Juxtapapil-lary duodenal diverticulum accounted for 24.55% ingroup Ⅰ, and only in 9.26% in group Ⅱ (P【0.05).Post-cholecystectomy patients were 13.64% in groupⅠ, and only 5.56% in group Ⅱ.Conclusions: The abnormalities of the distal commonbile duct and its surroundings can usually be detectedas underlying causes of common bile duct dilatation.ERCP is necessary before cholecystectomy, since it isconsidered the "gold standard" for the diagnosis ofdistal common bile duct abnormalities.展开更多
