Small Bowel Cocoon: A Distinct Disease with a New Developmental Etiology

Abstract

We have treated two patients with small bowel (abdominal) cocoon who presented with acute and partial small bowel obstruction associated with an abdominal mass. Neither had a history of previous surgery, peritonitis, or prolonged drug therapy. The distinct features of this disease are illustrated. A developmental etiology and a new nomenclature for this disease are proposed, along with a review of the literature.
