Abstract
Redundant colon, also referred to as "dolichocolon," is an anatomical variant associated with elongation and redundancy thought to be associated with constipation, abdominal pain, and distention.1,2 Diagnosis requires radiological visualization of the non-dilated colon in situ via barium enema or abdominopelvic computed tomography (CT). Colonic redundancy is based on 3 criteria: sigmoid loop displaced cranially relative to the iliac crests (type 1); transverse colon caudal to the iliac crests (type 2); and redundant loops at the hepatic or splenic flexure (type 3).2 Rarely, dolichocolon may meetall 3 criteria.2.
