Segmental Ulcerative Colitis

Abstract

A of nonspecific ulcerative colitis in which the most distal part of the colon and the rectum initially are uninvolved was described originally by Bargen and Weber,2in 1930, as migratory chronic ulcerative colitis. The condition has been termed right-sided colitis, ulcerative colitis, and type 2 ulcerative colitis. The preferred name at present appears to be ulcerative colitis.
