Perianal abscess is a common disease in proctology, generally involving an infection of the local anal crypts and submucosal tissues near the anus. When a perianal abscess acutely flares, it is necessary to register with the department of coloproctology and undergo surgical treatment as soon as possible to prevent the abscess from expanding and leading to a systemic infection. The primary surgical treatment for perianal abscesses is a onetime radical surgery, but when there are changes resembling anal fistulas or leakage, options may also include incision, drainage, and seton procedures. After surgery, it is necessary to disinfect the local wound daily and ensure that the wound drainage is unobstructed.
