Posttraumatic intestinal stenosis presenting as a perforation: Report of a case

A 78-year-old woman was admitted to the hospital after falling into a ditch approximately 1m deep and sustaining a blunt abdominal trauma with a left femur fracture. On the tenth day after admission, symptoms of a small bowel obstruction occurred. A nasogastric tube was inserted, and the symptoms thus improved. She sometimes complained of abdominal pain during the 12 months after the fall, but recovered with conservative management. The next year, she was readmitted to the hospital for a pin extraction of the left femur bone. During this admission, 15 months since her admission after her fall, she again complained of abdominal pain. Abdominal pain increased with a muscular defense, and abdominal X-rays revealed free air. She was referred to our hospital with a diagnosis of perforative peritonitis, and emergency surgery was performed, Upon laparotomy, circumferential stenoses of the small bowel were recognized in the proximal segments about 40 cm, 80 cm, and 100 cm from the ileocecal region. In addition, a perforation and prominent dilatation of the bowel segment was observed just proximal to the stenosis about 100 cm from the ileocecal region. She underwent a small intestinal resection at two sites. There were no findings of an intestinal specific ulcer, such as Crohn's disease, intestinal tuberculosis, or malignancy, based on the results of a histopathological examination.
