title: Abdominal wall transplantation: surgical and immunologic aspects.
abstract: Abdominal wall transplantation is a type of composite tissue allograft that can be utilized to reconstitute the abdominal domain of patients undergoing intestinal transplantation. We have presented herein combined experience and long-term follow-up results of a series of abdominal wall transplants performed at 2 institutions. A total of 15 abdominal wall transplants from cadaveric donors were performed in 14 patients at the end of intestinal transplant surgery or, in 2 cases, a few days after the primary intestinal transplant. The vascular supply was through the inferior epigastric vessels, from the iliac vessels in 12 cases and via a microsurgical technique in 3 cases. Immunosuppression consisted of induction with alemtuzumab and maintenance treatment with tacrolimus monotherapy. Two grafts lost to vascular thrombosis were removed. Five patients are still alive, although all deaths were unrelated to the abdominal wall transplant. There were 3 episodes of abdominal wall graft rejection, treated with steroids; the abdominal wall graft and the intestinal grafts experienced rejection independent from each other. In summary, abdominal wall transplantation is a feasible technique for recipients of intestinal or multivisceral transplants, when the closure of the abdominal cavity by primary intention is technically impossible.
