Segmental liver resection in pigs using a linear stapling device was found to be a safe and quick alternative to the conventional finger fracture technique. This method offers potential benefits for hepatic resection procedures.

Area of Science:

  • Veterinary Surgery
  • Surgical Techniques
  • Comparative Surgical Analysis

Background:

  • Segmental liver resection is a common surgical procedure.
  • Conventional techniques like finger fracture can be time-consuming and may lead to complications.
  • Evaluating alternative methods for hepatic resection is crucial for improving surgical outcomes.

Purpose of the Study:

  • To compare the efficacy and safety of linear stapling device resection versus conventional finger fracture technique for segmental liver resection in pigs.
  • To assess operative time, specimen weight, postoperative hemoglobin levels, and blood loss.
  • To evaluate the incidence of bile leakage and postoperative bleeding.

Main Methods:

  • 14 pigs underwent segmental liver resection.

  • Animals were randomized to either conventional finger fracture technique or linear stapling device (TA-90R) resection.
  • Postoperative outcomes including blood loss, hemoglobin levels, and post-mortem examinations were assessed.

    • Main Results:

    • The linear stapling device group showed a trend towards shorter resection times, though not statistically significant.
    • Median specimen weights were comparable between groups.
    • Postoperative hemoglobin levels and estimated blood loss were similar, with no significant differences observed.
    • No bile leakage or significant postoperative bleeding occurred in either group.

    Conclusions:

    • Hepatic resection in pigs can be performed quickly and safely using a linear stapling device.
    • Stapler resection was perceived as easier and slightly quicker than conventional hepatic resection.
    • Linear stapling device offers a viable and potentially advantageous alternative for segmental liver resection in this animal model.
