With the recent development of surgical instruments techniques, minimally invasive surgery is more feasible in various field of surgery. Laparoscopic surgery has potential benefit of decreased patient discomfort, short hospital stay, superior cosmetic results and decreased convalescence time. Recently, various efforts have been continued for minimally invasive surgery, one of the recently emerging concepts is single port surgery. Several studies have demonstrated that single-port laparoscopic surgery is feasible and safe in gynecology.~However, some limits could be occurred, such as the occurrence of less freedom degrees between the instruments and limits surgical vision, thus limiting surgeon's movements. So, two-port laparoscopy combined access through umbilical and additional suprapubic incision have been used and reported. In case of single port access laparoscopic ovarian cyst enucleation, due to limits of surgeon's movements, cyst enucleation or bipolar electrocoagulation of the ovarian parenchyma adversely affected ovarian function.~Some studies reported that after laparoscopic cyst enucleation, there had been shown marked reduction of ovarian function compared with surgery by laparotomy. Therefore we attempt to investigate the impact of single port laparoscopy that have limits of surgical procedures on ovarian reserve after ovarian cyst enucleation.~To evaluate ovarian reserve change, we will use the anti-mullerian hormone. It is produced by granulosa cells of preantral and small antral follicles and has been recently acknowledged as the useful, reliable, and sensitive hormonal serum marker of the ovarian primordial follicle pool. In addition, the AMH level represents a stronger independent marker of ovarian reserve without significant fluctuation during the menstrual cycle, which progressively decreases with age.~Therefore, this prospective study is performed to compare the differences in ovarian reserve after single-port, two-port, or four-port access laparoscopic ovarian cyst enucleation based on serum anti mullerian hormone change. Serum anti mullerian hormone is measured at preoperative and at postoperative 1week, 1 and 3 months.
The purpose of this study is to investigate the impact on ovarian reserve after single- port, two-port, or four-port access laparoscopic ovarian cyst enucleation based on serum anti mullerian hormone change.
