volvulus

Volvulus, vol′vū-lus; n. occlusion of the intestine through twisting.

If the cause of the obstruction is a volvulus, the bowel should be untwisted.

When the large intestine is involved, except in volvulus, the symptoms are generally chronic.

In volvulus involving the sigmoid flexure, when injury to the bowel is great, the symptoms are acute in the extreme.

Volvulus is generally preceded by a history of chronic constipation.
