Successful treatment of a case of advanced sigmoid colon cancer with occlusion of the common celiacomesenteric trunk

Abstract

A 74-year-old man was admitted to our hospital with abdominal pain and bloody stool. The patients' history showed that he had had occlusion of the proximal common trunk of the celiac artery (CA) and the superior mesenteric artery (SMA). The inferior mesenteric artery (IMA), and the marginal artery of the colon had developed well. It was assumed that almost the entire visceral blood might be supplied by the IMA to the CA and the SMA. Our investigation revealed that the patient had advanced cancer of the sigmoid colon, which had caused intestinal obstruction. Sigmoidectomy was performed with care to avoid injuring the IMA and the marginal arcade artery. Normal hemodynamics were successfully established followed by sigmoidectomy, and cure was obtained in this patient.
