METHODS The swine segmental small bowel graft was autotransplanted after it was preserved with lactated Ringer′s (LR), Euro Collins (EC), hyperosmolarity citrate adenine (HC A) and WMO 1 solutions for 10, 18 and 24 hours, respectively. The recipient survival rate, morphological structure, graft mucosal energy substances and Na + K + ATPase activity were studied, and graft absorption was estimated with D xylose absorption test. RESULTS The morphological study of the grafts preserved with LR or HC A solution for 10 hours or with EC and WMO 1 solution for 18 hours was normal 6 days after operation. Mucosal ATP, total adenine nucleotides (TAN) contents and Na + K + ATPase activity of the graft preserved with EC or WMO solution were higher than that of the graft preserved with LR or HC A solution. Serum level of D xylose was higher in EC and WMO 1 groups than in LR and HC A groups when the graft was preserved for 24 hours. CONCLUSIONS EC and WMO 1 solutions can preserve the swine small bowel up to 18 hours, which are superior to LR and HC A solutions.展开更多
