After the perianal abscess breaks, the patient must have timely surgery, because the perianal abscess breaks does not mean that the perianal abscess has healed, it just means that the condition of the perianal abscess further develops, and an anal fistula is formed in the local area, and the anal fistula is usually more serious than the perianal abscess, so the patient must have timely surgery, to avoid the formation of anal fistula in the perianal abscess, which will lead to not be able to heal. To find the inner and outer mouth of the anal fistula, cut the channel, keep clean and dry, so that the channel is completely occluded, in order to effectively avoid postoperative anal fistula recurrence. It is important to keep stools soft after surgery to avoid dry stools, which can lead to the formation of anal fissures after surgery.
