    Abstract:
    BACKGROUND: A safe and effective preservation solution is a precondition for successful orthotopic liver transplantation (OLT). This study compared University of Wisconsin (UW) and histidine-tryptophan-ketoglutarate (HTK) solutions in OLT. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 137 primary cadaveric. OLT performed between January 2003 and December 2006 at our institution. Sixty-eight grafts were harvested using UW and 69 using HTK. Recipients were managed similarly in regard to operative techniques and immunosuppression. We collected donor data including serum transaminases, serum sodium, ICU stay and assessed macroscopic liver quality. Recipient serum transaminases were collected on postoperative days 1, 7, 14, and 30. We compared biliary and vascular complications, as well as patient and graft survivals. RESULTS: Mean serum bilirubin levels were slightly higher in the HTK group at 1,7,14, and 30 days after transplantation, whereas transaminases were higher in the UW group. Primary nonfunction occurred in 1 patient in each group. Retransplantation was performed in 5 patients in the UW and in 9 patients in the HTK group. Biliary complication rates were similar in the UW and HTK groups (22% and 17%, respectively). Six arterial complications occurred in the HTK (8.7%) and 2 in the UW group (2.9%; P < .05). Mean follow-up was 25 months. Graft survival at 1, 12, and 36 months was 90%, 78%, and 75% versus 90%, 71%, and 71% in the UW versus HTK groups, respectively. One-, 12-, and 36-month patient survival rates were 93%, 78%, and 75% versus 93%, 78%, and 78% in the UW versus HTK groups, respectively. CONCLUSIONS: There were no significant differences in graft and patient survivals between the 2 groups. Whereas the biliary complication rates were comparable in both groups, the arterial complications were clearly higher in the UW group (8.7% vs 2.9%; P < .05%). UW and HTK solutions seemed to be equally safe and effective in the preservation of liver grafts. The high incidence of arterial complications in the UW group requires further prospective studies.
