Some patients have been diagnosed with anal fistula, but they delayed treatment because they were afraid of the pain of surgery, causing their condition to worsen, affecting their normal work and life, and causing great physical and mental pain. The first thing you need to do is to have an anal fistula, but you need to have an anal examination to confirm the diagnosis. What is an anal fistula? Anal fistula, also known as anal leakage, is short for anorectal fistula. It is named after the form in which it develops. This is because the main symptom is the repeated flow of pus or pus and blood from the sores on the skin around the anus, or even the flow of feces, which the ancients thought was like a house with a broken roof that leaks when it rains, so they called it a leak. A fistula should have one or several interconnected pipes inside and outside the body, which can discharge pus and secretions from the body to the outside. The folk call it a fistula according to its symptoms, and the disease of pus and blood or fecal water flowing from the sores on the skin around the anus is imaginatively likened to a fecal rat hiding inside the sores, hence the common name “fecal rat”. The fistula, once formed, has very little chance of healing itself, and if it is not treated in a timely manner, repeated episodes can easily complicate the fistula and bring a lot of trouble and certain harm. The actual fact is that you can find a lot of people who have been in the business for a long time. As a result of repeated episodes, pus can penetrate the wall and spread along the sphincter to form a branch, developing into a complex anal fistula, which not only makes treatment difficult, but also affects the normal physiological function of the anus. The repeated attacks of anal fistula can form rectovaginal fistula, recto-urethral fistula and recto-vesical fistula, which endanger the surrounding organs. Moreover, fistulas have a tendency to become malignant. Therefore, once an anal fistula occurs, it should be treated in a regular hospital anorectal specialist to avoid delaying the condition and causing adverse consequences. How to treat anal fistula? The first thing to do is to make a clear diagnosis and find out the location of the internal and external ports and tubes, and then use Chinese medicine for treatment. The first thing that you need to do is to use advanced science and technology, such as ultrasound and MRI, to investigate the fistula and provide an objective basis for treatment.
