INTRODUCTION: A split liver for two adults is a good theoretical option but the number of cases is low. We have tried to assess the feasibility of this technique.
MATERIALS AND METHODS: From April 2002 to April 2004, we evaluated 81 donors of which only 59 (72.8%) were used for transplantation of which 10 were grafted in other centers (pediatric or emergency code). Among the 49 donors the criteria for splitting were: ages >14 and <50 years, weight >70 and <100 kg, less than 3 days in the intensive care unit (ICU), hemodynamic stability, Na(+) < 160 mg/L, liver enzymes elevated no more than twofold, no macroscopic steatosis, and procurement in our hospital.
RESULTS: The mean donor age was 50.7 years (range: 16 to 77) of whom 25 were men (51%). The mean weight was 65.7 kg (range: 50 to 100) and days of ICU stay, 3 (range: 1 to 23). Six grafts (12%) were split. The reasons for not splitting were: age (n = 26 [53%]), weight (n = 17 [34.7%]), UCI >3 days (n = 9 [18.3%]), Na(+) > 160 (n = 1 [2%]), blood liver test elevated (n = 5 [10.2%]), steatosis (n = 6 [12.2%]), and procurement outside our center (n = 20 [40.8%]). The donors not suitable for splitting had: only one criteria (n = 12 [24.4%]; 2 (n = 23 [46.9%], 3 (n = 6 [12.2%]) or 4 (n = 2 [4.1%]). If we had had two suitable recipients, we could performed six more liver transplantations (12.2% increase).
CONCLUSIONS: The theoretical feasibility of a split liver for two adults is 12.2%, but the actual probability is lower because of lack of two adequate candidates.
