A board\u2010certified radiologist, blinded to clinical and laboratory data, measured the duct diameter. A total of 893 patients (568 female and 325 male) were divided into 3 groups: group 1, remote cholecystectomy before sonography (mean, 9.7 years before sonography; n = 117); group 2, interval cholecystectomy between the first and second sonographic examinations (n = 56); and group 3, no cholecystectomy (n = 720). All groups were stratified by age, and group 3 was also stratified by the absence (n = 528) or presence (n=192) of gallstones.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Duct diameters at baseline and follow\u2010up averaged 4.5 and 5.2, 3.6 and 4.9, and 3.5 and 3.9 mm in groups 1, 2, and 3, respectively.

At follow\u2010up, group 2 ducts showed a greater interval diameter increase than the other groups (<jats:italic>P<\/jats:italic> &lt; .001). In a subanalysis of each group based on age, there was a mild increase in duct size with increasing age, although not clinically significant and within normal limits. In group 3 patients who never had gallstones, there was a significant small increase in duct size over decades (<jats:italic>P<\/jats:italic> &lt; .001).
