Liver transplantation is a potential treatment for end-stage liver disease. Because of an organ shortage, living donor liver transplantation (LDLT) has recently taken the place of deceased donor livers. To reduce morbidity and improve cosmetic outcome, various minimally invasive donor surgeries, including pure laparoscopic donor hepatectomy, have been attempted. Laparoscopic liver resections lead to less blood loss, less wound-related morbidity, decreased postoperative morbidity, and shorter length of stay.^1,2 Improved laparoscopic techniques, better visualization of the operative field, and use of specialized laparoscopic instruments for transecting the liver parenchyma have allowed laparoscopic liver resection to be performed more widely. In 2002, the first case of laparoscopic donor hepatectomy was reported.³ Full laparoscopic donor right hepatectomy (LDRH) for adult LDLT was reported afterwards.^4,5 However, owing to technical difficulties, it can only be recommended to be performed by highly experienced surgeons and transplantation teams.

This study compared the outcomes of conventional open donor hepatectomy (CDRH) and LDRH based on retrospective analysis of a single-center experience. Previous studies reported that LDRH reduced morbidity, minimized tissue trauma, and improved postoperative pain and cosmetic outcome.⁶ Adequate liver mobilization, minimized hepatic injury and improved visualization by advanced laparoscopic techniques lead to the rapid recovery of patients and shorter hospital stay compared to open surgery. In this study, LDRH showed reduced blood loss and few complications. Donor safety is the most important problem in LDLT, and it is emphasized that the long operating time and increased risk of bile duct injury are important factors that need to be overcome in the future for donor safety. It should also be noted that this study is limited in that it was retrospective with a small number of patients and therefore subject to selection bias. However, the authors presented valuable data with a specific focus on LDRH for LDLT. It is expected that a collection of small retrospective studies such as this study will provide good evidence of the benefits of LDRH. LDRH is an appropriate minimally invasive procedure for living donor hepatectomy that is expected to be expanded further in the future.
