  • Title: Assessing the role of routine choledochoscopy during exploration of the bile duct.
    Author: Scher KS, Gardner SA, Peoples JB.
    Journal: Surg Gynecol Obstet; 1990 Jul; 171(1):9-12. PubMed ID: 2360158.
    Abstract:
    Two hundred and five consecutive explorations of the common bile duct were evaluated to assess the value of routine choledoschoscopic examination in preventing retained stones. Conventional exploration was performed in 139 instances (group 1), while routine choledochoscopy was added in 66 procedures (group 2). Preoperative temperature, leukocyte count, total bilirubin, amylase and alkaline phosphatase levels were not significantly different between the groups. Nine retained stones were demonstrated by postoperative cholangiography among the patients in group 1 as compared with three retained stones noted in those in group 2. This difference was not significant. Postoperative mortality and complication rates were unaffected by the performance of an endoscopic study of the biliary tract during ductal exploration. Choledochoscopy added an average of 36 minutes to the duration of the operative procedure (p less than 0.001). Choledochoscopy may prove helpful in selected instances, but the current data do not support its routine use during exploration of the common bile duct.
