Ileosigmoid knot.

Ileosigmoid knotting, also known as compound volvulus or double Volvulus, is a rare cause of acute intestinal obstruction. In this condition the ileum wraps around the base of the sigmoid colon and forms a knot. The condition is serious, generally progressing rapidly to gangrene of both ileum and sigmoid colon. Ileosigmoid knotting is an unusual entity in the West, but is comparatively common in certain African, Asian and Middle Eastern nations. Awareness of the condition is essential for prompt diagnosis and optimal management. This article will focus on the etiopathogenesis, presentation, diagnostic modalities, surgical interventions and outcome with review of articles and case reports published till date.
