Anal fissure is a very troubling anorectal disease, many patients suffering from anal fissure are suffering from blood in the stool and pain, so how to treat anal fissure and what tests need to be done for anal fissure? This is a question that many anal fissure patients would like to know, so below we answer the question of what tests need to be done and how to treat anal fissures. What tests are needed for anal fissure? The examination items of anal fissure mainly include: anal visualization, rectal diagnosis and anoscopy. 1.Anal visual examination: use two thumbs to gently separate the patient’s buttocks to observe whether there are prolapses, external hemorrhoids, fistulas, abscesses, anal fissures, etc. in and around the anus. 2, rectal finger diagnosis: also known as anal finger examination, the examiner wears gloves on the right hand or the right index finger with a finger sleeve, coated with lubricant, and puts the front of the right index finger on the anal opening, and then gently inserts it into the anal opening after the patient gets used to it, first testing the tightness of the anal sphincter, and then examining the anal canal around the rectum in turn, paying attention to the presence of tenderness, lumps, fluctuations and stenosis around the intestinal wall. In the anterior rectal wall, men can look for the prostate gland, and women can touch the cervix, and when the finger is withdrawn, observe whether there is blood and mucus on the glove. 3, anoscopy: anoscope coated with lubricant, slowly inserted into the anus, pull out the core, to a good light, from deep to shallow observation of rectal mucosa color, rectal flap, the presence of ulcers, polyps, tumors, foreign bodies, etc., the anoscope slowly outward, while retreating to observe the rectum and the tooth line near the presence of lesions, such as the inner mouth of the fistula, hemorrhoids. What is the treatment for a diagnosed anal fissure? Mild anal fissures are treated with drug therapy. For severe old anal fissures, the hospital uses HCPT minimally invasive surgery, which is operated with the HCPT, a fully computerized multifunctional anorectal treatment system, which has high-frequency capacitive field anal fissure treatment, high-frequency electric knife and capacitive field hemostatic clamp function. The treatment process is less painful, less bleeding, fast, and has a very low recurrence rate after treatment. This minimally invasive treatment is to use the rectal fiberscope to enter inside the anus, through the monitor, directly to the inner mouth of minimally invasive electrocoagulation, so that the inner mouth of the anal fissure dry and closed, and then wash the pus inside the fistula, so that the bacteria and fecal water inside the stool can not enter the surrounding tissue, thus blocking the source of infection and pain, to achieve the treatment effect. The actual fact is that you can find some of the symptoms of the disease, must be timely to the professional anorectal hospital for examination and treatment.
