Fate of weight. Ten-year observations after jejunoileal bypass for obesity.

In 182 patients weight results up to ten years after various types of jejuno-ileal bypass for obesity are presented. Initially end-to-end operated patients had a significantly greater weight loss than end-to-side operated but the significance disappeared from six years and on. Five years after the operation 19% of the patients were still losing weight. Mean weight loss after this time was 33% and 36% of the patients had a body weight at or below Broca's index 1.25 which is considered excellent or good. Median regain of lost weight was 22% five years after minimum.
