    Summary
    This summary is machine-generated.

    Routine intraoperative biliary endoscopy significantly reduces missed common bile duct stones. This technique, even when performed by supervised residents, improves patient outcomes in benign biliary disease surgery.

    Area of Science:

    • Gastroenterology
    • Surgical Endoscopy
    • Biliary Tract Surgery

    Background:

    • Missed biliary calculi (stones) are a common complication after common bile duct exploration.
    • Intraoperative biliary endoscopy is not universally adopted, leading to variations in stone detection rates.

    Purpose of the Study:

    • To evaluate the incidence of missed biliary calculi in a teaching hospital utilizing routine intraoperative biliary endoscopy.
    • To compare the efficacy of choledochoscopy in detecting retained stones versus traditional methods.

    Main Methods:

    • A retrospective analysis of 1,280 procedures for benign biliary disease over six years.
    • Choledochoscopy using a rigid endoscope was performed in 148 patients undergoing common duct exploration.
    • Follow-up T-tube cholangiograms were used to assess for retained stones.

    Main Results:

    • Choledocholithiasis was found in 152 of 208 patients (73%) undergoing common duct exploration.
    • When choledochoscopy was employed, the incidence of missed stones on follow-up cholangiogram was only 2.3%.
    • This rate is lower than reported series not using intraoperative choledochoscopy.

    Conclusions:

    • Routine intraoperative biliary endoscopy is effective in reducing the rate of retained common bile duct stones.
    • The technique is beneficial even when performed by supervised surgical residents with limited specialized training.
    • Routine use of intraoperative biliary endoscopy is recommended for all patients undergoing common duct exploration.
