Surgical anatomy of donor extended right trisegmentectomy before orthotopic liver transplantation in children

Authors


Abstract

Liver transplantation is now accepted as the treatment of choice for children with end stage liver disease. A major constraint has been the shortage of donor organs of appropriate size. The use of reduced size adult organs has partially alleviated this problem but the previous technique employed was limited to a donor:recipient body-weight disparity of not greater than 3:1. Recently a new technique has been described that allows safe transplantation with a donor:recipient weight ratio of greater than 10:1. This should greatly increase the paediatric donor pool. Anatomical landmarks and techniques necessary for donor reduction hepatectomy are described from the dissection of 50 adult cadaveric livers. Variations in all important biliary and vascular structures necessitated adjustments in operative technique.
