Preservation injury (PI) is defined as hepatic dysfunction that occurs within 10 days of liver transplantation (OLT) but spontaneously resolves. However, we noted two new patterns: one characterized by histologic evidence of preservation injury that occurs at later than 10 days post-OLT (late PI), and a second, of persistent charge in liver biopsies > 10 days post-OLT (persistent PI). To characterize these new patterns, we performed a retrospective study of patients who underwent liver biopsies for hepatic dysfunction post-OLT from September 1993 to March 1998. The outcome of the 61 patients with preservation injury on liver biopsy after OLT was followed until the last clinic visit or death. Thirty patients had early PI, 16 patients had persistent preservation injury and 15 patients, late onset preservation injury. There were no significant differences in the age (P = .28), sex (P = .77), follow-up time (P = .78), cold ischemia (P = .3), or warm ischemia time (P = .16) between these groups. There was also no significant association between early preservation injury or persistent preservation injury with the development of acute or chronic rejection (P = .19). The overall survival rates at 1, 3, and 5 years was 52%, 45%, and 45%, respectively. There was no significant difference in survival between early, persistent, and late PI patterns (P = .59), although there was a trend toward better survival for patients with early preservation injury. The survival of OLT patients with persistent or late preservation injury is poor and should prompt consideration for retransplantation.
