Compared with other rat transplant models, small bowel transplantation (SBT) is associated with higher peritransplant morbidity and mortality. We describe a two-stage technique of SBT in the rat that minimizes perioperative complications and also allows immediate restoration of intestinal continuity. Inbred Lewis strain rats were used as donors and recipients. A one-stage technique was originally adopted whereby the distal 50% of the jejunoileum was transplanted followed by near-total resection of the native small intestine and restoration of intestinal continuity. Among 20 rats transplanted with this technique, only one survived longer than 30 days. With the two-stage technique, transplantation of the donor jejunoileum in continuity was performed, followed by native enterectomy 7 days later. With the two-stage technique 17 of 20 rats survived indefinitely (greater than 50 days). Other important technical modifications are described. In the hands of a skilled microvascular surgeon, the two-stage SBT technique results in consistently improved survival and minimal morbidity.
