Perianal abscess is an acute purulent infection that occurs around the anorectum. Physical fatigue or weakness, decreased resistance and poor diet are the main causes of localized infections. Patients with leukemia, Crohn’s disease, tuberculosis, and diabetes mellitus are good candidates for complicating perianal abscesses. Many patients have irregular life, lack of sleep, overexertion, or excessive consumption of seafood, spicy food, meat, etc. before the onset of the disease. The main symptom of perianal abscess is anal swelling and pain, which is persistent and not related to stool, and when the pain is severe, the patient may find a lump around the anus or have difficulty in urination. Most people who have perianal abscess have varying degrees of fever and increased white blood cells. Unlike infections in other parts of the body, perianal abscesses have no possibility of self-healing or medication once they occur, and can only be solved by surgical incision or self-collapse. Conservative treatment can only relieve the symptoms and surgical treatment is necessary. Timely treatment of perianal abscess: 1. can prevent the infection from spreading to the whole body and endangering life; 2. can prevent the infection from spreading to the surrounding area and leading to horseshoe abscess and then forming complex anal fistula; 3. can reduce pain; 4. can prevent the anal sphincter from being damaged and affecting the anal function. The purpose of surgery for perianal abscess is to completely incise the abscess cavity, so that the pus flows out, the wall of the abscess cavity is dislodged, and then the abscess cavity is filled by granulation growth, and finally the abscess subsides. A perianal abscess can develop secondary to an anal fistula An anal fistula is a sequelae of a perianal abscess. When a perianal abscess occurs, the source of infection often cannot be accurately located and eradicated due to inflammatory edema of the focal tissue, i.e., there is a fixed source of infection in the anal or rectal cavity, i.e., an internal opening. Most perianal and rectal abscesses break or make incisions outside the anus, and pus flows from the external orifice, but the primary focus of infection is mostly in the internal orifice, the anal sinus. The anal sinus is the portal for continued infection because the opening of the anal sinus is upward and open to the rectal cavity, bacteria and intestinal contents can enter the intestinal cavity through the anal sinus, causing repeated infections, while the lesion is located in the anal sphincter, the diastole and contraction of the sphincter will affect the elimination of pus, and the infection causes fibrosis of the inflammatory tissue to form a fistula. The fistula is often accompanied by a history of painful pus flowing from the paranal area in varying degrees, and after the formation of the fistula, this painful pus flowing from the paranal area will recur from time to time, and if the pus flows poorly, the local and systemic symptoms of acute purulent infection will be manifested. The recurrent episodes of anal fistula can penetrate the canal wall and spread down the sphincter gap to form multiple, complex anal fistulas, which not only makes treatment difficult but also affects the physiological function of the anus. The multiplicity of anal fistulas can form rectovaginal fistulas, rectourethral fistulas and rectal bladder fistulas, endangering the surrounding organs, and there is a possibility of cancer in fistulas that have been untreated or mistreated for years. The only way to achieve a cure is through surgical (including wire) treatment. The perianal abscess prevention advice: Although the perianal rectum is prone to infection and septicemia, it can be prevented if we pay attention to it in general. The way to prevent it is: regular living, diet and combination of work and rest. The actual fact is that you can find a lot of people who are not able to get a good deal on this. The actual fact is that you will be able to get a lot more than just a few of the most popular and most popular items. The most important thing is to have a good understanding of the situation. 2, prevention of constipation and diarrhea is important for the prevention of perirectal abscesses, because dry stools easily rub the anal sinus, plus bacterial invasion and infection. Diarrhea is mostly accompanied by the coexistence of proctitis and anal sinusitis, which can lead to further development of inflammation. 3. Actively treat systemic diseases that may cause perianal rectal abscess, such as ulcerative colitis, Crohn’s disease, etc. Develop good defecation habits and keep the anus clean with warm water sitz bath after daily defecation, which has a positive effect on the prevention of infection.
