Right colonic adhesions.

Adhesive bands may cause narrowing of the colon. The radiographic appearance may show evidence of a sharp, localized narrowing and smooth mucosal contour. Adhesions involving the ascending colon may also precipitate acute colonic obstruction due to formation of a cecal bascule. The nature of the adhesive bands and their relationship to prior surgery, to anomalies of mesenteric fixation, and to appendices epiploicae are discussed.
