[Ileosigmoid knot is an unusual and severe cause of bifocal bowel strangulation].

Ileosigmoid knot is an unusual and severe cause of bifocal bowel strangulation. Prompt surgery is necessary to prevent widespread intestinal infarction and high mortality rate. We report a clinical case and present a literature review to precise the features that should lead to prompt preoperative diagnosis. There are no clinical features specific for this diagnosis. Abdominal CT scan with contrast enema appears to be the fastest way to show the association of small bowel ischemia and sigmoid volvulus that signs ileosigmoid knotting.
