1. Must be operated immediately
1. Perianal abscess, pus has formed, and the whole body may be feverish (if there is no emergency operation, the abscess spreads in mild cases, the scope increases, and the redness, heat and pain are aggravated; in severe cases, sepsis enters the blood, shock may occur and life threatening);
2. Rectal prolapse and incarceration pain (if there is no emergency surgery, it can cause prolapse and necrosis of intestinal edema);
3. Pain in incarcerated internal hemorrhoids (if emergency surgery is not performed, it may cause edema and necrosis of incarcerated internal hemorrhoids);
4. Thrombotic external hemorrhoids (if emergency surgery is not performed, it can cause severe pain and bleeding after skin breakage);
5. Necrotizing fasciitis (low incidence, but high mortality).
2. Elective Surgery (Surgery is recommended, but the time of surgery can be selected)
1. Stage II and III hemorrhoids (prolapse of anal mass or blood in the stool often occurs);
②Old anal fissure (periodical bowel pain);
③Anal fistula (recurrent pus next to the anus);
④Anal papilloma or anal papillary hypertrophy (generally physical examination found that the symptoms are few, and severe cases have prolapsed mass and blood in the stool);
