title: Studies on the effect of small bowel bypass for massive obesity on gastric secretory function.
abstract: Gastric secretory function was studied in 20 morbidly obese patients both before and after jejuno-ileal bypass. The mean postoperative weight loss was 99.2 pounds during a mean postoperative followup period of 12.6 months. The gastric secretory values we studied included basal and histalogstimulated volume, pH, concentration, and output. No statistically significant changes were observed in any of these variables. Therefore it is suggested that jejuno-ileal bypass, as performed for morbid obesity, is probably not an ulcerogenic procedure.
