Abstract: Multidetector computed tomography is a highly accurate method in evaluating high-grade intestinal obstruction. Closed-loop obstruction is a relatively uncommon subcategory of small-bowel obstruction; however, it is associated with a high risk of vascular impairment and is, therefore, important to diagnose accurately. Closed-loop obstruction is often caused by conditions such as internal hernias, congenital bands, postoperative adhesions, and malrotation. The purpose of this article is to review the imaging features of closed-loop bowel obstruction and various underlying conditions. Special emphasis will be placed on the technique of multidetector computed tomography and its role in diagnosing this entity.
