Materials And Methods:
During the last 9 years we treated 14 patients with a diagnosis of intra-abdominal fibromatosis. The 11 patients who received an intestinal allograft included isolated intestine (n = 6), liver-intestine (n = 1), intestine-kidney (n = 1), multivisceral (n = 1), multivisceral-kidney (n = 1), multivisceral-no liver (n = 1). Three patients received an intestinal autograft after partial abdominal evisceration and ex vivo tumor resection. Three patients additionally underwent an abdominal wall allograft.
Results:
At follow-up until August 2004, all autotransplant patients are alive. Four intestinal transplant patients died within the first postoperative month. There were three graft losses. A patient who lost his graft early postoperatively was retransplanted but died of sepsis shortly there after. Two more patients lost their graft due to severe rejection and were retransplanted successfully. Two patients developed desmoid tumor recurrence in their abdominal or thoracic wall. Ten patients are alive 1 to 9 years posttransplantation. Nine have fully functioning grafts and one patient requires TPN supplementation at night due to dysmotility of her autograft.
Conclusion:
Intestinal allo-, or autotransplantation combined with transplantation of the abdominal wall can be lifesaving for patients suffering from extensive intra-abdominal fibromatosis.
