Abdominal Wall Transplantation with Microsurgical Technique

Abstract

Many patients undergoing intestinal or multivisceral transplantation have a past history of complete midgut removal with the loss of the domain of the abdominal compartment or have severely damaged abdominal walls from repeated laparotomies, tumours or enterocutaneous fistulae. These patients may encounter severe abdominal wall closure problems at the end of transplantation, resulting in increased morbidity and mortality. It is, therefore, of paramount importance to properly cover transplanted organs in order to reduce postoperative complications. Abdominal wall transplantation was recently proposed for closure of patients undergoing both small-bowel and multivisceral transplantation: the results are encouraging. However, the technical procedure proposed requires the procurement of long segments of iliac vessels as far as the vena cava and the aorta. Since donor multiorgan procurement involves many surgical teams, the removal of these vessels, with the abdominal graft, led to their unavailability for vascular surgeons. Here we present three consecutive cases of abdominal wall transplantation in which, by taking advantage of microsurgical experience, we were able to carry out a transplantation of the abdominal wall by direct anastomosis of the epigastric vessels, obtaining a very good outcome.
