Causes of anal fistula after perianal abscess surgery

Patients with perianal abscess are prone to anal fistula after surgery. In fact, this is a common complication after the treatment of perianal abscess. Therefore, the most important thing is to do a good job of care after the operation to reduce infection or the occurrence of anal fistula as much as possible.

1. Perianal abscess refers to an acute or chronic suppurative infection that occurs in the soft tissue around the anorectum or in the surrounding space, forming an abscess. Perianal abscess is an acute and serious disease in the anorectal department, and is the early stage of anal fistula. If it is not treated for a long time or fails to heal, it is easy to develop into anal fistula.

2. If you suffer from perianal abscess and early surgical treatment is delayed, the infection focus is likely to spread to the surrounding spaces, forming a larger abscess. Pus can spread from the subcutaneous tissue to the ischiorectal fossa, from the affected side to the opposite side through the tissue gaps, enter the anus through the internal and external sphincters, penetrate the levator ani muscles upward into the pelvic cavity to form peritonitis, or erode, ulcerate and penetrate adjacent tissues and organs such as the rectum, bladder, vagina, urethra, etc., forming various types of complex anal fistulas. Once perianal abscess develops into anal fistula, it will cause greater harm to the human body.

3. Perianal abscesses are mostly caused by infection of anal glands and anal sinuses. Whether the perianal abscess ruptures on its own or is drained through a simple incision, the result will most likely be an external opening that remains, often failing to heal for a long time and causing pus discharge and recurrent swelling and pain. This disease is medically known as anal fistula. It can be said that perianal abscess and anal fistula are different stages of the same disease.
