Ileosigmoid Knotting: A Rare Cause of Intestinal Obstruction and Bowel Ischemia—Case Report with Literature Review

Ileosigmoid knotting, also known as compound volvulus or double volvulus, is a rare surgical emergency causing intestinal obstruction. Principally, it is a closed-loop intestinal obstruction that involves the sigmoid and ileum. It is considered a rare cause of intestinal obstruction. Differentiation of ileosigmoid knot from simple sigmoid volvulus is important because endoscopic decompression in ileosigmoid knot might be hazardous and even fatal. Endoscopic decompression of ileosigmoid knot may lead to perforation or injury. The mortality rate of ileosigmoid knot in general may reach 48%. We present a case of a 30-year-old male patient who presented with ileosigmoid knot at our emergency room. The aim of reporting this case is to increase understanding of the condition to promote earlier diagnosis.
