What is the difference between perianal abscess and anal fistula

The occurrence of perianal abscess and anal fistula are both relatively serious phenomena, so we should also understand the difference between perianal abscess and anal fistula. Perianal abscess is a common anorectal disease, so we need to distinguish them by their symptoms.

1. Diseases that cause anal pus discharge include perianal abscess, anal fistula and furuncle. The pus is sometimes green, but mostly yellow. When a boil or wound becomes festered, the pus usually has a special smell. So, what are the differences between perianal abscess and anal fistula? The following is some relevant introduction by the editor. The difference between perianal abscess and anal fistula Perianal abscess: Acute suppurative infection occurs in the soft tissue around the anal canal and rectum or in the surrounding space, and an abscess is formed, which is called perianal canal and rectal abscess.

2. Its characteristic is spontaneous rupture, or the formation of anal fistula after surgical incision and drainage. It is a common anorectal disease and also the acute stage of the anal canal and rectal inflammatory pathological process, while anal fistula is the chronic stage. Anal fistula: Anal fistula is a sinus tract formed with the anus as the center. Pus repeatedly flows out of the small holes in the skin around the anus and is generally painless. Anal fistula is mostly a sequela of perianal abscess. Because it is painless and not treated actively, it often recurs and causes pain due to perianal abscess.

3. In addition, because pus discharge causes inflammation of the perianal skin, the perianal skin must be kept clean at all times, otherwise anal fistula cannot be treated. The difference between perianal abscess and anal fistula is that other hemorrhoids can be cured by lifestyle therapy, or at least most of them can be improved by lifestyle therapy. Unfortunately, only anal fistula cannot be cured by lifestyle therapy, and surgery is the only cure. Therefore, surgery should be performed as soon as possible. In addition, the differentiation between anal fistula and atheroma infection and pyoderma is also relatively simple.

4. However, it is difficult for an outsider to distinguish the three, including boils, so it is best to ask a doctor for diagnosis and treatment. Treatment of perianal abscess and anal fistula: A few perianal abscesses can be dissipated by antibiotics, hot water sitz baths and local physical therapy, but most require surgical treatment. There are two types of surgery. Since most perianal abscesses require surgical incision and drainage, it is important to pay attention to some contraindications in the treatment of perianal abscesses.
