Abstract
We report a case of ileocolic fistula with delayed colon stenosis one year after abdominal blunt trauma. A 71-year-old man treated conservatively for mesenteric injury in a traffic accident was hospitalized one year later for abdominal fullness and vomiting that did not improve in conservative treatment. Colonoscopy and enterography showed a fistula between the sigomoid colon and ileum, necessitating sigomoidectomy with associated ileal resection and sigmoidostomy. Bowel and mesenteric injury are common in abdominal trauma, but delayed posttraumatic colon stenosis is especially rare, with ileocolic fistula such as in this case never, to our knowledge, reported in Japan. Delayed stenosis should be considered in those reporting ileal symptoms following abdominal trauma. Enterography is very useful in diagnosing bowel stenosis and fistula formation.
