ObjectiveEvaluate outcome of left-lobe graft (LLG) first combined with purely laparoscopic donor hemihepatectomy (PLDH) as a strategy to minimize donor risk.BackgroundAn LLG first approach and a PLDH are 2 methods used to reduce surgical stress for donors in adult living donor liver transplantation (LDLT). But the risk associated with application LLG first combined with PLDH is not known.MethodsFrom 2012 to 2023, 186 adult LDLTs were performed with hemiliver grafts, procured by open surgery in 95 and PLDH in 91 cases. LLGs were considered first when graft-to-recipient weight ratio ≥0.6%. Following a 4-month adoption process, all donor hepatectomies, since December 2019, were performed laparoscopically.ResultsThere was one intraoperative conversion to open (1%). Mean operative times were similar in laparoscopic and open cases (366 vs 371 minutes). PLDH provided shorter hospital stays, lower blood loss, and lower peak aspartate aminotransferase. Peak bilirubin was lower in LLG donors compared with right-lobe graft donors (1.4 vs 2.4 mg/dL, P < 0.01), and PLDH further improved the bilirubin levels in LLG donors (1.2 vs 1.6 mg/dL, P < 0.01). PLDH also afforded a low rate of early complications (Clavien-Dindo grade ≥ II, 8% vs 22%, P = 0.007) and late complications, including incisional hernia (0% vs 13.7%, P < 0.001), compared with open cases. LLG was more likely to have a single duct than a right-lobe graft (89% vs 60%, P < 0.01). Importantly, with the aggressive use of LLG in 47% of adult LDLT, favorable graft survival was achieved without any differences between the type of graft and surgical approach.ConclusionsThe LLG first with PLDH approach minimizes surgical stress for donors in adult LDLT without compromising recipient outcomes. This strategy can lighten the burden for living donors, which could help expand the donor pool.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
