Rare synchronous caecal and sigmoid volvulus: management of two cases

Abstract

Abstract Colonic volvulus is one of leading causes of large bowel obstruction following colorectal cancer and diverticulitis, accounting for 5% of cases. Sigmoid volvulus is most common (75%) followed by volvulus of the caecum (15%), transverse colon (3%) and splenic flexure (2%). Synchronous volvulus of the caecum and sigmoid is very rare, with six reported cases in the literature to the best of our knowledge. We report two cases within 6 months. The key learning points include that classical radiological signs of both caecal and sigmoid volvulus may not be present, and that prompt, definitive management is necessary to prevent recurrence and morbidity.
