OBJECTIVETo evaluate the surgical procedures and therapeutic effect of organ cluster transplantation in treating abdominal multiple organ malignant tumors.

METHODSTwo patients with abdominal multiple organ malignant tumors received organ cluster transplantation in May and August 2004. The excised specimen included liver, pancreas, duodenum, stomach, spleen, mesenteric and epigastric lymph nodes. The transplanted organs included liver, pancreas, duodenum. Superior mesenteric artery was involved in the malignancy in one case and was transected and anastomosed to right common iliac artery.

RESULTSThe patients waked up 4 and 5 hours post operation and began recovering 3 and 5 days after. Dynamic examinations showed that the functions of grafted liver, pancreas and duodenum obtained normal function in 10 days post the transplantation. One patient survived for 12 months postoperatively and died of recurrence of cancer; The other recovered uneventfully after transplantation, and discharged automatically 20 days after.

CONCLUSIONSAbdominal organ cluster transplantation is technically feasible and effective for patients with abdominal multiple organ malignant tumors.
