Recomendaciones del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU) sobre la monitorización, prevención y tratamiento de la recurrencia posquirúrgica en la enfermedad de Crohn

Despite the availability of new, powerful drugs for Crohn's disease, a significant proportion of patients will undergo an intestinal resection to control the disease as it develops. In the absence of an effective preventative treatment, the appearance of new intestinal lesions after surgery for Crohn's disease is the norm; this is known as post-operative recurrence and may appear very early on, even a few weeks after the surgical resection. Furthermore, the drugs that are currently available for the prevention of post-operative recurrence have a limited effect; up to 50% of cases present recurrent Crohn's disease activity despite the preventative treatment, which may require further surgery with the consequent loss of intestinal function, leading some patients to suffer from short bowel syndrome as an irreversible complication. The management of Crohn's disease patients who undergo an intestinal resection should thus be geared towards prevention, early detection and, in the worst case scenario, the treatment of post-operative recurrence. This article reviews the natural history, diagnostic measures, monitoring, prevention and treatment of post-operative recurrence, and proposes recommendations based on existing knowledge.
