To overcome the barrier of size match, right lobe graft has been widely used in living donor liver transplantation (LDLT). We assessed donor outcome, with a focus on remnant liver volume (RLV) after right hepatectomy based on the experiences of 2 LDLT centers, as a means of guiding the establishment of safe RLV limits for donor right hepatectomy. Between January 2002 and December 2003, a consecutive 146 liver donors who underwent right hepatectomy with at least 12 months of follow‐up were enrolled in this study. Donors were grouped into 2 groups according to RLV: group 1 (n = 74), <35% (range, 26.9‐34.9) and group 2 (n = 72), ≥35% (35.0‐46.8). No donors died or suffered a life‐threatening complication. Mean peak serum postoperative aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (IU/L) levels were 219.5 ± 79.9 and 231.5 ± 83.3 in group 1 and 210.3 ± 81.6 and 225.8 ± 93.0 in group 2 ( P = 0.497 and 0.699), respectively. Mean peak serum total bilirubin (TB) (mg/dL) level in group 1 (3.4 ± 1.6) was higher than in group 2 (2.8 ± 1.4; P = 0.023). Overall 23 (15.8%) major morbidities, 10 in group 1 (13.5%) and 13 in group 2 (18.1%), occurred according to Clavien's system ( P = 0.939). These included bleeding (n = 3 in group 1 and n = 6 in group 2; P = 0.282), ileus (n = 3 and 1; P = 0.324), biliary leakage (n = 4 and 4; P = 0.968), and pneumonia (n = 0 and 2; P = 0.149). Minor morbidities were also comparable in the 2 groups. In conclusion, the outcome of donors with an RLV of <35% was not different from that of donors with an RLV of ≥35%, with the exception of transient cholestasis. Therefore, a remnant RLV of <35% does not appear to be a contraindication for right liver procurement in living donors. Liver Transpl 12:201–206, 2006. © 2006 AASLD.
