Open Hemorrohoidectomy Vs Transanal Hemorrhoidal Desarterialization in Hemorrhoids Grade III: The Effect on Symptoms

The goal of this clinical trial is to learn if open hemorroidectomy diminishes symptoms compared to transanal hemorrhoidal desarterialization (THD) in patients presenting with hemorrhoids grade III. The main question it aims to answer is: \- Do patients undergoing open hemorroidectomy present with lesser symptoms 1 year after surgery, compared to those undergoing a THD? Researchers will compare open hemorroidectomy to THD in terms of symptom response one year after the procedure. Participants will: * Undergo surgical treatment of hemorroids performed by one of the two techniques: open hemorroidectomy versus THD. * Fill in symptom forms before and one year after the surgical procedure. * Attend control visits one week, one month, three months and one year after the surgical procedure.
