Transmesosigmoid hernia in adult is very rare. A 60-year-old man admitted for sudden onset of severe abdominal pain was found in plain X-ray and CT of the abdomen to have a small intestinal gas image and an air-fluid level, and abdominal ultrasonography shows ascites and keyboard sign. Under a diagnosis of strangulated ileus, we conducted emergency surgery. Laparotomy showed an oval defect 5 cm in diameter in the sigmoid mesocolon that strangulated the small intestine. The man was discharged on postoperative day 10 without complications.
