A comparative study of postoperative outcomes between minimally invasive living donor hepatectomy and open living donor hepatectomy: The Korean organ transplantation registry

Abstract

Background: This study evaluated the safety and effectiveness of minimally invasive living donor hepatectomy in comparison with the open procedure, using Korean Organ Transplantation Registry data. Methods: We reviewed the prospectively collected data of all 1,694 living liver donors (1,071 men, 623 women) who underwent donor hepatectomy between April 2014 and December 2017. The donors were grouped on the basis of procedure type to the minimally invasive procedure group (n = 304) or to the open procedure group (n = 1,390) and analyzed the relationships between clinical data and complications. Results: No donors died after the procedure. The overall complication rates after operation in the minimally invasive procedure group and the open procedure group were 6.2% and 3.5%, respectively. Biliary complications were the most frequent events in both groups (minimally invasive procedure group, 2.4%; open procedure group, 1.6%). The majority of complications occurred within 7 days after surgery in both groups. The duration of hospitalization was shorter in the minimally invasive procedure group than in the open procedure group (9.04 ± 3.78 days versus 10.29 ± 4.01 days; P < .05). Conclusion: Based on its similar outcomes in our study, minimally invasive donor hepatectomy cannot be an alternative option compared with the open procedure method. To overcome this, we need to ensure better surgical safety, such as lower complication rate and shorter duration of hospitalization. © 2021 The Author(s)
