The role of cholecystectomy and transduodenal sphincteroplasty on duodenogastric reflux (DGR) is still controversial. PURPOSE--To assess the effect of cholecystectomy alone, transduodenal sphincteroplasty alone and cholecystectomy combined with transduodenal sphincteroplasty on bile reflux into the stomach. METHODS--40 dogs were divided into four groups: control group (C) (n = 12), cholecystectomy group (Co) (n = 10), transduodenal sphincteroplasty group (Es) (n = 10) and cholecystectomy plus transduodenal sphincteroplasty group (Co+Es) (n = 8). A quantitative index of DGR was obtained in each case by determining the percentage of the intravenously injected 99m Technetium-DISIDA that was recovered in the gastric juice. RESULTS--The DGR was significantly higher in Co+Es group (mean: 2.26 +/- 2.69%) than in the C group (mean: 0.23 +/- 0.26%), and the Co group (mean: 1.52 +/- 1.77%) and the Es group (mean: 1.23 +/- 1.23%) (p < 0.05). The DGR did not differ significantly between C, Co and Es groups (p > 0.05). CONCLUSION--The results shows that only cholecystectomy plus sphincteroplasty increases duodenogastric reflux.
