Study on the Long-Term Risk of Recurrence of Anoperineal Fistula in Crohn's Disease

Scientific Justification : ● Perianal fistulas are a common and challenging complication of Crohn's disease, significantly impacting patient quality of life. Infliximab, an TNFα antagonist has shown its efficacy in inducing remission of these fistulas. Seton drainage is often used alongside anti-TNF therapy to promote fistula healing and prevent abscess formation. However, data with long term follow up are still lacking on the impact of these treatments. Understanding the long-term outcomes of these combined treatments is crucial for optimizing therapeutic strategies and improving patient management. Treatment Strategy : ● The treatment involves administering infliximab to control inflammation and promote fistula closure, along with seton drainage to maintain fistula patency and prevent abscesses, ensuring continuous drainage and reducing infection risk. Follow-up Description : ● Patients are monitored retrospectively through medical records for a period ranging from several months to years, assessing recurrence rates and potential predictors of recurrence. Follow-up includes regular clinical evaluations, biological evaluations (blood test and fecal calprotectin), colonoscopy, imaging studies such as MRI, and patient-reported outcomes to gather comprehensive data on the long-term efficacy and safety of the combined treatment approach.
