[Treatment of meconium ileus equivalent].

A 12-year old boy with mucoviscidosis developed a mechanical obstruction of the small intestine. The diagnosis of a meconium ileus equivalent was made and a conservative treatment was started. After this treatment failed, a laparotomy was performed which verified the diagnosis of a meconium ileus equivalent. It was possible to move the inspissated feces inside the terminal ileum into the ascending colon. The postoperative course was uneventful. The etiology, differential diagnosis, and both conservative and operative treatment of this complication of the mucoviscidosis are discussed.
