Idiopathic cocoon abdomen with congenital colon malrotation: a case report and review of the literature

Abstract Background Cocoon abdomen is a relatively rare abdominal disease characterized by the total or partial encasement of the small intestinal by a dense fibro-collagenous membrane. Case presentation We reported an unusual case of idiopathic cocoon abdomen with congenital colon malrotation. Laparotomy and sac release were performed on the patient. The patient was no recurrence 6 months after operation. A literature review was also performed. Conclusion Preoperative diagnosis of abdominal cocoon is difficult. A careful history, physical examination and appropriate radiology may be helpful in making a definitive diagnosis. If conservative treatment can’t relieve symptoms effectively, surgery is currently considered to be important in the management of this disease.
