Laparoscopic surgery has been widely adopted in varieties of benign and malignant gynecologic conditions as it is associated with decreased perioperative complications, enhanced postoperative recovery, shortened hospitalization days and improved incision cosmetic effect. Yet risks of morbidity associated with multiple incisions, including vascular and visceral injury, hernia and infection, pain and other issues still exist. Laparoendoscopic single-site surgery (LESS) may minimize the risks described above and enchance the cosmetic benefits of conventional laparoscopy by performing all the procedures through a small channel in the umbilicus. The safety and feasibility of introducing LESS into endometriosis, especially for treating of ovarian endometrioma, has been confirmed by several studies, while its impact on ovarian reserve still remains controversial, this paper will make a brief summary of these studies.
