Early Experience of Pure Robotic Right Hepatectomy for Liver Donors in a Small-Volume Center.

Background and objectives: Living donor right hepatectomy has become the most common method of liver transplantation. With minimally invasive surgery, laparoscopic donor hepatectomy became possible, but with some limitations. Advancements in robotic technology made it possible to overcome these shortcomings and maximize the advantages of minimally invasive surgery in transplantation. For this reason, some centers have started robotic donor hepatectomy. Our study aimed to introduce our early experience of robotic donor right hepatectomy and investigate the feasibility of this surgery.

Methods: This study included 10 (30%) living donors who underwent pure robotic donor right hepatectomy at Dong-A University Hospital from January 1, 2020 to December 31, 2021. The medical records were analyzed to determine the short-term outcomes of these patients.

Results: The total operation time and warm ischemic time were 396.6 min ± 62.7 min and 19.7 min± 5.6 min, respectively. Moreover, there was no transfusion during the operation and no other port use and open conversion. The average real graft volume was 590 mL ± 73.5 mL, and the mean hospital stay was 8.7 d ± 2.6 d. There have been no specific complications noted in the donor group.

Conclusions: Based on our positive experience with pure robotic right hepatectomy for a liver donor, the robotic technique may be a new option for achieving minimally invasive surgery for a liver donor.
