This study demonstrates that using a vascular endostapler for liver resection significantly reduces vessel closure time and expedites the procedure. This technique proved safe and effective in 31 major hepatic resections, with minimal complications.

Area of Science:

  • Surgical Oncology
  • Gastroenterology
  • Medical Devices

Background:

  • Liver resection is a complex surgical procedure.
  • Traditional ligation techniques for vascular structures carry risks such as slipped ligatures.
  • Minimally invasive techniques are continually being explored to improve patient outcomes.

Purpose of the Study:

  • To describe and evaluate the technique of liver resection using an endovascular stapling device.
  • To assess the safety and efficacy of vascular endostaplers in major hepatic resections.

Main Methods:

  • A retrospective review of 31 patients undergoing major hepatic resections utilizing stapling techniques.
  • Application of a vascular endostapler device for portal vein and hepatic vein structures.
  • Detailed description and illustration of specific hepatectomy techniques.

Main Results:

  • No patient deaths occurred in the study cohort.
  • A single minor complication (biliary fistula) was noted, attributed to parenchymal transection, not stapler use.
  • No complications were directly linked to stapler ligations of the portal pedicle or hepatic veins.

Conclusions:

  • Endovascular stapling techniques are a safe and effective adjunct for major hepatic resections.
  • The vascular endostapler significantly reduces operative time by decreasing portal vein and hepatic vein closure duration.
  • This method minimizes risks associated with traditional ligation, potentially improving surgical safety and efficiency.
