A perianal abscess may seem like a scary thing, but if you look into its essence, it is actually the same as an ordinary abscess. Why do I have a perianal abscess? From the above, we know that there are 3 prerequisites for the emergence of perianal abscess: 1. lack of body resistance. That is to say, long-term fat, sweet and heavy food and drink have unknowingly weakened your immunity, so that you are defeated in the face of bacterial infestation; 2, the internal exposure of tissues to the outside. Unlike the extremities, organs and other organs and tissues, the anal canal as the most end of the digestive tube, the exit of excrement, itself is connected to the outside world. Due to the presence of anal sinus and anal glands on the dentate line of the anal canal, there are three ways for bacteria to come into contact with the inside of the tissue: (1) the anal sinus on the dentate line grows like a kangaroo mother’s large pocket (mouth facing up), when the stool passes through the door of the bag there will be some into the bag, the construction of the bag makes it difficult to discharge and reside, the bacteria in the stool begins to erode the anal sinus to form sinusitis. The bottom of the sinus is connected to the anal gland through the anal gland duct, and the bacteria reach the anal gland along this duct, causing anal adenitis. The wall of the anal gland is just a membrane that is easily pierced by bacteria, which can enter the surrounding tissues. The loose perianal tissues are like a maze of twists and turns, and no one knows where the bacteria will go with the pus, so a complex abscess is formed. This is the main reason for the formation of perianal abscesses; attached: (2) Similar to the process in other parts of the body, there is damage to the perianal skin, which brings tissues such as muscles and fascia into contact with the outside world; (3) In addition, the sweat and sebaceous glands of the perianal skin are well developed, and sometimes sebum and sweat hair can become similar to the presence of bacteria after the pores are blocked, causing the corresponding skin inflammation, and when the inflammation spreads inward an abscess may form. However, abscesses caused by the latter two conditions can strictly speaking only be described as abscesses growing in the perianal area rather than perianal abscesses. A perianal abscess is an abscess with an internal opening to the anal canal through the dentate line, which is the first case. In addition, if the pressure in the anal canal is too great due to dry or unformed stools, too long toilet visits, long squatting, sitting and standing, etc., the stool can easily enter the anal sinus, thus causing a series of symptoms later. Will a perianal abscess heal on its own if not treated? Perianal abscesses do not heal on their own and can recur again and again. The surgical treatment of perianal abscess is more complicated, and patients have fear of surgery and ask for “conservative treatment”, which is against the principle of “cutting pus when you see it” in surgery, and because of “anti-inflammatory treatment”. After a few days, although the symptoms of systemic toxicity are reduced, the abscess wall is thickened and the inner mouth is temporarily closed, which can easily lead to the development of abscess to other interstices and turn into complex and intractable perianal abscess and anal fistula. After the occurrence of perianal abscess, it is necessary to seek diagnosis and timely treatment from the anorectal department of a regular hospital. Firstly, the exact scope of the abscess, the perianal space involved and the location of the internal opening should be determined, so as to achieve a one-time cure and avoid multiple surgeries.
