Perianal abscesses are localized abscess formations that occur due to repeated infections in the anal crypts. Typically, under perianal ultrasonography, clear pus chambers and related structures can be observed. If perianal abscesses are not treated promptly, there is a high likelihood of expansion of the local pus chambers and dispersion of the pus, leading to an increase in the size of local anal abscesses, which might involve the sacrococcygeal area or the intersphincteric space. The primary treatment for perianal abscesses is surgical, mainly through incision and drainage to evacuate the pus, followed by thorough debridement of the local wound. Additionally, if there are changes in the local sphincter, thread-lifting therapy may also be performed.
