OBJECTIVES: University of Wisconsin solution has twice the cold hepatic preservation time as does Euro-Collins solution. Histidine-tryptophan-ketoglutarate has a lower potassium content than does University of Wisconsin solution and is used more frequently. To date, however, studies comparing University of Wisconsin and histidine-tryptophan-ketoglutarate in live-donor liver transplantation are lacking. We therefore sought to examine the hepatic function of live-donor liver transplantation allografts preserved in University of Wisconsin solution as compared with those preserved in histidine-tryptophan- ketoglutarate solution. MATERIALS AND METHODS: Between July 2003 and August 2004, 33 live-donor liver transplantations were performed at the University of Rochester Medical Center, Rochester, NY, USA. University of Wisconsin solution was used for the first 9 allografts, and histidine-tryptophan-ketoglutarate was used for the subsequent 24 allografts. Daily total bilirubin, aspartate amino transferase, amino alanine transferase, alkaline phosphatase, gamma glutamyl transpeptidase, and international normalized ratio levels were measured for the first 8 postoperative days. Peak values were compared between the groups. RESULTS: There was no primary graft nonfunction in either group. Two patients in the histidine-tryptophan- ketoglutarate group developed hepatic artery thromboses and underwent a retransplantation. Mean peak aspartate amino transferase and amino alanine transferase levels were higher in patients in the histidine-tryptophan-ketoglutarate group (aspartate amino transferase, 661+/-801 U/L; amino alanine transferase, 696+/-964 U/L) than they were in patients in the University of Wisconsin group (aspartate amino transferase, 439+/-415 U/L; amino alanine transferase, 464+/-376 U/L); however, this difference was not significant. Mean total bilirubin, alkaline phosphatase, and gamma glutamyl transpeptidase levels, and international normalized ratios were similar in both groups. CONCLUSIONS: University of Wisconsin and histidine-tryptophan- ketoglutarate solutions are both effective in preserving live-donor liver allografts. In the current study, patients in the histidine-tryptophan-ketoglutarate group had higher peak aspartate amino transferase and amino alanine transferase levels initially, but these became almost identical by postoperative day 8.
