Purpose: To evaluate @entity51045 ( @entity51045 ) dilation by computed tomography (CT) in @entity1 with intact gallbladders and diameter change over time in remote and interval cholecystectomy @entity1 , frequency of visualization of the @entity51045 , and its relationship to age. Methods: This IRB-approved retrospective study evaluated baseline @entity51045 diameter, intrahepatic @entity384 , and interval duct diameter change in @entity1 with CTs  >=   2  years apart (n  =  324), in block-randomized order by two blinded board-certified radiologists. 272 @entity1 were divided into three groups: (1) prior cholecystectomy before the first CT, (2) cholecystectomy between the first and last CTs, and (3) no cholecystectomy. A subset of 191 nonoperated @entity1 was evaluated for age-related dilation. Results: Group 1 ducts were significantly larger than the other groups at both baseline and follow-up CTs (p  <  0.001). Group 2 showed a greater increase in duct size than the other groups at follow-up (p  <  0.001). The @entity51045 was measurable in 89% of the CT studies. In nonoperated @entity1 , there was a statistically significant correlation between @entity51045 size and increasing age (p  <  0.001), although the @entity51045 size remained within normal size limits. Conclusion: Remote cholecystectomy @entity1 have larger @entity51045 diameters than the nonoperated and interval cholecystectomy groups. Greater increase in ductal diameter occurred between studies in the interval cholecystectomy @entity1 , suggesting that dilation occurs after cholecystectomy. Also, the @entity51045 dilates slightly with age in nonoperated @entity1 .
