Abstract
In general, with large mesenteric tumors it may be rather difficult to determine whether infiltration into adjacent large vessels occurred. We wish to stress the importance of preparation for microsurgery when a huge lesion appears close to a large artery in preoperative images, based on our experience of successful microscopical reconstruction of a superior mesenteric artery (SMA) and marked improvement of blocked vascular flow to the small intestine during the surgery. We have experienced a case of mesenteric fibromatosis (MF) invading the SMA and vein, contrary to preoperative expectation. The patient underwent extirpation of a MF, 21 cm in size, with reconstruction of the SMA by microsurgery. The sacrificed small intestine was only 80 cm of the distal ileum with the benefit of microscopic anastomosis between the SMA and a major jejunal artery. Preparations for microscopic surgery must be made with resection of large lesions, because involvement of mesenteric large vessels may be expected. It is possible for microsurgery to extend indications for surgical resection of huge mesenteric tumors.
