Patients with anal fissure should first try to keep their stools dry and pay attention to defecation on time every day. Pay attention to eat more vegetables, fruits and foods rich in plant fiber, such as sweet potatoes, and drink a cup of honey water on an empty stomach every morning to prevent dry stool and constipation.

For the treatment of anal fissure, we must first distinguish the course of the disease and treat the symptoms according to different situations. Anal fissure is generally divided into two types in clinic.

(1) Early anal fissure: the onset time is short, and there is only a small spindle ulcer on the skin of anal canal. The wound is shallow, bright red, with neat and elastic edges, no scars and induration, short course of disease and easy to cure.

(2) Chronic anal fissure: the early anal fissure continued to be infected and was not properly treated. Due to frequent contraction of sphincter, the wound drainage is not smooth, so the edge becomes hard and thick, and the perifissure tissue is inflamed, congested and edematous, which blocks the superficial vein and lymphatic reflux, causing edema and connective tissue hyperplasia, forming redundant external hemorrhoids. Anal sinusitis and anal papillitis are complicated near the tooth line at the upper end of the fissure, resulting in single mouth leakage and anal papilla hypertrophy. The ulcer base stimulates connective tissue proliferation due to inflammation, and the comb-like membrane thickens and hardens to form a comb-like membrane band, which hinders sphincter relaxation, resulting in irregular crack margin and lack of elasticity, forming a deep and large ulcer that is difficult to heal. Anal fissure, comb belt, external hemorrhoid, internal fistula, anal sinusitis, anal papillitis, anal papilla hypertrophy and other diseases are the characteristics of chronic anal fissure.

In clinical treatment, different treatment schemes should be adopted according to the specific situation of anal fissure.

For mild anal fissure and early anal fissure, external use of anti-inflammatory ointment (Anshi injection therapy if possible) and fumigation with traditional Chinese medicine (or sitting bath with very light potassium permanganate warm water) can be used for treatment.

For patients with severe anal fissure, surgery is needed for thorough treatment, and the simplest method should be used to obtain the best effect when treating anal fissure. An open incision can be made directly at the anal fissure mouth, combined with high-frequency electrocoagulation of HCTP minimally invasive technology, which not only avoids the hidden danger of postoperative bleeding and infection, but also accurately grasps the depth and scope of incision, which can be said to be multi-purpose.
