We retrospectively reviewed the medical records of 186 living liver donors from August 2008 to September 2010. Donors were divided into two groups according to group IIO (n = 81) versus Controls (no IIO, n = 105). Within each group, donors were subdivided to evaluate Peak values of LFTs and complications into according the degree of MaS: group I_5 (n = 36); IIO + <5%MaS, group I_30 (n = 45); IIO + 5%-30%MaS, group C_5 (n = 55); Control + <5%MaS, and group C_30 (n = 50); Control + 5%-30%MaS.
Peak aspartate aminotransferase (AST) and alanine aminotransferase (ALT) among IIO were significantly higher than Non-IIO. These values in groups I_5 and I_30 were significantly higher than groups C_5 and C_30, respectively (all, P < .01). The overall postoperative complications were comparable between groups IIO and Non-IIO, but significantly higher among group I_30 than groups I_5 (P = 0.024) and C_30 (P = .012).
Application of IIO in donors with mild macrosteatosis undergoing right hepatectomy showed significantly higher postoperative peak liver functions tests and number of overall complications than those without IIO.
