Perianal Crohn ’s: Review of Endoscopic and Cross-Sectional Imaging

Crohn ’s disease has many manifestations and can affect any aspect of the gastrointestinal lumen. In this chapter, we will review perianal manifestations of Crohn’s disease which includes the formation of fistula tracks, strictures and abscesses. Perirectal fistulas can be particularly challenging to manage due to the complexity in diagnosis. Additionally, clinical symptoms of perirectal disease do not always reflect disease activity. Perianal fistulas are important to diagnose early and accurately due to associated complication of abscess formation.
