How did a pack discharge grow beside anus to treat

The patient has anal abscess. If the abscess belongs to long-term repeated ulceration and purulent discharge, it may be caused by anal fistula. At this time, after anorectal color Doppler ultrasound exploration, it can be found that the ulceration is connected with the inside of the anus and rectum. For the treatment of anal fistula, the best way is to perform surgery. The internal opening is fully explored during the operation, and the fistula is removed.

After anorectal color Doppler ultrasound exploration, it is found that the abscess is not connected with the rectum. It is considered to be sebaceous cyst. For the treatment of this disease, it can be externally applied with arnebia ointment for swelling and pus extraction. If the effect is not good, surgical incision can be performed.
