Long abscesses near the anus are commonly found in the following three conditions: first, perianal abscess, which is an infectious disease with a high attack rate around the anus. It is generally due to the infection of the anal sinus, producing inflammation, which reaches the tissue gap through the anal glands and expands the scope of inflammation, manifesting as local redness, swelling, heat and pain, pain is generally distended and relatively intense, and the condition progresses rapidly. Clinically, if the inflammation cannot be controlled, it is recommended that an early surgical incision be made to drain the pus and prevent the infection from continuing to expand. Second, purulent sweat glanditis, often manifested as a ruptured mass around the anus. It is accompanied by intermittent pus flow and painful discomfort and needs to be surgically removed. Third, skin boils, a relatively rare perianal skin disease, local inflammatory infection resulting in painful boils, specific application of antibacterial ointment, if the effect is not good, is also to consider complete surgical excision and debridement.
