For many patients with anal fissures, having a bowel movement is like torture. Before the torture, you need to encourage yourself repeatedly, concentrate on the 12 points of energy when defecating, try to control every point of force precisely, slowly relax the muscles and slowly increase the abdominal pressure, just like a master of the delicate fight, but the pain is never reduced. How can I cure anal fissure? What is anal fissure? Anal fissure is a common benign disease of the anus second only to hemorrhoids in incidence, mostly seen in young adults and more frequent in women. The symptoms are characterized by periodic pain, bleeding and constipation in the anal canal, mostly in the front and back of the anus, but especially in the posterior position. What are the causes? 1. Presence of anatomically weak areas: The external anal sphincter starts from the tailbone and wraps around along both sides of the anal canal to the anterior confluence, thus the anterior and posterior sides of the anal canal are relatively weak at the confluence of muscle bundles. The broad anal levator muscle is mostly wrapped around both sides of the anal canal and provides strong support to both sides of the anal canal again. The end of the rectum is connected to the anal canal from the back to the front, forming an anal rectangle, and the anterior and posterior sides of the anal canal, especially the posterior wall, are under greater pressure during defecation and are easily damaged. After the anal canal is mostly ligamentous tissue, poor blood supply, once the injury is not easy to repair, and gradually form ulcers. 2, after the injury of infection is the main factor of anal fissure does not heal: due to constipation, foreign body delivery or defecation when too hard to make the local skin of the anus easy to damage, secondary infection and anal fissure. Most of the infections in anal fissures originate from the anal sinus. Eczema dermatitis, anal itching, anal sinusitis, anal papillomegaly, proctitis and other diseases reduce the number of IgA-secreting cells in the anal gland epithelium or lack thereof, flatten the epithelium of the anal gland, reduce the ability to produce mucus, and lose non-specific defense components in the crypt will disrupt the normal local immune mechanism of the intestine, making infection more likely to occur. 3, anal canal stenosis: due to congenital malformation, trauma or surgery caused by the narrowing of the anal canal, dry and hard stool through the anal canal skin tear damage, bacterial invasion and infection formed ulcers, the formation of anal fissure over time. 4, internal sphincter spasm is the main factor of anal fissure pain: some scholars believe that internal sphincter spasm is the cause of anal fissure, but not the consequence of anal fissure [1], that is, the spasm of the internal sphincter first, spasm caused by anal canal high pressure, resulting in defecation difficulties, forceful defecation makes the anal canal skin is torn. Regardless of the cause and effect, anal fissures must be accompanied by painful spasm of the internal sphincter, resulting in the end of poor blood supply, which is an important reason why anal fissures do not heal easily. What are the symptoms? 1. Pain The pain of anal fissure is unique and periodic. When the stool passes through the anus, the anal canal expands, tearing and stimulating the exposed nerves in the fissure, triggering tear-like pain, or a hot sensation, or like a knife cut. The pain directly caused by defecation is reduced or relieved for a few minutes after defecation, called the pain interval. After the interval, there is a more violent wave of pain approaching …… This pain spike is daunting and can last for several hours. The pain is due to the involuntary spasmodic contraction of the anal sphincter after stimulation, and the pain is intense and unbearable. Constipation Most patients with anal fissures have a history of constipation, and constipation and anal fissures are causal and affect each other. Due to the fear of severe pain during defecation, many patients do not defecate, resulting in the stool staying in the intestine for too long, water is excessively absorbed, and the stool is dry and hard. The pain of anal fissure leads to subjective fear of defecation, resulting in a vicious cycle of constipation – painful defecation – withholding defecation – dry stool –The vicious circle of constipation. Blood in the stool is not usually the first reason for patients with anal fissures to visit the doctor. Bleeding from anal fissures is usually small, bright red, dripping or toilet paper stained, or attached to the surface of the stool. Pus, blood and mucus can be seen after infection. Warm tip: The clinical diagnosis of anal fissure is not difficult, but care needs to be taken to distinguish it from tuberculous ulcers of the anal canal, skin cancer of the anal canal, Crohn’s disease complicated by anal fissure, and ulcerative colitis complicated by anal fissure, as these diseases may play a pig in a poke and sow hidden dangers in your body if you are not careful.
