Study Arms:
- Polidocanol foam sclerotherapy (Type: EXPERIMENTAL): 1. Preparation of the polidocanol foam according to Tessari technique immediately before application (so that the microbubbles of the foam did not disintegrate);~2. Application according to the Blanchard technique (Fig. 2) through a disposable transparent anoscope, with the patient in jackknife position, using a 20mL disposable syringe of the mixture (polidocanol + air) and a reusable 10 cm syringe extender adapted to an intravenous needle;~3. Patients treated in a maximum of 3 sessions at 3 weeks intervals;~4. Maximum dose per treatment session of 20mL of mixture of 4mL of polidocanol 3% with 16mL of air;~5. In each session more than one hemorrhoid cushion could be treated.
- Rubber band ligation (Type: EXPERIMENTAL): 1. Use of reusable metal ligation device connected to a vacuum system (McGown suction method) to apply the rubber bands above the dentated line through a disposable transparent anoscope with the patient in jackknife position;~2. A maximum of 3 sessions of ligation at 3-week intervals were performed;~3. More than 1 band per session could be applied.

Based on this trial design, predict the completion outcome and termination type (if applicable).
