2. Explore the incision position, observe the position and shape of the external opening, and estimate the direction and depth of the fistula. First, use the probe to gently probe from the outer opening along the tortuous direction of the fistula, passing through the entire fistula to reach the inner opening. During exploration, you can insert a finger into the anal canal and feel where the probe passes. After the tip of the probe passes through the internal opening, you can clamp the tip with hemostatic forceps, or bend the probe so that the tip passes through the anus to prevent the probe from slipping. If the internal opening cannot be found, a piece of dry gauze can be inserted into the rectum, and 2 to 3 ml of methylene blue can be injected from the external opening. The gauze can then be removed and the position of the methylene blue staining can be observed to determine the position of the internal opening, and then the probe can be inserted.

3. Cut the fistula from the inner opening to the outer opening, and cut the rectum and anal canal walls of the entire fistula along the direction of the probe to open the entire length of the fistula.

4. Make an incision on the skin on both sides of the open fistula for all fistulas, continue to go deeper along the incision, with the cut surface obliquely toward the deep layer of the fistula, and remove the entire fistula. If there are fistula branches, all methylene blue-stained tissue or scars should be removed until normal tissue is exposed. The cross section of the wound is V-shaped.

5. Stop bleeding by compression, ligation or suture.

6. Trim the wound edges and remove part of the skin at the wound edge, trim it neatly, leave the wound open, and place Vaseline gauze for drainage.
