Gastric and Jejunoileal Bypass

Abstract

Two series of bypass operations performed to bring about weight reduction in morbidly obese patients are compared. The same criteria determined patient selection, and all patients were operated on and followed up by the same surgeon. The first group of 100 patients underwent a 14-4 jejunoileostomy, and the second group of 100 underwent a modification of the gastric bypass procedure, in which 90% of the stomach is bypassed. The safety and operating time of the two operations were about equal, but long-term complications of the jejunoileal bypass were greater in frequency, duration, and seriousness. For this reason, the modified gastric bypass described here is preferred.
