The MRI finding that the 3.8 cm fistula tract is no longer visible is reassuring. However, persistent pus discharge from the external opening means the fistula cannot be considered completely healed, even if the tract is not seen on MRI. Small residual tracts or intermittent infections may not always be visible, especially if the inflammation is minimal at the time of imaging.
The mild swelling in the perineal region without pain may represent:
Mild residual inflammation or scar tissue.
A small collection of fluid.
Persistent low-grade infection.
Based on your description alone, it does not necessarily mean that the fistula is extending to the scrotum. If the fistula were involving the scrotum, you would more commonly notice swelling, redness, pain, or a new opening or discharge over the scrotal skin. An examination by a colorectal surgeon is the best way to determine this.

Health Tips
Keep the area clean and dry, and continue warm sitz baths if they provide relief. Avoid constipation by maintaining a high-fiber diet, drinking adequate water, and avoiding excessive straining during bowel movements. Good hygiene can reduce irritation but will not eliminate a persistent fistula if one remains. Thank you
