A 31-year-old woman was admitted to the hospital because of severe abdominal pain. Her abdomen had severe tenderness, rebound tenderness, and muscle defense which presented with peritonitis. A chest X-ray showed free air under her diaphragm. She had emergency surgery. A perforation about 9mm in diameter was observed in the ileum 40cm proximal from the Bauchin valve. We found two longitudinal ulcers in the resected ileum within a perforation and checked the other small intestine with intraoperative endoscopy through a corrugated tube. We were able to find other two ulcers in the remnant ileum and remove the ileum with ulcers as shortly as possible.
