What happens during the procedure?
1. The doctor locates the inside opening of the fistula in the anal canal using a fistula probe and irrigates the tract.
2. The Surgisis AFP plug is pulled into the inside opening. The doctor notes where the plug enters the primary opening and cuts the plug to size.
3. The inside opening is closed by suturing the top tissue layers of the anal canal over the Surgisis AFP plug's head.
4. Finally, the doctor sutures the tip of the plug to the edge of the exterior opening at skin level (optional). The exterior opening is not closed to allow for drainage. The tip of the plug is trimmed at skin level.
