Internal haemorrhoids: observations on their nature and classification in relation to their management.
Haemorrhoids become manifest as a result of enlargement and downward displacement of collections or cushions of submucosal tissue situated normally in the anal canal. The variation in the size of this tissue and the frequent lack of correlation between size and symptoms make assessment of the various forms of treatment difficult. An objective classification is outlined, together with a rational approach to treatment.
