Abstract

Five hundred ninety-three cadaveric livers were used for primary liver transplantation between October 24, 1987, and May 19, 1989. The grafts were procured with a combined method, using in situ cooling with cold electrolyte solution and backtable flushing with UW solution. The mean cold-ischemia time was 12.8 (range 2.4-34.7) hr. The cases were divided into 5 groups according to the cold-ischemia time: group 1: less than 10 hr (n = 223); group 2: 10-14 hr (n = 188); group 3: 15-19 hr (n = 101); group 4: 20-24 hr (n = 52); and group 5: greater than or equal to 25 hr (n = 29). There was no difference between the 5 groups in 1-year patient survival, highest SGOT in first week after operation, and SGOT and total bilirubin during the first month after operation. However, with a logistic regression model, the retransplantation rate (P = 0.001) and primary nonfunction rate (P = 0.006) significantly rose as cold-ischemia time increased, meaning that the equivalency of patient survival was increasingly dependent on aggressive retransplantation.
