title: [Gastric bypass in the surgical treatment of extreme adiposity].
abstract: The gastric bypass is an effective surgical procedure for the treatment of extreme obesity. A small gastric reservoir and a narrow anastomosis are combined (to limit the possibility of food intake). In patients with a mean weight of 94% above the Broca value the normal weight is reached 18 months after the operation. Failure to lose weight can be caused by technical errors during the procedure or by a continuous food intake by the patients. Surgical complications are rare. The operative lethality is less than 1%, and anastomotic ulcers occur in 2% of cases. There is no reason to expect metabolic derangements as after jejunoileal bypass.
