Background
Although several publications have reported donor morbidities, deterioration of liver function, which may cause posthepatectomy liver failure (PHLF), was not assessed specifically.
Methods
The incidence of PHLF proposed by the International Study Group of Liver Surgery (ISGLS-PHLF) was analyzed among 257 living donors. ISGLS-PHLF was defined by an increased international normalized ratio and hyperbilirubinemia on or after postoperative day 5.
Results
ISGLS-PHLF was identified in 21 donors (8 %), of which 18 (85.7 %) were grade A, 2 (9.5 %) were grade B, and 1 (4.8 %) was grade C. The average hospital stay without ISGLS-PHLF was 15 ± 1 days, which extended along with increasing grades (p = 0.03). In univariate analysis, right hepatectomy was significantly associated with the incidence of ISGLS-PHLF (p = 0.02), and right hepatectomy (p = 0.002) and operation time (p = 0.01) in multivariate analysis. Of 176 right lobe donors, 19 (10.8 %) developed ISGLS-PHLF, of which 16 (84.2 %) were grade A, 2 (10.5 %) were grade B, and 1 (5.3 %) was grade C. Operation time was significantly associated with the incidence of ISGLS-PHLF in univariate (p = 0.002) and multivariate (p = 0.003) analyses.
Conclusions
Right lobe donation surgery is associated with a higher incidence of ISGLS-PHLF.
