One-stage procedure in the management of acute sigmoid volvulus.

In a descriptive prospective study, twenty-seven patients with sigmoid volvulus and three with ileosigmoid knotting had primary resection of the redundant sigmoid colon with immediate anastomosis after intraoperative antegrade colonic irrigation. There was no clinical anastomotic leak nor mortality in any of our patients. Superficial wound infection occurred in four patients (13.3%). Intraoperative colonic irrigation time ranged between 25 to 50 minutes with a volume of saline/Hartmann's required to achieve a clean colon ranging between 1.5 to 5.0 litres. The duration of hospital stay ranged between 7 and 14 days. The result of this study suggests that resection of acute sigmoid volvulus and primary anastomosis after antegrade intraoperative colonic lavage is safe provided the patient is reasonably fit.
