    Abstract:
    Biliopancreatic bypass for obesity entails a 2/3 distal gastrectomy with Roux-en-Y reconstruction, being the small bowel transected at its midpoint and the enteroenteroanastomosis placed 50 cm proximal to the ileocecal valve. Insulin and GIP fasting and meal-stimulated plasma concentrations were determined in 13 nonobese healthy volunteers, in 13 nonoperated obese patients, in 11 subjects within two months, in 12 subjects four to twelve months, and in 7 subjects fifteen to twenty months after operation. Insulin in the obese patients was significantly higher than in the control group. Postoperatively these patients showed a sharp reduction in basal and postprandial values. Plasma insulin levels, both basally and following the test meal, were very similar in the 15-20 month and the control group. Plasma GIP fasting level, meal-stimulated peak and integrated response in the obese group were higher than in control group. Due to the extreme variability among subjects in the obese group, the difference was significant only for the mean peak response. All values were greatly reduced after surgery. The mean fasting level in the 15-20 month group was very similar to that in the control group, and both peak and integrated responses were significantly lower than in the preoperative and control groups.
