A prospective study comparing the new sclerotherapy and hemorrhoidectomy in terms of therapeutic outcomes at 4 years after the treatment

Purpose Recently, sclerotherapy using a new sclerosing agent (aluminum potassium sulfate and tannic acid) has become widespread in Japan as a treatment for hemorrhoids. In the present study, we investigated whether sclerotherapy or surgical therapy (hemorrhoidectomy) is superior in terms of the therapeutic outcomes at 4 years.
