The influence of cold ischemia time on biliary complications following liver transplantation.
Biliary complications are a continuing source of morbidity and mortality following orthotopic liver transplantation. The results of 100 whole-liver allografts performed in 92 adult patients were reviewed to determine whether cold ischemia time and preservation injury influenced both the incidence and type of biliary complications. Mean cold ischemia time was 10.2 +/- 0.5 h (range 3.6-19). Eighteen patients (19.6%) developed 25 biliary complications: there were eight anastomotic leaks, eight anastomotic strictures, six non-anastomotic strictures, two cystic duct mucoceles, and one biliary fistula following T-tube removal. Despite the high rate of reoperative surgery (68%), no death was attributable to biliary complications. Neither cold ischemia time nor early graft function influenced the rate of biliary complications or strictures of either type. Furthermore, an analysis of different factors revealed no predisposing effect of the pre-operative status of the recipient, type of biliary reconstruction, blood requirement, vascular complications, rejection or cytomegalovirus infection on the incidence of biliary complications or strictures. Only chronic rejection could be singled out as a risk factor for non-anastomotic strictures (p = 0.05). These results suggest that prolonged cold ischemia time does not seem to affect the rate or type of biliary complications following orthotopic liver transplantation. In view of these data, there is no clear reason to reconsider prolonged cold ischemia up to 15 h in University of Wisconsin solution, as it has transformed liver transplantation from an emergency operation to a semi-elective procedure and allows longer back-table preparation for graft reduction of splitting.
