Abstract:
Objective To evaluate the efficacy of liver grafts with warm ischemia and with different cold preservation time in liver transplantation.Methods The clinical data of 154 patients who received liver transplantation at the First Affiliated Hospital of Sun Yat-sen University from January 2006 to December 2007 were retrospectively analyzed.The warm ischemia time of the liver grafts obtained from the non-heart-beating donors was within 10 minutes.According to cold perservation time of the liver grafts,patients were divided into 3 groups:the cold preservation time of the liver grafts was within 8 hours,8-12 hours and above 12 hours in group I(n=58),group Ⅱ(n=62)and group Ⅲ(n=34),respectively.The peak level of alanine aminotransferase(ALT),primary graft dysfunction(PGD)after liver transplantation,acute rejection response,biliary complications,vessel complications,perioperative infections and the survival of liver grafts and recipients among the 3 groups were analyzed via chi-square test,t test and variance analysis.Results No PGD was detected in the 3 groups after liver transplantation.All patients were followed up for 8-32 months.The peak level of ALT,incidence of infection and biliary complication,survival of liver grafts and recipients were(482±357)U/L,12%(7/58),12%(7/58),86%(50/58)and 88%(51/58)in group Ⅰ,and were(1274±608)U/L,29%(10/34),26%(9/34),68%(23/34)and 71%(24/34)in group Ⅲ,with significant difference between the 2 groups(t=5.23,X~2=4.28,6.77,4.51,4.28,P<0.05).The peak level of ALT in group Ⅱ was(953±424)U/L,which was significant higher than(482±357)U/L in group Ⅰ(t=4.76,P＜0.05).Conclusions Liver grafts with a warm ischemia time shorter than 10 minutes could tolerate the injury caused by cold preservation with the maximum time of 12 hours.The incidences of biliary complications and postoperative infections are significantly increased and the survivals of liver grafts and recipients are decreased when the cold preservation time exceeds 12 hours.
