There is a kind of fever is caused by perianal abscesses Xiao Wang, who lives in Changqing, has recently been busy with work, as the company’s business backbone recently completed a project, the department manager treats everyone to eat seafood, during the meeting Xiao Wang praised by the manager, a happy to drink a few more glasses of wine. The next day, Wang found a feeling of anal swelling, always have the urge to stool, the body is not much strength, feeling limp, a temperature measurement, 38.5 degrees Celsius. The doctor diagnosed Wang as having acute enteritis and hung antibiotics for two days, which had little effect, but his temperature was getting higher. The company’s main business is to provide a wide range of products and services to the market. But the disease did not improve, but worsened, the temperature is also getting higher and higher, blood leukocytes rose to 25 * 10^9 / L, anal swelling, bowel movements are also more and more powerful. After his family brought him to Shandong Hospital of Anorectal Diseases, the attending doctor happened to be Xin Xuezhi, director of the department, who, with years of clinical experience, initially judged that Xiao Wang might have a high-grade perianal abscess. Through anal finger diagnosis and pelvic CT examination, the diagnosis was clear: high-grade perianal abscess. Wang was immediately hospitalized and given emergency surgery to drain the pus. The next day, Xiao Wang’s blood leukocytes dropped to normal levels, his body temperature returned to normal, he was more energetic and his appetite improved, and he was discharged from the hospital a week later. What is high-grade perianal abscess? Perianal abscess, also known as anal canker in Chinese medicine, is an acute purulent infection that occurs around the anus, anal canal and rectum. The main symptom of perianal abscess is redness and swelling along with pain on the side of the anus, which is very intense, persistent and gradually worsens; it is also accompanied by high fever, which can exceed 40 degrees Celsius, and many patients also suffer from poor urination and defecation, poor sleep and insomnia. However, because the location of high perianal abscess is deep, the skin around the anus is not obviously red and swollen, and the distribution of nerves around the anal canal and rectum is not as dense as the perianal area, so the pain is not as strong, and there is even only a vague feeling of anal cramping or bowel movement. Therefore, it is difficult to associate a high perianal abscess with the presence of an inexplicable high fever alone, which can easily lead to misdiagnosis. Because it cannot be seen or felt, high perianal abscesses are also more dangerous, and by the time they are detected, the patient’s local infection is already very serious. Some patients with longer disease duration may also develop sepsis, septicemia, infectious shock, etc., which is life-threatening. Therefore, high perianal abscess can be said to be the “invisible killer” of anorectal diseases. What is the treatment of high perianal abscess? There are not many options for the treatment of perianal abscess, and the only cure is surgery, and the sooner the better. High perianal abscess is more difficult to operate because the location of the abscess is around the anal canal and rectum, which is deep in the body. The difficulty of surgery for high perianal abscesses lies mainly in finding the abscess cavity accurately. Even if the patient has a CT or ultrasound to clarify the location of the abscess, it is a big problem to try to avoid damaging the normal tissues around the patient’s anus during the surgery. For example, if the anal sphincter is damaged during the surgery, the patient may experience fecal incontinence after the surgery; if the anal canal or rectal wall is damaged, it may cause intestinal fistula after the surgery. The anatomy of the human pelvis is very complex, with the digestive tract, urinary tract, reproductive tract, nerves, muscles and blood vessels being densely distributed and intersecting with each other, so without strong anatomical skills and rich clinical experience, it is easy to be dangerous during surgery. Prevention of perianal abscess 1, actively exercise, enhance physical fitness, improve blood circulation, strengthen the body’s ability to resist disease, prevent infection, do not sit still, to avoid long-term local pressure on the anus, causing infection; 2, actively develop good hygiene habits, keep the anus clean, change underwear regularly, adhere to the daily cleaning of the anus after the stool, has a positive effect on the prevention of infection. 3.Actively prevent and control other anal diseases, such as anal sinusitis and anal papillitis, and timely treatment of systemic diseases causing perianal abscess, such as ulcerative colitis and intestinal tuberculosis.
