Patients undergoing Roux-Y hepaticojejunostomy showed a significant increase in maximum acid output at follow-up, although only one case of peptic ulcer was observed. In addition, the frequency of cases showing gastric acid hypersecretion was higher than for jejunal interposition hepaticoduodenostomy. Two kinds of test meals (carbohydrate-rich or fat-rich) were given, on different days, to each patient before and about four weeks after surgery. Plasma concentrations of gastrointestinal hormones and glucose or triglyceride were determined. Fasting concentrations of gut hormones (gastrin, GIP, insulin and GLI) were similar to those before surgery, and increased after the ingestion of the test meals. Gastrin and total GLI levels tended to be higher in the Roux-Y than in the interposition group, and vice versa for both insulin and GIP.
The changes in plasma glucose and triglyceride, following the Roux-Y procedure, suggest disturbances in carbohydrate tolerance, fat digestion, and in the anabolic phase of absorbed fat. Patients undergoing the Roux-Y procedure should be carefully followed up, since gastric acid hypersecretion induced by a postprandial augmented release of gastrin was observed.
