Sclerosing encapsulated peritonitis or abdominal cocoon is a rare disease that is characterized by a total or partial encasement of the small bowel by a thick and fibro tic membrane. Thirty eight cases were reported since it was first described. It occurs primarily in adolescent females in tropical and subtropical regions. Preoperative diagnosis is a matter of challenge and usually made at laparotomy. We report a patient with partial intestinal obstruction and abdominal co-coon that was diagnosed during surgery. We review the literature and discuss the etiology of this disease.
