Based on a three-year personal experience with a large number of patients, cryorectal surgery is a reliable and valuable alternative to excision for the removal of all types of hemorrhoids and most other concomitant pathologic conditions found in 44% of these patients. Excellent results should be anticipated, and complications are minimal. No contraindication has yet been detected.
