The introduction of hysteroscopy in clinical practice changed significantly our knowledge of uterine cavity, but did not stimulate the start of big studies with aim to evaluate the feasibility of conservative treatments for better defined diseases as endometrial polyp. The use of curettage(D&C) has led the gynecologists to consider diffuse atypical endometrial hyperplasia and atypical polyp as the same disease. The treatment of these precancerous lesions recommended by scientific societies is aggressive (hysterectomy). Surprisingly, regarding hysterectomy we did not observe management modifications after the introduction of endoscopic techniques, as happened in other surgical disciplines.
