BACKGROUND/AIMS: The well-organized study to support that increased @entity2963 and bile duct dilatation can occur after gastrectomy has not been reported. The aim of this study was to determine the incidence of @entity2963 and the degree of common bile duct (CBD) dilatation in @entity1 undergoing subtotal gastrectomy, compared to those undergoing endoscopic treatment for @entity356 . METHODS: @entity1 who diagnosed with @entity356 and received treatment at six academic referral centers were investigated for the incidence and time of @entity2963 and the degree of @entity1157 after treatment by analysis of 5-year follow-up CTs. The operation group underwent subtotal gastrectomy without vagotomy, while in the control group endoscopic treatment was administered for @entity356 . RESULTS: A total of 802 @entity1 were enrolled in 5-year analysis (735 @entity1 in the operation group and 67 @entity1 in the control group). @entity2963 occurred in 47 @entity1 (6.39%) in the operation group and 3 @entity1 (4.48%) in the control group (p=0.7909). The incidences of @entity2963 were 4.28% in Billoth-I and 7.89% in Billoth-II (p=0.0487). The diameter of proximal CBD and distal CBD increased by 1.11 mm and 1.41 mm, respectively, in the operation group, compared to 0.4 mm and 0.38 mm, respectively, in the control group (p  0.05). @entity1 with increased @entity1157 more than 5 mm showed statistically significant increases in alkaline phosphatase and gamma-glutamyltransferase. CONCLUSIONS: The incidence of @entity2963 was not increased due to subtotal gastrectomy without vagotomy, but the incidence was higher after Billoth-II compared to Billoth-I. In addition, significant change in the CBD diameter was observed after subtotal gastrectomy.
