[Preparation of Cervical Dilatation Before with Misoprostol and Laminaria - Advantages and Disadvantages.] 
The surgical hysteroscopy became popular as a minimally invasive approach to interuterine changes.  Dilatation is a real challenge during surgical hyseroscopy especially in first delivery patients, women in menopause and women with cervical stenosis.  Apart from this, some long hysteroscopy operations such as myomectomy require adequate dilatation in order to facilitate the multiple insertions and drawing pulling of the resectoscope.  Another technical problem is the need for a significant degree of cervical dilatation, as well as softening of the cervix, which will allow the extraction of the excised endometrial polyps or myomatose parts.  Mysoprostol is analogous to prostaglandin El, which is commonly used in obstetrics to induce an abortion and birth, as well as after birth to control the excessive vaginal bleeding.  Its use in gynecology is limited.  In our study it is of vital importance.  The vaginal administration of MysoproStol before surgical hysteroscopy facilitates dilatation.  The eased hysteroscopy minimizes cervical complications.  On the other hand, the natural dilatators Laminaria, made of Laminariajaponica orLaminaria Digitata sticks, are attractive natural substances which can cause dilatation with minimally observed systemic side effects.  They have shown efficient results during the cervical preparation before surgical hysteroscopy.  Despite of that, there are no comparative studies on the efficiency of the two methods for cervical preparation.  The aim of this Study is to compare the efficacy of internally vaginal Mysoprostol against endocervical dilatators Laminaria before surmical hvSterosconv in certain cases.
