    Intraoperative ultrasound aids surgeons in visualizing the biliary tract, improving accuracy in locating the common bile duct and detecting gallstones. This real-time imaging helps reduce operative time during surgery.

    Area of Science:

    • Surgical Procedures
    • Medical Imaging
    • Gastroenterology

    Background:

    • Biliary tract surgery requires precise anatomical visualization.
    • Abnormal anatomy and inflammation can complicate surgical navigation.
    • Accurate detection of calculi (stones) is crucial for successful outcomes.

    Purpose of the Study:

    • To evaluate the utility of intraoperative B-mode ultrasound in biliary tract surgery.
    • To assess ultrasound's effectiveness in identifying common bile duct calculi and anatomical variations.
    • To determine if intraoperative ultrasonography can improve surgical efficiency.

    Main Methods:

    • High-resolution real-time B-mode ultrasound scanning was employed.
    • A sterile 7.5 MHz transducer was used during operations.

  • Ultrasound was utilized for anatomical localization and calculi detection.

    • Main Results:

    • Ultrasound effectively located the common bile duct amidst inflammation and abnormal anatomy.
    • Small gallbladder calculi and common bile duct calculi were accurately detected.
    • Ultrasound enabled precise measurement of the common bile duct's caliber.

    Conclusions:

    • Intraoperative ultrasonography enhances the appraisal of operative findings in biliary tract surgery.
    • The use of ultrasound can lead to earlier and more precise surgical decisions.
    • Employing intraoperative ultrasound may decrease overall operative time.
