Non-surgical therapy: including internal therapy and external therapy. (1) Internal treatment (see TCM therapy for details) (2) External treatment 1. External washing method: For local swelling and pain, the decoction of Sophora flavescens can be added or subtracted, and the decoction can be smoked and washed while it is hot. 2. External use method: In the acute stage of anal fistula, you can take hemorrhoid ointment from the local doctor's home for external use. Cryotherapy is very common in the treatment of anal fistula, which mainly refers to granulomatous ducts around the anus with internal and external openings. The external orifice is located on the perianal skin, and the internal orifice is located in the anal canal or rectum. Most anal fistulas are caused by abscesses around the anorectum. Its main manifestation is that a small amount of purulent, bloody and mucinous secretions often flow out of the fistula. Cryotherapy is not difficult to treat anal fistula, which is beyond the reach of some simple physical therapies. 1. Cryotherapy is suitable for the treatment of low simple anal fistula, and liquid nitrogen at-196 degrees Celsius is used to coagulate and necrosis the fistula. Then it falls off, forms a new wound and heals itself. Under anesthesia, the fistula was properly scraped from the external orifice with a curette, then the probe was inserted to determine the direction and trend of the fistula, and then the probe was pulled out, and a similar cryoprobe (copper tube with different bending degrees, with a diameter of about 2 mm) was selected for contact freezing and frozen for 3 minutes, so that the whole tube became a white popsicle. After natural rewarming, the probe was pulled out, anti-inflammatory and analgesic ointment was applied externally, and the dressing was changed in hip bath after operation. This method is simple, painless, without bleeding, anal incontinence and other complications. 2. Electrotherapy is based on the principle of traditional Chinese medicine thread-drawing therapy [2], using the high-temperature physical technology of modern anal fistula electrotherapy, using arc discharge to generate high temperature, burning local tissue to cut anal fistula, and achieving the purpose of treatment. Suitable for the treatment of low anal fistula. Under anesthesia, the probe was used to find out the internal and external opening and direction of fistula, and electrotherapy instrument was used to cut the anal fistula wall in turn along the probe to expose the wound surface, and scald ointment was applied externally. This method is simple in operation and short in course of treatment, and can be cured by electrotherapy once.

Self-care of patients with anal fistula is particularly important, which can not only improve the stimulation of local adverse environment, but also provide a good foundation for treatment and rehabilitation. Pay attention to the cleanliness and hygiene of anus in remission period, and often wash anus with warm salt water, or wash it with alum water, or wash the part with potassium permanganate solution at least once a night, which can not only clean local hygiene, but also improve local blood circulation, enhance resistance to diseases and reduce inflammatory reaction. When the secretion of anal fistula increases, the underwear should be washed and changed frequently, and the secretion should not be accumulated in the affected area. During the attack, the external orifice can be surgically enlarged to drain pus, which can not only relieve the swelling pain, but also prevent the pus from spreading to other parts. In a word, taking appropriate health care measures can control the development of diseases and reduce the suffering of patients. 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 during operation 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, preserve anorectal ring and maintain normal anal containment function. In the specific operation, we must carefully look for the internal orifice to prevent cutting off the anorectal ring. Treatment scheme Anal fistula cannot heal itself. Without treatment, perianal abscess will recur and must be treated surgically. The principle of treatment is to cut the fistula to form an open wound and promote healing. There are many surgical methods. The operation should be performed according to the position of internal orifice, fistula and anal sphincter.
