[Ablation of haemorrhoids by cryosurgery in high risk patients (author's transl)].

: A group of 48 patients of differing age and sex, suffering from 3rd degree hemorrhoids with pulmonary, cardiac or renal disease, epilepsy or scleroderma, so that the traditional operation under general anaesthesia is contraindicated, is examined. Cryosurgical haemorrhoidectomy, without hospitalisation, under local anaesthesia of anal sphincter led in all these patients to cure verified rectoscopically 2-3 months after the operation. The postoperative course was entirely normal, with pain symptoms that were sharp in 7 cases, limited in 14. A serohematic secretion occurred for about a week in 6 patients. Normal living and working activity was resumed on average after about 11 days.
