Perianal abscesses cannot heal on their own after they spontaneously rupture and discharge pus, which can lead to the development of anal fistulas. This is mainly due to infection of the anal glands that initially causes swelling and lumps around the anus. Once these rupture and release pus, they can form channels that develop into anal fistulas, causing repeated perianal swelling, pain, and the discharge of pus and blood. In this case, it is advised to visit the proctology department of a hospital as soon as possible for a perianal MRI scan to determine the location of the infection and the direction of the fistula tract, followed by determining the surgical method. After the rupture and discharge of a perianal abscess, a definitive one-time surgical procedure is required to treat the abscess to prevent the potential development of a fistula or a complex, high fistula, which could cause significant damage to the patient and increase the complexity of later surgeries.
