Gastric volvulus after laparoscopic adjustable gastric banding for morbid obesity.

摘要

Since it was approved for the management of morbid obesity in the United States in 2001 , laparoscopic adjustable gastric banding has become an increasingly popular form of bariatric surgery. Some surgeons favor laparoscopic adjustable gastric banding over Roux-en-Y gastric bypass because it is a less invasive procedure with a lower morbidity and mortality [1, 2]. Nevertheless, laparoscopic adjustable gastric banding can have a variety of serious postoperative complications that do not occur with more traditional bariatric procedures. These complications include stomal stenosis with pouch dilatation, band slippage and gastric prolapse, band erosion, chronic gastric perforation, and, rarely, gastric volvulus [1-4]. Although it is a potentially life-threatening condition, gastric volvulus as a complication of laparoscopic adjustable gastric banding has received little attention in the radiology literature [5j. We encountered two patients who had undergone laparoscopic adjustable gastric banding in whom band slippage precipitated gastric volvulus that was detected on barium studies, necessitating emergency surgical removal of the bands. We report our experience with these patients.
