Multiple abdominal cocoons: an unusual presentation of intestinal obstruction and a diagnostic dilemma. Case Rep Surg. 2015;2015:282368. [PMID: 25893128 PMCID: PMC4393895 DOI: 10.1155/2015/282368]

Abdominal cocoon - A rare etiology of intestinal obstruction

Abdominal cocoon is one of the rare causes of intestinal obstruction. It is referred as complete or partial small bowel encapsulation caused by the thick fibrocollagenous membrane. It is most common in young adolescent girls. We present a 40-year-old male patient with idiopathic abdominal cocoon. Few cases of male patients suffering from idiopathic abdominal cocoon have been reported in literature.

Idiopathic abdominal cocoon syndrome with unilateral abdominal cryptorchidism and greater omentum hypoplasia in a young case of small bowel obstruction

Abdominal cocoon syndrome (ACS) is a rare cause of intestinal obstruction due to total or partial encapsulation of the small intestine by a fibrocollagenous membrane. Idiopathic ACS with abdominal cryptorchidism and greater omentum hypoplasia is even rarer clinically. We successfully treated a 26-year-old male case of small bowel obstruction with acute peritonitis. He was finally diagnosed with idiopathic ACS with unilateral abdominal cryptorchidism and greater omentum hypoplasia during exploratory laparotomy. He then underwent enterolysis, cryptorchidectomy, and appendectomy. He recovered gradually from the operations and early postoperative inflammatory ileus. There has been no recurrence of intestinal obstruction since the operation, and he is still in follow-up. We analyzed his clinical data and retrospectively reviewed the literature, and our findings may be helpful for the clinical diagnosis and treatment on ACS.
