Appendiceal tie syndrome.

Intestinal knot syndromes such as ileosigmoid knots, ileal-ileal knots have been described in the literature. We describe a case of a long inflamed appendix wrapping around a loop of ileum causing an appendico-ileal knot, a rare form of closed loop obstruction with only five cases reported previously. The use of CT scanning prior to surgery is discussed and literature reviewed.
