      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Factorial, Purpose: Treatment, Other design features: This study will be conducted as a phase 1 randomized controlled clinical trial in order to check the safety and effectiveness of the treatment method of this study in three groups and with the inclusion of 30 patients (10 patients in each group). During this study, blinding will be done in a double-blind manner, for this purpose, the specialist doctor and the patient will not know about the treatment method used. The groups will be as follows: 1- The first group will receive the conventional seton along with normal saline injection as a control group for the exosome groups. 2- The second group will receive seton plus injection of untreated exosomes (as a control group for treated exosomes). The number of injections in this group will be 1 time. 3- The third group will receive seton plus an injection of treated exosomes. The number of injections in this group will be 1 time, Randomization description: RANDBETWEEN function of Excel software was used for randomization.
In short, cells that contain patients with numbers 1 to 30 with the RANDBETWEEN function [fx = RANDBETWEEN(1, 30)] are selected, and patients are randomly assigned a number based on the mentioned groups. In this way, random numbers 1 to 10 are in the first group, numbers 10 to 20 are in the second group, and numbers 20 to 30 are in the third group, Blinding description: During this study, the data analyst and the clinician will be blinded.
The clinical doctor only received the vial of liquid without the description label, and the patient will be unaware of the type of injected substance (therapeutic or control substance).</study_design>

      <i_freetext>Intervention 1: Intervention group: Seton (conventional treatment method of perianal fistula) plus injection of untreated exosomes-derived placenta mesenchymal stem cells (as a control group for treated exosomes). The number of injections in this group will be 1 time. Intervention 2: Intervention group: Seton plus injection of treated exosomes-derived placenta mesenchymal stem cells. The number of injections in this group will be 1 time. Intervention 3: Control group: conventional seton along with normal saline (as a control group for exosome groups). In order to reduce the difference between the treatment and control groups, it is also necessary to inject normal saline so that the therapeutic effect of the new combined approach can be relied upon.</i_freetext>
