Authors compare the results of two groups of patients, with III and IV degree haemorrhoids. The first group (48 patients) were treated with traditional surgery, open or closed. The second group (42 patients) treated with stapling haemorrhoidectomy. The groups were compared in order to determine if a true advantage exists regarding post-operative pain and functional recovery. Authors conclude that stapler haemorrhoidectomy, is somehow better in reducing the pain and offers a quick functional recovery. But the technique must be adopted in selected patients with mucosal prolapse, when the haemorrhoidal plexus is below the dentate line. In those cases, with inveterate mucosal prolapse, and thickened external fibrous tissue, or an irreducible prolapse of the external haemorrhoidal plexus, the choice must be carefully evalutated.
