title: [Start of an adult living donor liver transplantation program in Switzerland].
abstract: The shortage of cadaver organs has prompted transplant centres to seek new sources of grafts. While living-donor left lobe transplantation (segments II and III) is an established procedure for children, living donor right liver transplantation (segments V, VI, VII, VIII), which can provide adequate liver mass for an average-sized adult patient, is technically more demanding and potentially associated with higher risks for the donor. In view of the permanent shortage of organs in Switzerland, we started an adult living donor liver transplantation programme in 1999 with the approval of the Clinical Ethics Committee of Geneva University Hospitals. Donor evaluation was performed only after the recipient had been officially registered for transplantation in the national waiting list. Preoperative evaluation consisted of a preliminary information phase with blood tests and Doppler ultrasonography, a second phase with radiological non invasive investigations (CT scan with volume measurements, magnetic resonance cholangiography) and a third phase including liver biopsy and angiography. A formal psychiatric evaluation was performed in all cases and detailed consent was required. Eight potential donors were investigated, 5 were not retained because of too small right liver or steatosis, and 3 were accepted (wife, son, sister). Living-donor hepatectomy was performed without interrupting the vascular blood flow. The liver graft was perfused ex-situ with University of Wisconsin solution. The grafts were anastomosed to the preserved vena cava of the recipient and the portal and arterial anastomoses were performed without interposition grafts, with short cold ischaemic times in the 3 cases. The graft-to-recipient weight ratio ranged from 1.04 to 1.12%. The grafts worked immediately; the post-operative course in the 3 recipients was unremarkable and no rejection episode occurred. Significant complications were observed in one donor (percutaneously drained bilioma and spontaneously resolved popliteal sensory palsy). Living-donor right liver transplantation is a potentially valuable solution to the increasing shortage of donor organs. The procedure can be performed safely provided stringent criteria for donor selection, for donor-recipient coupling (> 1% graft to body weight ratio) and for centre selection (experience in liver surgery, reduced and split liver transplantation) are applied.
