Brief Summary
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).

Outcome Measures
Primary Outcomes (1)
Ligature-related pain intensity
Patients are asked to record pain intensity related to the hemorrhoidal ligation performed in a chart containing a modified pain intensity visual scale (Wong \& Baker). Investigators inquire patients about immediate pain sensation after a ligation session and at regular intervals, by telephone calls, until the 7th post-treatment day (12 h, 24 h, 2nd day, 3rd day, 4th day, 5th day, 6th day and 7th day).

Study Arms (2)
Single hemorrhoidal ligation
EXPERIMENTALEffective ligation of one hemorrhoidal group and sham ligation of the two other major hemorrhoidal groups is performed in each session of treatment.
Triple hemorrhoidal ligation
EXPERIMENTALThe three major hemorrhoidal groups are ligated in the first session of ligation. The three following monthly appointments of patients of this arm are for sham hemorrhoidal ligations and final revision.
Interventions
Effective ligation of one hemorrhoidal group and sham ligation of the two other major hemorrhoidal groups is performed in each of three sessions of treatment. Final revision is performed 90 days after first session of hemorrhoidal ligation.
The three major hemorrhoidal groups are ligated in the first session of ligation. Sham triple hemorrhoidal ligations are performed 30 and 60 days after the first session. Final revision is done 90 days after first ligation session.
