[Endoscopic resolutions of volvulus of the sigmoid colon].

The flexible colonoscope has brought considerable advantages to the diagnosis and nonsurgical treatment of volvulus. In the case of repeated recurrences that make surgery vital because of the onset of signs of vascular trouble on the twisted ansa, preoperative resolution permits correction of hydroelectrolytic imbalances and the preparation of the colon with the possibility of operating with no need for protective colostomy. It also allows resolution of the acute situation in the presence of contraindications to intervention.
