The precautions for perianal abscess mainly include those during an acute episode and post-surgical measures. If it is clearly an acute onset of a perianal abscess, it is important to seek treatment promptly. Treatment methods, besides incision and drainage, further include debridement to achieve a complete cure through surgery. Generally, simple incision and drainage only alleviate temporary pain symptoms. If not followed by definitive surgery, there is a high likelihood of developing anal fistulas, necessitating a second surgery. Post-surgical precautions for a perianal abscess primarily involve maintaining cleanliness of the local wound, changing dressings, and ensuring that the drainage from the wound remains unobstructed to prevent false healing.
