Summary

Liver resection using a linear stapling device significantly reduces operative time and blood loss compared to the finger-fracture technique. This study shows stapling is a feasible method for liver resection in pigs.

Area of Science:

  • Veterinary Surgery
  • Surgical Innovation

Background:

  • Liver resections are complex surgical procedures.
  • Minimizing operative time and blood loss is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy of a linear stapling device for liver resection.
  • To compare stapler-assisted resection with the conventional finger-fracture technique in pigs.

Main Methods:

  • Thirteen pigs underwent left liver lobe resection.
  • Animals were randomly assigned to either linear stapler (RLG 90R) or finger-fracture resection.
  • Postoperative outcomes including operative time and blood loss were assessed.

Main Results:

  • Stapler-assisted resection had a median operative time of 27 minutes, significantly shorter than finger-fracture (42.5 minutes; p=0.0065).

  • Median blood loss was significantly lower with the stapler (275 ml) compared to finger-fracture (425 ml; p=0.015).
  • No significant bleeding or biliary leakage was observed in the stapler group post-operatively.

    • Conclusions:

    • Linear stapling is a feasible and effective method for liver resection.
    • Stapler use in liver resection offers significant advantages in reducing operative time and blood loss.
    • This technique shows promise for improving surgical outcomes in liver procedures.
