The old dogmas leading to surgery after failure of medical treatment have recently been overturned, particularly since the advent of anti-TNFs.~Biotherapies now have a central place, including for complicated forms. Previous studies have already looked at the usefulness of anti-TNFs in stenosing forms, or concerning ano-perineal lesions, but what about digestive fistulas.~Indeed, data are scarce, especially in paediatrics.
Crohn's disease is a inflammatory bowel disease evolving towards the destruction of the intestinal wall resulting in stenosing or perforating complications (fistulas, abscesses).~The treatment of perforating Crohn's disease is not codified.
