Perianal fistulizing Crohn's disease (PFCD) represents a challenging and complex disease phenotype. Patients typically suffer a more severe disease course than those without perianal complications and are often managing debilitating symptoms. Etiology is understood to be multifactorial, with genetic predisposition, microbiological insult, aberrant immunity, and mechanical factors all implicated. As a result, multimodal treatment strategies must be employed to achieve disease control and fistula closure. This requires the complimentary involvement of medical and surgical disciplines in order to ensure thorough assessment and treatment tailored to the individual scenario and patient goals. The aim of this article is to describe an overview of the various treatment strategies available for PFCD, focusing on how a synergistic approach is required to ensure maximal chances of success.
