Core Tip
Core tip: Medical treatments for acute hemorrhoidal disease come very seldom from randomized, controlled clinical trials. The paper describes that a candidate to a new therapeutic alternative, based on thrombolysis, shows significant efficacy advantage with respect to a widely used, over-the-counter, hemorrhoidal product.
