An anal fistula is an abnormal, inflammatory connection that forms between the anal canal and the skin. In most cases, it develops as a result of an untreated anal abscess. The abscess is caused by an infection, which is often caused by a blockage of the anal canal glands. The formation of a fistula allows secretions such as pus, blood and inflammatory tissue to escape from the internal fistula tract to the outside. This can lead to persistent inflammation and pain. <\/span><\/p>\n There are various types of anal fistulas, which differ in their location and course: <\/span><\/p>\n The development of an anal fistula can take months or even years. It often goes unnoticed for a long time, especially if it starts with a small, superficial abscess. Without adequate treatment, however, a complex system of fistulous tracts can develop, making treatment difficult. <\/span><\/p>\n Understanding the anatomical structures around the anal canal is crucial to understanding anal fistulas. The anal canal is lined with glands that are responsible for regulating moisture and protecting the anal canal. If one of these glands becomes infected or blocked, an abscess can develop, which can be seen in the <\/span><\/p>\n In the worst case, this can lead to a fistula. As the anal canal is surrounded by several layers of muscles, particularly the internal and external sphincters, the course of the fistula can run through or around these muscles. <\/span><\/p>\n The development of anal fistulas can be favored by various factors and pre-existing conditions. In most cases, the cause is a bacterial infection that leads to an anal abscess. If such an abscess is not treated in time, a fistula develops from the accumulation of pus and inflamed tissue. However, there are also a number of other causes and risk factors: <\/span><\/p>\n The symptoms of anal fistula vary depending on the severity and course of the disease. While some patients have only mild symptoms, others suffer from chronic pain and recurrent infections. The most common symptoms include <\/span><\/p>\n Many patients report a constant, unpleasant feeling of pressure in the anal area caused by the inflammation and swelling. This discomfort can become chronic if the fistula is not treated. <\/span><\/p>\n The diagnosis of an anal fistula begins with a thorough medical history and physical examination by a specialist in proctology<\/a>. The doctor will examine the anal area and look for signs of external opening of the fistula or inflammatory processes. Since anal fistulas often run deep in the tissue, additional diagnostic measures are required to determine the exact course of the fistula. <\/span><\/p>\n During the physical examination, the doctor will look for visible signs of a fistula. This may be a small opening near the anus that is leaking pus or fluid. The doctor will often palpate the fistula tract to determine if there is a connection to the anal canal. <\/span><\/p>\n As many fistulas have complex courses, imaging procedures are essential to determine the exact location and course of the fistula. <\/span><\/p>\n In some cases, the doctor may insert a probe into the fistula tract during a short operation to check its course. This method is usually used in conjunction with surgical treatment to fully open and treat the fistula. <\/span><\/p>\n The treatment of anal fistulas depends on the type and severity of the fistula. While smaller and simple fistulas can often be treated conservatively, more complicated or deeper fistulas require surgical intervention. There are various approaches that can be used both conservatively and surgically. <\/span><\/p>\n In some cases, anal fistulas can be treated conservatively, especially if the fistula is small and does not cause severe discomfort: <\/span><\/p>\n However, most anal fistulas require surgical treatment to completely remove the fistula and promote the healing process. The most common procedures include: <\/span><\/p>\n from the inside and treat it with a special instrument. The advantage of this method is that it is very precise and gentle on the tissue. <\/span><\/p>\n In addition to the classic surgical procedures, there are also innovative, minimally invasive techniques that are used in the treatment of anal fistulas: <\/span><\/p>\n\n
