteroaxial gastric volvulus and ischemia on the gastric wall. Emergent diagnostic laparoscopy was performed, and severe peritonitis and gastric necrosis caused by volvulation was found. After band removal, a fundal perforation was noted, but a viable lesser curvature enabled laparoscopic sleeve gastrectomy to be performed. The postoperative course was uneventful. Laparoscopic adjustable gastric banding is considered a safe and effective method for the surgical treatment of obesity, but it is associated with a number of complications, such as pouch dilatation and band slippage. Although infrequent, ischemic complications are life-threatening conditions that require urgent surgery. This is the first report of this unusual complication managed laparoscopically.
