Comparison of clinical effects between pediatric living donor liver transplantation and deceased donor liver transplantation / 天津医药

ABSTRACT

Objective To analyze and evaluate the efficacy of living donor liver transplantation (LDLT) and deceased donor liver transplantation (DDLT). Methods The clinical data of prognosis and influencing factors of 320 children with liver transplantation were analyzed retrospectively. The 320 children were divided into LDLT group (n=252) and DDLT group (n=68) based on their operation styles. In LDLT group, all donors to recipients were immediate relatives within three generation. In DDLT group, all livers were obtained from cardiac death or brain death donors. The survival and incidence of complications were observed between two groups. Results The 1-year, 2-year and 3-year cumulative survival rates for recipients were 95.1%, 93.5% and 93.5% in LDLT group, and 92.3%, 92.3% and 82.4% in LDLT group. There was no significant difference between the two groups (Log-rank χ2=0.69,P=0.41). During the follow-up period,14 cases died (5.56%) in LDLT group, in which 8 deaths due to respiratory complication, 3 deaths due to multiple organ failure, and 3 deaths due to graft failure. In DDLT donor group, 5 cases died (7.35%), in which 1 death due to respiratory complication, 2 deaths due to multiple organ failure, 1 death due to intra-abdominal hemorrhage, and 1 case of unknown cause of death. There were no significant differences in portal vein thrombosis (PVT), outflow tract obstruction, biliary tract complications and pulmonary infection between the two groups (P>0.05). The ratio of hepatic artery thrombosis (HAT) was lower in LDLT group than that of DDLT group (1.98%vs. 10.29%,χ2=10.245,P<0.01). Conclusion Living donor liver transplantation is an effective method to treat end-stage liver disease.
