Analyses of the risk and operative stress for donors in living-related partial liver transplantation.
Operative risk and stress were analyzed in 28 parent-donors whose children received partial liver transplantations at the Second Department of Surgery, Kyoto University Hospital between June 1990 and December 1991. Graft-harvesting operations were classified into three types: left lobectomy (group L, n = 12), left lateral segmentectomy (group S, n = 15), and right lobectomy (n = 1). Since donor safety is a primary concern, great care was taken to minimize potential damage to the remaining lobes of the donor liver as well as the graft liver by avoiding stressful maneuvers such as hepatic vascular clamping during the transection of the hepatic parenchyma. In all cases the arterial ketone body ratio, which reflects the hepatic mitochondrial redox potential, was maintained at over 0.7 throughout the donor operation as well as postoperatively. There was no significant difference in the postoperative RBC, WBC, serum GOT, and total bilirubin between groups L and S, although the abnormalities exhibited by the single right lobectomy case tended to be larger and more prolonged. All cases were within the range acceptable for immediate discharge, and all donors of groups L and S were subsequently discharged within 14 days without any postoperative complications. The single right lobectomy donor was discharged on POD17 because of transient slight icterus, which is the only postoperative complication encountered in this series thus far. The present analyses would indicate that the risk and operative stress to the donor in living-related partial liver transplantation can be minimal when the left lobe or left lateral segment of the liver is used for the graft.
