Operative outcomes of adult-to-adult right lobe live donor liver transplantation: a comparative study with cadaveric whole-graft liver transplantation in a single center.
OBJECTIVE
To evaluate and compare the operative and survival outcomes of patients who underwent right lobe live donor liver transplantation (RLDLT) and cadaveric whole-graft liver transplant (CWLT) recipients in a single institution.


BACKGROUND
Current data suggest that RLDLT has an inferior graft survival outcome when compared with CWLT.


METHODS
A prospective study was performed on 180 consecutive adult patients who underwent primary liver transplantation from January 2000 to February 2004. The operative and survival outcomes of RLDLT (n = 124) were compared with those of CWLT (n = 56).


RESULTS
Fifty-five (44%) and 16 (29%) patients were on high-urgency list in the RLDLT group and the CWLT group, respectively (P = 0.045). The preoperative Model for End-Stage Liver Disease scores were comparable in both groups. The waiting time for liver transplantation was significantly shorter in the RLDLT group. The graft weight to estimated standard liver weight ratio was significantly lower in the RLDLT group. The postoperative hospital stay and hospital mortality were comparable in the RLDLT group (1.6%) and the CWLT group (5.4%). Thirty-one (25%) patients in the RLDLT group and 3 (5%) patients in the CWLT group developed biliary stricture on follow-up (P = 0.002). At a median follow-up of 27 months, the actuarial graft and patient survival rates were 88% and 90%, respectively, in the RLDLT group, and both were 84% in the CWLT group.


CONCLUSIONS
RLDLT results in favorable operative outcomes comparable with those of CWLT. However, there is a significantly higher incidence of biliary stricture associated with RLDLT.
