Intestinal obstruction due to a defect in the omentum.

An unusual cause of instestinal obstruction is described in a 46-year-old woman thought before operation to have Crohn's disease. The right colon and terminal ileum had passed through a defect that had developed spontaneously in the greater omentum and had remained in that position for at least 1 year. The bowel was reduced and the multiple defects in the omentum were repaired.
