  22. 22. Types of colonic obstruction:(A) Large bowel distension only, owing to a competent ileocaecal valve. Caecum at risk of perforation. (B) Large bowel distension and small bowel distension—a competent ileocaecal valve leads to caecal distension but also acts as a mechanical obstruction to thesmall bowel. Caecum at risk of perforation. (C) Incompetent distension, small and large bowel dilatation.
