Surgical Techniques and Outcomes of Pure Laparoscopic Donor Right Posterior Sectionectomy for Living Donor Liver Transplantation

Right posterior section (RPS) graft for living donor liver transplantation (LDLT) is an alternative graft in a live liver donor with insufficient remnant left lobe volume and portal vein anomaly. In recent decades, laparoscopic liver resection (LLR) has been widely adopted by hepatobiliary surgeons, and the indication for LLR have expanded to donor hepatectomy. Laparoscopic-approach donor surgery would be ideal for liver donation in healthy individuals, due to the fast return to normal life and satisfaction with the incisional scar. However, there have been no reports regarding laparoscopic donor hepatectomy for RPS graft. Herein, we report surgical outcomes and techniques of pure laparoscopic donor right posterior sectionectomy (PLDRPS) for LDLT. The institutional review boards of our center (number 2019-03-080) approved this study.
