Anal (or anorectal) fistulas are abnormal passages that form between the anus or rectum and the skin around the anus. They are often caused by an infection in an anal gland, which can lead to the formation of an abscess. If left untreated, the abscess can rupture and form a fistula.
Depending on the severity and complexity of the fistula, several surgical and non-invasive treatment options are available in Turkey.
