Anorectal Crohn's disease.

Anorectal disease affects many patients with Crohn's disease. Clinical manifestations vary from asymptomatic skin tags to severe, debilitating perineal destruction and sepsis. Surgical management needs to be conservative and must focus on draining septic sites, preserving sphincter function, and palliating symptoms. Medical management has had some success in improving symptoms, but as yet, it has not been able to ameliorate most perianal complaints quickly and enduringly. Many new and exciting treatment modalities are being investigated with the hope that more effective approaches to these complex and difficult problems can be realized.
