Abstract

Abstract: Colonic volvulus accounts for approximately 5% of cases of large bowel obstruction. Sigmoid volvulus is commonest (75%), followed caecal volvulus (15%). Synchronous volvulus of the caecum and sigmoid is rare, with five reported cases in the literature. We report two cases in a London teaching hospital managed within 6 months. Both male patients (aged 72 and 79 years) had presented to the emergency department on multiple occasions (2-5 times in the preceding 1-8 months), with obstructive symptoms including tender abdominal distension and constipation. On all occasions, sigmoid volvulus was diagnosed based on plain abdominal films and flatus tubes were inserted, with initial clinical resolution. On their final presentation, both patients were admitted for definitive surgery. CT scans of the abdomen and pelvis were consistently reported as showing only sigmoid volvulus. Only intra-operatively was the diagnosis of synchronous caecal and sigmoid volvulus appreciated. Complete symptom resolution was achieved with subtotal colectomy and ileostomy formation. The key learning points from these cases are: 1) synchronous large bowel volvulus is a rare and easily missed diagnosis, 2) conservative management is unlikely to be successful, 3) radiological appearances may only suggest one type of large bowel volvulus and 4) definitive diagnosis is made intra-operatively.
