[Free cecum perforation with peritonitis as a rare complication of Crohn disease].

Perforation and peritonitis as complications of severe Crohn's disease are rare. Case reports of two young female patients are given who have been treated in 1983 because of peritonitis after perforation of Crohn's disease. The only therapeutic approach making sense is elimination of the intestine affected by the disease and repeated control laparotomies with for treatment of peritonitis and controlling sufficiency of the anastomosis. These patients are at high risk because of treatment with cortisone.
