Rubber band ligation is a widely adopted treatment of internal hemorrhoids in busy coloproctology institutions. All three major hemorrhoidal clusters (left lateral, right anterior and right posterior) use to be ligated in order to obtain therapeutic success. It is commonly performed either through the ligation of a single hemorrhoid per session spaced by some few weeks to the second and third sessions, or of all three major hemorrhoids in one single session. Advocates of either method of hemorrhoidal ligation have arguments to defend their choice in terms of advantages, supported mainly on personal preferences. The investigators objective is to determine, through a controlled double-blinded randomized study, if there is any superiority of single hemorrhoidal ligation per session (in a total of three sessions) over the method of ligation of all three main hemorrhoids in a sole session in terms of therapeutic success (resolution of pre-ligation symptoms), morbidity, patient satisfaction and costs (institutional, labor and patient-related).
