Minimizing Incision in Living Donor Liver Transplantation: Initial Experience and Comparative Analysis of Upper Midline Incision in 115 Recipients.

Living donor liver transplantation (LDLT) needs "Mercedes Benz" or "J-shaped" incision, causing short and long-term complications. An upper midline incision (UMI) is less invasive alternative but technically challenging. Reporting UMI for recipients in LDLT vs. conventional J-shaped incision. Retrospective analysis, July 2021 to December 2022. Peri-operative details and post-transplant outcomes of 115 consecutive adult LDLT recipients transplanted with UMI compared with 140 recipients with J-shaped incision. Cohorts had similar preoperative and intraoperative variables. The UMI group had significant shorter time to ambulation (3 ± 1.6 vs. 3.6 ± 1.3 days, = 0.001), ICU stay (3.8 ± 1.3 vs. 4.4 ± 1.5 days, = 0.001), but a similar hospital stay (15.6±7.6 vs. 16.1±10.9 days, = 0.677), lower incidence of pleural effusion (11.3% vs. 27.1% = 0.002), and post-operative ileus (1.7% vs. 9.3% = 0.011). The rates of graft dysfunction (4.3% vs. 8.5% = 0.412), biliary complications (6.1% vs. 12.1% = 0.099), 90-day mortality (7.8% vs. 12.1% = 0.598) were similar. UMI-LDLT afforded benefits such as reduced pleuropulmonary complications, better early post-operative recovery and reduction in scar-related complaints in the medium-term. This is a safe, non-inferior and reproducible technique for LDLT.
