Hemorrhoids.

Understanding of hemorrhoidal pathology and treatment has come a long way. The theory of a sliding anal canal lining and the knowledge that hemorrhoidal cushions are a normal part of the anal anatomy should encourage symptom control rather than radical removal of tissue. Techniques that fix the cushions back in position can be performed in outpatients with reasonable success rates. When required, surgery should be aimed at symptomatic hemorrhoids. It is hoped that new developments such as circular stapling and better pain management will promote increased day surgery, better pain control, and less time off work for patients.
