How does TCM treat anal fistula?

The treatment principle of anal fistula should be based on the mechanism of anal fissure and the anatomical structure of anal fistula.

① Internal orifice resection: The key to the treatment of anal fistula is to find the primary internal orifice and remove the infected anal sinus, anal gland and its catheter.

② Treatment of fistula, branch pipe and dead space: clean fistula, branch pipe and dead space to avoid postoperative recurrence.

③ Preservation of anorectal ring: During anal fistula operation, we should make a clear diagnosis, find out the direction of internal orifice and fistula, and preserve anorectal ring to maintain the normal function of anal contents.

In short, in the specific operation, we must carefully look for the internal orifice to prevent cutting off the anorectal ring.
