Laparoscopic intracorporeal ultrasound (LICU) aids in diagnosing liver tumors and defining hepatobiliary anatomy during surgery. This minimally invasive technique accurately identifies common bile duct stones and aids in pancreatic cancer staging.

Area of Science:

  • Minimally Invasive Surgery
  • Medical Imaging
  • Gastroenterology

Background:

  • Ultrasonography offers diverse clinical applications via external and internal methods.
  • Advancements in transducer miniaturization enable intracorporeal ultrasound during laparoscopy.

Purpose of the Study:

  • To present the principles of ultrasonography.
  • To evaluate the utility of laparoscopic intracorporeal ultrasound (LICU) in surgical diagnostics and anatomy delineation.

Main Methods:

  • Review of ultrasonography principles.
  • Application of LICU in laparoscopic procedures for liver tumor diagnosis, hepatobiliary anatomy assessment, and common bile duct stone detection.

Main Results:

  • LICU demonstrated high accuracy in identifying suspected liver tumors (75/85 patients).

Related Experiment Videos

  • LICU provided valuable anatomical information during laparoscopic cholecystectomy and accurately detected common bile duct stones.
  • LICU showed potential in preoperative staging of pancreatic malignancy.

    • Conclusions:

    • Laparoscopic intracorporeal ultrasound is a valuable tool for liver tumor diagnosis and surgical guidance.
    • LICU enhances the safety and accuracy of laparoscopic procedures, particularly in hepatobiliary surgery.
    • Further applications of LICU are anticipated as surgical experience grows.
