Liver grafts can be preserved overnight.
The introduction of University of Wisconsin solution has made liver transplantation a semi-elective procedure. However, many studies have suggested that cold storage must not exceed 12 hours to avoid ischemic-type biliary complications, to reduce the incidence of primary nonfunction and to improve graft and patient survival. The aim of this study was to compare the function of livers transplanted as soon as possible after the liver was harvested and those preserved overnight. Over a 42-month period, we studied 133 elective orthotopic liver transplantation procedures. When cold ischemia started after 6 PM, patients underwent transplantation the following morning (group A), whereas the remainder underwent transplantation immediately (group B). Cold ischemia lasted 13.7 hours and 9.5 hours in groups A and B, respectively (P < .001). The two groups were comparable in terms of initial and late biochemical liver function, the rates of primary nonfunction (6.5% in group A, 6.8% in group B), acute rejection (45.6% in group A, 45.7% in group B), and vascular and infectious complications. No ischemic-type biliary complications were observed. Graft and patient survival were similar in both groups (72.4% v 75.4% and 72.9% v 75.8% in groups A and B, respectively). These results suggest that having taken a cut off at 6 PM to divide the groups into those that underwent transplantation consecutively and those deferred to the morning, the difference between the two groups in terms of storage is relatively modest. Elective liver transplantation can be performed after overnight graft storage without increasing short-term or long-term morbidity or mortality rates.
