Perpetuating proficiency in donor right hepatectomy for living donor liver transplantation.

BACKGROUND/OBJECTIVE Donor right hepatectomy (DRH) was developed by master liver surgeons and has been applied in many liver transplant centers as the mainstay for adult living donor liver transplantation. It is a major and complex surgical operation performed on living liver donors for the benefit of liver recipients. The donors deserve the lowest though inevitable morbidity and mortality. In this study, the surgical outcomes of DRH performed by newer surgeons at an established center were studied to assess the transferability of the techniques of this standardized procedure. METHODS We studied 450 consecutive DRHs performed by 11 surgeons. Three surgeons initiated and developed the transplant program and performed the first 200 DRHs (Era I). The role of chief surgeon in the following 250 DRHs (Era II) was gradually taken up by four newer surgeons with close guidance initially. RESULTS Blood loss and operation time at the end of Era I versus the beginning of Era II were 251 vs. 341 mL and 391 vs. 497 minutes. The learning curve effect in Era I did not occur in Era II. The complication rates of the last 50 cases in Era I and Era II were 16% and 24%, respectively. Era I had one donor death whereas Era II had no donor death. CONCLUSION At an established center, DRH can be carried out safely by newer surgeons with good outcomes.
