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 airfluid 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.
