The endoscopic spectrum of segmental colitis associated with diverticulosis.

Objective  An endoscopic classification of ‘Segmental colitis associated with diverticulosis’ (SCAD) is lacking. Our aim was therefore to assess the endoscopic spectrum of SCAD, comparing it with the histological and clinical features. Method  A prospective study was performed from January 2004 to October 2007.
