Summary

The goal of this clinical trial is to assesses the safety of autologous RD2 Ver.02 as compared to a control for managing transsphincteric and intersphinsteric anal fistulas. The main questions it aims to answer are: Assess the safety and efficacy of RD2 Ver.02 in anal fistula application, compared to control. Complication rate by 6 months of anal fistula treatment with RD2 Ver.02 compared to control. Recurrence of anal fistula at 12 months post-treatment Incidence of perirectal infection by 6 months in anal fistulas treated with RD2 Ver.02 compared to control. Patients will be randomized in to 2 arms. For all patients, blood will be drawn to ensure the blinding of the patients, the fistula will be evaluated and debrided, and then the internal fistula opening will be suture-closed, and a water leak test will be performed to ensure sealing. Following the water leak test, In the treatment arm, the patient's own coagulating blood will be applied into the entire fistula tract, allowing it to clot and serve as a provisional matrix inside the fistula tract. In the control arm, the blood sample will be discarded and saline will be applied to the fistula tract.
