Reconstruction of the abdominal wall by using a combination of the human acellular dermal matrix implant and an interpositional omentum flap after extensive tumor resection in patients with abdominal wall neoplasm： A preliminary result

AIM： To present our trial using a combination of the human acellular dermal matrix （HADM） implant and an interpositional omentum flap to repair giant abdominal wall defects after extensive tumor resection. METHODS： Between February and October of 2007, three patients with giant defects of the abdominal wall after extensive tumor resection underwent reconstruction with a combination of HADN and omentum flap. Postoperative morbidities and signs of herniation were monitored. RESULTS： The abdominal wall reconstruction was successful in these three patients, there was no severe morbidity and no signs of herniation in the follow-up period. CONCLUSION： The combination of HADM and omentum flap offers a new, safe and effective alternative to traditional forms in the repair of giant abdominal wall defects. Further analysis of the long-term outcome and more cases are needed to assess the reliability of this technique.
