Abstract: Crohn’s disease consists on a complex condition where, despite most patients initially present with an inflammatory behavior, a significant proportion develop complicated lesions such as strictures, fistulas, abscesses, or even perforations. These lesions progressively increase over time and are associated with a higher risk of surgery and hospitalization. Despite significant advances in their management after the introduction of biological therapies, particularly anti-TNF agents, these complications continue to pose challenges for the multiple professionals involved in their care. Fistulas that do not involve the perianal region (entero-enteric, entero-urinary, or entero-cutaneous) require a multidisciplinary strategy that combines medical, interventional, and surgical approaches. Their treatment ranges from general supportive measures to the use of antibiotics or, frequently, advanced therapies. Nevertheless, in cases of certain septic complications or those refractory to medical treatment, percutaneous drainage or surgical intervention remains essential. Although these lesions have a significant impact, evidence regarding the best strategies in this context, as well as the efficacy and safety of different therapies in these patients, remains limited. This is highlighted by the absence of specific recommendations in current guidelines. The objective of this document is to provide a comprehensive overview of non-perianal fistulizing Crohn's disease, addressing its epidemiological, clinical, and therapeutic aspects from a multidisciplinary perspective.
