hemorrhoids and anal fissures,Prevention and treatment of anal fissure

    What is anal fissure? As the name suggests, anal fissure is a crack in the anus. The professional concept is that the skin of the anal canal below the tooth line of the anus, prismatic cracks or ulcers formed due to a variety of reasons. The direction of the slit is parallel to the longitudinal axis of the anal canal and is fusiform or elliptical. The incidence of anal fissure accounts for the second place in anorectal diseases, second only to hemorrhoids. The prevalence of young adults is 20-40 years old. According to statistics in China, there are more men than women. The vast majority of anal fissures are located on the posterior midline of the anal canal, and can also be on the anterior midline, with very few anal fissures on the side. If there is an anal fissure on the side, the possibility of intestinal inflammatory disease or tumor should be considered. Long-term untreated anal fissure will seriously affect the life of the patient, and will also induce anorectal diseases such as perianal eczema, anal itching, and more serious, cancer may occur. Causes of anal fissure Many people often experience symptoms of constipation, pain after defecation, and bleeding. People often think it is hemorrhoids. However, patients with such symptoms often get anal fissures instead of hemorrhoids. So, what is the cause of anal fissure?

    1. Constipation: Constipation is one of the most important causes of anal fissure. If the patient has frequent constipation and dry stools, it will inevitably damage the anal canal when passing through the anal canal, causing anal fissure. In addition, if the patient does not cure the constipation during the treatment of anal fissure, anal fissure will be induced again in the future, leading to recurrent anal fissures.

    2. Poor defecation habits: Many people have the habit of reading newspapers and smoking during defecation, which invisibly prolongs the defecation time, aggravates the pressure on the anal area, and causes blood stasis in the anal area. If you defecate hard at this time, the anal canal will be excessively compressed, which will cause anal fissure bleeding.

    3. Infection factors: If there are long-term infection factors around the anal canal, it will cause the anal fissure to recur and continue to heal. These infectious factors mainly include various anorectal diseases such as hemorrhoids, perianal abscess, anal fistula, and anal sinusitis. Two typical symptoms of anal fissure

    1. Periodic pain: Pain is the main symptom of anal fissure. Most of the painful symptoms of anal fissure are severe and have typical periodicity. Burning or cutting pain in the anal canal during defecation is called pain during defecation. It is relieved a few minutes after defecation, which is called intermittent period, and then the anal sphincter spasm is painful again, which can last for half to several hours. It is clinically called sphincter contracture pain until the sphincter is fatigued. After relaxation, the pain is relieved. Pain occurs again during defecation, which is called anal. Crack pain cycle.
