Abdominal cocoon with small bowel obstruction: two case reports.

Abdominal cocoon is a rare condition that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a fibrocollagenous membrane. Treatment is surgical resection of the membrane and free the bowel. Preoperative diagnosis is possible with combination of sonography and CT scan. We report two cases where the diagnosis of abdominal cocoon was suggested preoperatively based on the sonography and CT scan of abdomen.
