After the anal fistula abscess ruptures on its own, some patients can be cured at one time, and some patients need multiple surgeries. If the anal fistula abscess rupture itself, the pus is not discharged, it is best to go to a regular hospital by a professional doctor to clean up the pus, and then local disinfection, medication, etc., covered with medical sterile gauze to protect the wound. Generally, after finding the internal mouth of the anal fistula abscess, you can consider a one-time radical surgery. If the anal fistula abscess is larger and deeper, multiple surgeries should be considered. Therefore, whether an anal fistula abscess can be cured at once after rupturing on its own depends mainly on the scope and depth of the anal fistula abscess. Undeniably, before taking surgical treatment, the pus in the anal fistula abscess must be drained before the next step of treatment. After surgery, we also need to do a good job of local care, keep the wound clean, timely disinfection, dressing change, etc., to avoid infection of the wound.
