Abstract:
Objective To explore a simple and effective way of establishing a 30 % small-forsize liver transplantation in rats. Methods SD rats were selected as the donors and recipients. Smallfor-size orthotopic live transplantation was performed using Kamada's two-cuff method. Donor's liver was flushed via abdominal aorta and hepatectomy in situ was done. Animals were divided into 3 groups (40 pairs of rats in each): group Ⅰ , median lobe was used as graft; group Ⅱ, right of median lobe and right lobe were used as graft; group Ⅲ, median and right lobes were used as graft. The body weight of the donor was the same as the recipient in groups Ⅰ and Ⅱ , but 100～ 120 g less than in group Ⅲ. The operating time, 7-day survival and technical complications were compared among these 3 groups. Results The operating time of hepatectomy was shorter in group Ⅲ than in groups Ⅰ and Ⅱ (8. 8±0.7 vs 11.5± 1.1 vs 10.1 ±1.0 min, P＜0.01). The cold ischemia time of graft, the anhepatic time, the operating time of recipient and the transplanting successful rate showed no significant difference among the 3 groups. Compared with groups Ⅰ and Ⅱ , the incidence of bleeding,bile leakage and IVC stricture was significantly decreased in group Ⅲ (P＜0. 05). Other complications after operation showed no significant difference among the 3 groups (P＞0. 05). Group Ⅲ had more 7-days survivors and longer median survival time, but there was no significant difference among the 3groups. Conclusion Small for donor body weight with median and right lobes as graft was a more effective and simple way of establishing a 30 % small-for-size liver transplantation in rats with shorter hepatectomy time and less complications after operation.
