Two hundred and ninety-five patients with symptomatic haemorrhoids were treated by rubber band ligation as out-patients at St Mark's Hospital, London, between April 1972 and December 1975. Follow-up was possible in 260 patients of whom two-thirds were satisfied with the outcome: 69 patients had residual symptoms for which no treatment had been sought. Nineteen patients eventually required a haemorrhoidectomy.
