Abstract

The effect of cholecystectomy on common bile duet diameter remains controvertial, It has been shown that the diameter of common bile duet increases significantly in the early postoperative period, but in the long term studies such on evidence has not been shown. This study investigates the long term changes in the diameter of common bile duet ond its relationship with symptomatic relief following cholecystectomy. Twenty eight patients undergoing elective open or laparoscopic cholecystectomy due to symptomatic gall blodder stone were studied. The common bile duct diameter of these patients were measured by ultrasonography and compared with the preoperative values. Meanwhile the degree of symptomatic improvement was determined by a guestionnaire to compare the preoperative and postoperative symptoms. The median follow-up period was 98.5 (53-135) months. In the postoperative measurements, the diameter of common bile duet was found to be more than 7 mm in 29% of the patients (mean 6.1 mm) where as the corresponding figure was 43%, preoperotively (mean 7.4 mm). There was no statistically significant difference in measurements between two periods. Following cholecystectomy, 79% of patients had complete symptomatic relief. All patients were satisfied with the operation in various degrees. As the conclusion, cholecystectomy has no effect on changes of common bile duet diameter and clinical success as well as patient satisfaction can be achieved when patients with appropriate indication are chosen for surgery.
