[Volvulus of the sigmoid colon. Emergency resection and anastomosis].

Eleven cases of sigmoid volvulus in patients aged 76 years in average, without visible signs of necrosis on endoscopy, are reported. All patients were treated within 6 to 48 hours by colic resection and immediate restoration of continuity with a mechanical anastomosis. Morbidity was low, including one case of evisceration and one of pneumonia, and there was no mortality after three months. Early resection seems to prevent the risks of necrosis and recurrence, and to have a good prognosis for survival.
