Patients may develop fistulas due to Crohn's disease or as a postoperative complication after restorative proctocolectomy with ileal pouch anal anastomosis. Unfortunately, the treatment of fistulas can be challenging. The current standard of care may include medical therapy and/or surgical intervention. However, endoscopic treatment for postoperative pouch complications has emerged as a valid alternative option. We describe a case of persistent drainage from a Y-shaped entero-entero-cutaneous fistula that resolved after endoscopic fistulotomy with needle knife.
