Near-total gastric bypass for morbid obesity.
Among 50 morbidly obese patients who underwent gastric bypass, the gastric pouch was made only large enough to permit an anastomosis with the jejunum. Eighteen months after operation, the mean weight loss was 55 kg, and the mean excess weight loss was 70%. One half of the patients had less than 22.7 kg of residual excess weight. The most frequent immediate postoperative complication involved the respiratory tract (ten patients). Staple line failure in three of ten patients who had pouch construction by a single application of staples and iron deficiency anemia in six patients were the most important late complications. Near-total gastric bypass in which the pouch is constructed with two applications of staples is an effective operation for weight control and should virtually eliminate the need for revision caused by staple line failure or for a pouch that is too large.
