Endoscopic Evaluation and Management of Perianal Disease

Abstract

Perianal Crohn's disease is associated with decreased quality of life, high morbidity, and high health care use. Treatment goals are to provide infection control, stop fistula drainage, and heal fistula tracts while preserving the anorectal sphincter. Treatment includes a combination of medical and surgical intervention, but new techniques are using interventional endoscopy to act as either a bridge to surgery or to decrease the need for surgical intervention. The decision on which approach to pursue requires knowledge of prior surgery, altered anatomy, prior fistula treatment, and imaging and endoscopic evaluation of fistula complexity, mucosal involvement, and associated stricture or abscess.
