[The surgical treatment of hemorrhoids].

Surgery is the most effective treatment in patients with symptomatic grade III-IV hemorrhoids who have not responded to outpatient treatment, when there is associated abnormalities (anal fissure, anal fistula, skin tags) and in thrombosed hemorrhoids. Hemorrhoidectomy is currently the "gold standard" treatment. Randomized controlled trials comparing open with closed hemorrhoidectomy show no significant differences in pain scores. Stapled hemorrhoidectomy produces less postoperative pain than hemorrhoidectomy but is less effective in terms of symptom control. No treatment is superior to others in reducing postoperative pain except the use of drugs and anesthetic techniques. In patients with prolapsed internal hemorrhoids and thrombosed hemorrhoids, treatment may initially consist of an urgent hemorrhoidectomy with the same results as those obtained with elective surgery.
