title: Perianal Crohn's disease.
abstract: Perianal involvement in Crohn's disease is common but often mild and asymptomatic. Medical treatment of more severe disease has met with limited success. The guiding surgical principle in the management of perianal Crohn's disease is the drainage of sepsis and the preservation of sphincter integrity.
