Intestinal bypass surgery for morbid obesity. Long-term results
L. T. DeWind and J. H. Payne
Since 1962, jejunoileal bypass has been performed on 59 male and 171 female
subjects, aged 18 to 55 years; these patients were followed clinically.
Postoperative weight loss at two years averaged 37% in men and 35% in
women. Hypokalemia (23%), hypocalcemia (22%), hypoalbuminemia (9%),
metabolic acidosis (14%), elevated liver enzyme values (41%), and
hyperbilirubinemia (6%), were the most commonly encountered blood chemical
alterations. Complications were arthritis syndrome (men, 8%; women, 19%).
urinary calculi (men, 24%; women, 10%), cholelithiasis (men, 10%; women,
9%), liver impairment (men, 2%; women, 6%), and major emotional upset (men,
8%; women, 9%). Forty-nine percent of the men and 51% of the women required
rehospitalization for management of complications, surgery for hernia,
anorectal disorders, nutritional support, and metabolic study. There were
19 bypass-related deaths (8%), including 10 due to liver failure.
