Patients can live with a fistula for life. Anal fistula is a benign disease that has a certain chance of becoming cancerous, but the chance of such cancer is very small. For patients in poor health, such as those who are older, have severe cardiovascular disease or organ failure such as severe kidney failure, it is generally recommended that they live with the fistula. This is because some of the accidents and risks that may arise if you have anal fistula surgery are higher. However, for patients who are healthier and in better physical condition, it is generally recommended that patients undergo anal fistula surgery. Because the existence of anal fistula itself can affect the quality of life of an individual, often producing pus, pus and blood, pain, and a certain risk of cancer over time, surgery is recommended if available. If you are in poor health, you can also survive with a fistula for life.
