Perianal fistulizing Crohn's disease: Mechanisms and treatment options focusing on cellular therapy.

World J Gastroenterol

March 2025

Department of Anatomy, Division of Human Biology, School of Medicine, IMU University, Kuala Lumpur 57000, Malaysia.

Perianal fistulizing Crohn's disease (PFCD) is a common presentation of CD, which affects the patients' quality of life, including social and sexual function. The management of PFCD remains a critical challenge in inflammatory bowel disease, primarily due to limited understanding of the mechanisms involved in its pathogenesis, complicating medical treatment. Increased production of inflammatory cytokines such as tumor necrosis factor and interleukin-13 by infiltrating macrophages and other inflammatory cells stimulate the epithelial-to-mesenchymal transition, resulting in activation of myofibroblasts and elevation of matrix metalloproteinases, leading to fistula formation.
