The Current Management of Ileo-Sigmoid Knotting: Narrative Review Article

Ileo-sigmoid knotting is a rare variant of colonic volvulus that presents with acute intestinal obstruction and has a very high risk of gangrene and perforation. The clinical presentation is that of acute intestinal obstruction, and imaging modalities like abdominal radiographs and computerized tomography may aid in its diagnosis. The diagnosis is often made intra-operatively. The treatment of ileo-sigmoid knotting involves surgical management, with the release of the volvulus segment and resection of the segment of ileum that is not viable, followed by an anastomosis. A sigmoid colectomy is also performed, and depending on the viability of the colon, either anastomosis or stoma formation is done. In this review, we will investigate the diagnosis and classification of ileo-sigmoid knotting and also its management.
