KNOT IN MECKEL'S DIVERTICULUM CAUSING STRANGULATED ILEUS

A case of strangulated ileus caused by a knot in a Meckel's diverticulum is reported. A 75-year-old woman was admitted because of sudden diffuse abdominal pain. Her symptoms became worse despite conservative treatment, and she went into shock. Abdominal CT scan and clinical findings suggested strangulated ileus. There fore, an emergency operation was performed. At laparotomy. a large amount of bloody fluid and strangulation of the intestine caused by a knot in a Meckel's diverticulum without adhesions or bands was found. Resection of the necrotic intestine including the diverticulum was performed. Histopathological examination showed a diverticulum containing all layers of the ileum. Strangulation by a knot is a very rare complication of Meckel's diverticulum. Such a diverticulum characteristically has a long neck, an ampulla at its distal end, and is freely mobile.
