Summary
Laparoscopic liver procurement is feasible for live donor liver transplantation. This minimally invasive technique successfully preserved vital vascular and biliary structures, offering a potential advancement in organ donation.
Area of Science:
- Minimally invasive surgery
- Transplant surgery
- Surgical innovation
Background:
- Laparoscopic donor nephrectomy has advanced renal transplantation.
- The potential for laparoscopic techniques in liver transplantation remains largely unexplored.
- Live donor liver transplantation requires innovative procurement methods.
Purpose of the Study:
- To investigate the feasibility of laparoscopic hepatic lobe procurement for live donor liver transplantation.
- To describe a novel surgical technique for laparoscopic liver procurement.
- To assess the technical and physiological viability of this approach.
Main Methods:
- Developed and refined a laparoscopic liver procurement technique in porcine models (n=12) and human cadavers (n=2).
- Utilized CO2 pneumoperitoneum, liver mobilization, and ultrasonic aspiration for parenchyma transection.
- Preserved hepatic artery, portal vein, and hepatic veins without temporary vascular occlusion.
Main Results:
- Successfully performed laparoscopic hepatic lobectomies in the study models.
- Maintained integrity of vascular and biliary structures essential for transplantation.
- Achieved procurement times under 4 hours from pneumoperitoneum establishment.
Conclusions:
- Laparoscopic liver procurement is technically feasible for live donor liver transplantation.
- The described technique preserves critical structures necessary for successful organ transplantation.
- This approach presents a viable option from both technical and physiological standpoints.
