[A Case of Ileus Due to Colon Cancer with Non-Occlusive Mesenteric Ischemia].

: Abdominal computed tomography(CT)revealed ileus due to sigmoid colon cancer in a 68-year-old man with abdominal pain, and endoscopic decompression using a transanal ileus tube was attempted. The blood test on the following day showed a marked increase in CRP 46.13mg/dL. Abdominal contrast CT was performed, and mesenteric ischemia was confirmed. Emergency surgery was performed on the same day. The ileum, and ascending, transverse, and descending colon appeared mottled and necrotic and were excised. A specialized diet started on the 5th postoperative day, and parenteral nutrition was used for a long period of time, due to the possibility of short bowel syndrome. The ileostomy and colostomy was closed 57 days after the operation. The patient finished parenteral nutrition on the 88th postoperative day without obvious nutritional absorption disorder and was discharged on the 94th postoperative day as oral intake only. We reported a case of ileus due to colon cancer with non-occlusive mesenteric ischemia(NOMI).
