Abstract
The goal of this study was to examine the safety and effectiveness of right lobectomy in living donor liver transplantation (LDLT). From January 1999 to January 2002, 100 cases of LDLT were performed at Seoul National University Hospital; 45 involved right lobectomy (RL), 17 involved extended left lobectomy (ELL), 37 involved left lateral segmentectomy (LLS), and 1 involved right posterior segmentectomy. The outcome of RL was compared with those of other types of hepatectomy. An RL resulted in a longer operative time (minutes) than an LLS (349.0 ± 65.1 versus 286.7 ± 54.0, P < .01), but not an ELL (351.2 ± 84.3, P =.99). The hospital stay (days) in the RL group (14.4 ± 3.1) was longer than for those in the ELL group (11.7 ± 1.7, P < .01) and the LLS group (11.7 ± 1.9, P < .01). The drain amount (mL) of the postoperative third day in the RL group (194.4 ± 143.4) was larger than for those in the ELL group (56.8 ± 84.1, P < .01) and the LLS group (46.5 ± 39.6, P < .01). The postoperative peak serum level of total bilirubin (mg/dL) was 3.0 ± 1.5 in the RL group, 1.9 ± 0.7 in the ELL group, and 1.9 ± 0.9 in the LLS group (P < .01, RL versus LLS, ELL). There was no mortality or major morbidity and no reoperation of donors. Right lobectomy is a relatively safe and effective procedure in LDLT, but brings more potential risks and morbidity in donors.
