Ileosigmoid knotting: An unusual cause of intestinal obstruction.

Ileosigmoid knot or double volvulus is an unusual cause of intestinal obstruction and presents as a surgical emergency. It affects men of middle and old age. It occurs due to entangling of ileal and sigmoid loops producing obstruction and strangulation. Here, We have described a case 60 years old male presented with features of intestinal obstruction. Emergency laparotomy revealed ileosigmoid knotting with gangrene of involved segment. Resection of unviable portion with knot was done with double primary anastomosis and covering ileostomy.
