Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract that often leads to intestinal fibrosis, an irreversible complication associated with strictures and the need for surgical intervention. Fibrosis occurs due to prolonged inflammation and abnormal wound healing, involving complex interactions between immune cells, mesenchymal cells, cytokines, and the gut microbiota. Key fibrogenic mechanisms include the activation of fibroblasts and myofibroblasts, cytokine signaling, and disrupted turnover of the extracellular matrix. Advancements in imaging techniques, such as MRI and CT enterography, have improved the detection and monitoring of fibrosis. Additionally, molecular techniques targeting fibroblast activation proteins show promise as a new imaging method. However, there are currently no approved anti-fibrotic therapies for CD. Emerging strategies focus on key pathways and novel therapeutic targets, including growth factor modulators, intracellular enzyme and kinases modulators, and interventions targeting the modulation of inflammation and extracellular matrix, which are being evaluated in preclinical and clinical settings. This review discusses the pathophysiology, diagnostic advancements, and therapeutic perspectives related to intestinal fibrosis in CD, emphasizing the urgent need for targeted anti-fibrotic therapies to prevent long-term complications and improve the life quality of patients.
