    Summary

    Identifying common bile duct stones requires careful evaluation. Prompt diagnosis and meticulous surgical exploration, followed by cholangiography, are crucial to prevent retained stones and minimize patient morbidity.

    Area of Science:

    • Gastroenterology
    • Hepatobiliary Surgery
    • Diagnostic Imaging

    Background:

    • Choledocholithiasis, or stones in the common bile duct, presents diagnostic challenges.
    • Retained stones post-exploration lead to significant patient morbidity.

    Purpose of the Study:

    • To identify key diagnostic indicators for choledocholithiasis.
    • To reduce the incidence of retained common bile duct stones after surgical exploration.

    Main Methods:

    • Retrospective review of 110 patients undergoing common bile duct exploration.
    • Analysis of clinical presentation, laboratory values, operative findings, and cholangiography results.

    Main Results:

    • Cholangitis and jaundice were strongly associated with choledocholithiasis.

  • Elevated serum bilirubin (>6 mg/dl) and alkaline phosphatase (>250 IU) were significant indicators.
  • Operative cholangiography and palpation of stones confirmed diagnosis; small gallstones with a dilated cystic duct were suggestive.
  • Careful exploration and T-tube cholangiography prevented stone retention.
  • Nonoperative radiologic extraction is effective for retained stones but carries morbidity.

    • Conclusions:

    • Clinical signs like jaundice and cholangitis, alongside specific laboratory thresholds, aid in diagnosing choledocholithiasis.
    • Meticulous surgical technique and intraoperative cholangiography are essential for preventing retained stones.
    • Nonoperative management of retained stones is viable but associated with complications.
