Colonic perforation in Crohn's disease.
Three cases of acute, free perforation of the colon in Crohn's disease are described and their clinical and pathological features are detailed. Colonic perforation in Crohn's disease bears no definite relationship to obstruction or adrenocorticosteroid therapy. It may occur with or without toxic megacolon, and pathological study has not thus far suggested a common pathogenetic mechanism. Although free perforation has been considered to be extremely rare in Crohn's colitis, it is likely that this complication is more common than previously believed.
