“…We conducted our study to investigate if cholecystectomy status, age, and sex had measurable impacts on the diameter of the extrahepatic BD. Most studies to date have investigated BD diameters in patients planned to undergo cholecystectomy for cholecystitis [7,8,10,11,13,27,28]. This approach suffers from selection bias and cannot show if the effects on the BD diameter result from cholecystectomy or the underlying obstruction of the BD.…”

“…More importantly, the magnification effect of x rays may increase the margin of error of measurement 14. A comparison of bile duct diameter in post-cholecystectomy patients undergoing ERCP with controls15 suggested that the post-cholecystectomy bile ducts may be wider than normal; however, this study did not examine the patients preoperatively and did not take into account the possible increased distensibility of the common duct after cholecystectomy,16 17 which may be accentuated during injection at ERCP.…”

Background-The common hepatic duct (CHD) is commonly believed to dilate after cholecystectomy but previous studies have either not measured CHD diameter preoperatively or the follow up period is short. Aims-To measure CHD diameter before and after cholecystectomy. Methods-Patients undergoing (open)cholecystectomy and operative cholangiography had ultrasonographic measurement of CHD diameter before, and three and six months, and one and five years after cholecystectomy. The normal duct diameter was considered to be 5 mm or less, with an observer error of ±1 mm. Results-Fifty nine patients with normal diameter ducts were studied. The majority (more than 95%) of patients did not have a dilatation of the CHD beyond 6 mm after cholecystectomy. The CHD appeared to increase as well as decrease with an overall trend towards a minor increase at five years. This was not statistically significant if the margin of error of 1 mm was taken into account. Conclusion-A preoperatively normal CHD does not dilate after cholecystectomy and may require further investigation in symptomatic patients. (Gut 1999;45:741-743)
