Comparison of primary resection and anastomosis with Hartmann’s procedure in management of acute sigmoid volvulus

Background Sigmoid volvulus is a common surgical emergency in many regions of the world that carries significant morbidity and mortality. Volvulus occurs when an air-filled segment of the colon twists about its mesentery. In developing countries, it is a major cause of colonic obstruction. The sigmoid colon is involved in up to 90% of cases. It can be present as acute, sub-acute or chronic. Acute sigmoid volvulus requires emergency surgery. Various methods are used in its management.
