Incidence and management of abdominal closure-related complications in adult intestinal transplantation

[摘要]：Background. We sought to determine the best strategy to overcome difficult abdominal wall closures in intestinal transplantation (ITx).Methods. Among 38 adult recipients of 39 ITxs from deceased donors, the median number of previous laparotomies was 2.0 per patient, with a median donor-to-recipient body weight ratio of 1.1. Eight patients (21%) had full residual intestinal length before transplant. Abdominal wall closure after transplant was considered difficult in 15 (39.5%) patients (group A). To overcome size mismatching, we performed two graft reductions, five skin-only closures, one two-step abdominal wall closure, four prosthetic mesh closures, and three abdominal wall transplants. In the remaining 23 (60.5%) patients, a regular abdominal closure was performed (group 13).Results. Twelve patients (32%) experienced complications related to abdominal wall closure, 10 (67%) in group A and 2 (8.7%) in group B (P<0.0001). Abdominal closure-related mortality was 6.7% (1/15) and 4.3% (1/23), respectively (P = 1.0). In group A, there were six incisional hernias (one of them after abdominal wall transplant), although all four patients with mesh experienced mesh infection. Two of them developed intestinal fistulae, leading to patient death in one case. In group 13, one patient with unfavorable donor/recipient size matching had fatal vascular thrombosis of a multivisceral graft caused by compression after abdominal closure.Conclusions. A careful evaluation of abdominal cavity is necessary in candidates for ITx. In our experience, closure with mesh should be avoided because of the high rate of complications. Abdominal wall transplantation is a feasible option when a difficult abdominal wall closure is expected.
