Volvulus of the sigmoid colon

Abstract

Abstract The clinical presentation and treatment of 31 consecutive patients with sigmoid volvulus are reviewed. Nearly half of these patients had a history of mental illness and one-third of all patients were chronically constipated. The main clinical features of abdominal pain and gross abdominal distension had been present for an average of 8 days before presentation of the patient to hospital. The clinical diagnosis of sigmoid volvulus was not difficult but the presence of non-viable bowel was more difficult to establish. A silent abdomen was the most valuable indication of the presence of gangrenous bowel. Conservative measures, including sigmoidoscopy and therapeutic barium enema, successfully reduced the volvulus in half of the cases so treated. In those patients undergoing surgery the procedure associated with the lowest mortality was sigmoid resection with end-to-end anastomosis. The overall mortality was 35 per cent.
