NCT05709717

Brief Summary

Consecutive patients with complex anal fistula were prospectively followed for 12 months. Routine MRI was performed before and at 4 and 12 months after surgery. Continence was assessed likewise using a validated questionnaire. Fistula were drained with setons prior surgery. SVF was harvested from subcutaneous abdominal fat and PRP from peripheral blood. Distal fistulectomy to the sphincter was performed and the wound left open, while the internal orifice was closed. SVF-PRP was injected around the fistula. Patients showered their excision wound until dry. Outcomes were reported as median \& interquartile range (IQR)
