Intraoperative ultrasonography effectively detects biliary calculi, including common bile duct stones, with high accuracy. This imaging technique aids in diagnosing choledocholithiasis, especially in challenging cases involving intrahepatic ducts or distal common bile duct stones.

Area of Science:

  • Gastroenterology
  • Surgical Imaging
  • Hepatobiliary Surgery

Background:

  • Biliary calculi, or gallstones, are a common clinical problem.
  • Accurate intraoperative detection of common bile duct stones is crucial for successful surgical outcomes.
  • Distinguishing between distal common bile duct stones and neoplastic changes can be challenging.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of intraoperative ultrasonography in detecting biliary calculi.
  • To compare the efficacy of intraoperative ultrasonography with operative cholangiography.
  • To identify specific scenarios where ultrasonography offers advantages in diagnosing choledocholithiasis.

Main Methods:

  • A retrospective analysis of 55 patients undergoing surgery for biliary calculi.

  • Intraoperative ultrasonography of the biliary tree was performed in all patients.
  • Operative cholangiography was utilized in select cases for comparison.

    • Main Results:

    • Intraoperative ultrasonography demonstrated high accuracy in diagnosing choledocholithiasis: sensitivity 84.21%, specificity 100%, efficiency 94%.
    • The accuracy of intraoperative ultrasonography was comparable to operative cholangiography when both were performed.
    • Ultrasonography showed particular utility in cases of intrahepatic duct lithiasis and distal common bile duct stones, facilitating differentiation from neoplastic conditions.

    Conclusions:

    • Intraoperative ultrasonography is a reliable and accurate tool for detecting biliary calculi, including common bile duct stones.
    • Its high specificity and efficiency make it valuable for intraoperative decision-making.
    • Ultrasonography offers superior diagnostic capabilities in complex cases, such as intrahepatic lithiasis and distal common bile duct stones, improving the differentiation from malignant conditions.
