Volvulus of the gastrointestinal tract

Abstract

Volvulus describes the twisting of the intestine or colon around its mesentery. Intestinal obstruction and/or ischaemia are the most common complications of volvulus. Within the gastrointestinal tract, there is a preponderance towards colonic volvulus. The sigmoid is the most commonly affected segment, followed by the caecum, small intestine and stomach. Distinguishing between the differing anatomical locations of gastrointestinal volvulus can be challenging, but is important for the management and prognosis. This article focuses on the main anatomical sites of gastrointestinal volvulus encountered in clinical practice. The aetiology, presentation, radiological features and management options for each are discussed to highlight the key differences.
