The perineal approach generally results in less post-operative pain and complications, and a reduced length of hospital stay. These procedures generally carry a higher recurrence rate and poorer functional outcome. The perineal procedures include perineal rectosigmoidectomy and Delorme repair. Elderly, or other medically high-risk patients are usually treated by perineal procedures, as they can be performed under a regional anesthetic, or even local anesthetic with intravenous sedation, thus avoid the risks of a general anesthetic. Alternatively, perineal procedures may be selected to reduce risk of nerve damage, for example in young male patients for whom sexual dysfunction may be a major concern.
