Band slippage--a potentially life-threatening complication after laparoscopic adjustable gastric banding

Although gastric bands are safe and effective devices, severe late complications may develop in rare cases. 3 patients were treated for complete dysphagia after slippage of gastric bands. 2 of the patients were admitted for severe dehydration, 1 of whom developed cerebral venous infarction. Ischemia of the gastric pouch occurred in 1 patient. All 3 patients survived after successful medical therapy and surgical removal of the bands. Bariatric reoperations were performed in 2 patients (gastric sleeve resection, gastric bypass). Complete dysphagia on the basis of band slippage represents a life-threatening acute event, which may occur even years after implantation. Patients and doctors should be informed about this long-term risk of gastric banding.
