Area of Science:

  • Minimally Invasive Surgery
  • Diagnostic Imaging
  • Surgical Oncology

Background:

  • Laparoscopic surgery offers numerous benefits but requires effective intraoperative visualization.
  • Assessing biliary tree pathology and detecting malignancy during laparoscopy presents challenges.
  • Traditional methods like cholangiography have limitations.

Purpose of the Study:

  • To introduce and evaluate the efficacy of laparoscopic ultrasonography (LUS) in a prospective surgical setting.
  • To assess LUS as an alternative to cholangiography for common bile duct (CBD) pathology.
  • To explore the utility of LUS in evaluating abdominal malignancies.

Main Methods:

  • A prospective study involving 37 patients undergoing laparoscopic surgery.
  • Utilized an Aloka SSD 2000 mobile scanner with a flexible linear-array transducer and Doppler capabilities.

  • LUS was frequently employed during laparoscopic cholecystectomy and in cases of suspected malignancy.

    • Main Results:

    • LUS was successfully performed in all cases, visualizing the distal CBD (89.2%) and common hepatic duct (97.3%).
    • Identified biliary disorders in 6/27 cholecystectomy cases, including CBD stones.
    • Demonstrated high visualization quality (83.8% very good) and effective use of Doppler for structure differentiation.
    • Accurately excluded liver metastasis in a colon cancer case.

    Conclusions:

    • LUS integrates diagnostic laparoscopy with intraoperative ultrasonography advantages.
    • It is a simple, efficient, and recommended technique for intraoperative CBD exploration.
    • LUS enhances abdominal malignancy assessment, potentially altering therapeutic strategies.
    • Color Doppler mode aids surgeons in complex surgical directions.
