As one type of the laparoscopic surgery, the laparoendoscopic single-site (LESS) surgery has been developed in an attempt to further reduce the morbidity and scarring associated with surgical intervention [1, 2]. Single-site Gynecologic Surgery is widely carried out all over the world during the recent years. More and more gynecological endoscopic surgeries use this single-site technology, especially transumbilical single-port. In china, the number of LESS has increased dramatically from 2017. Our hospital started to carry on this technology from September 2017. Many researches have indicated advantages of it, such as less postoperative pain and quick recovery, less skin scar etc. Some results are conflicting [3, 4, 5, 6, 7, 8, 9, 10]. The advantages of LESS are still uncertain.

Current Situation in our Hospital

From November 2017 to November 2018,105 LESS gynecological surgeries were performed, 35 ovarian cystectomies, 38 unilateral fallopian tube resections, 22 myomectomies and 10 hysterectomies through LESS. Only one surgery needed one more additional port. No patients have severe complications. Operative time, intraoperative blood loss and perioperative complications have no difference, compared with the conventional laparoscopy. The LESS laparoscopy group had less postoperative pain scores and longer bowel recovering time, compared with the conventional laparoscopy (Table 1).

Laparoendoscopic single site surgery(LESS)is a single port technique through the umbilicus, in the past 10 years, LESS has emerged as a potentially less invasive alternative to multiport laparoscopy.

At the beginning, a homemade single port is easier to get, low cost and has a good socioeconomic performance. YH Park was the first person who reported that he uses a homemade single port device to perform laparoendoscopic single-site nephrectomy [11]. Many countryside hospitals in china used this kind of homemade single port.

In the application of any new technique, the safety of the patients is always the most important. After a median follow-up period of 3 months, there is no complaint of the LESS surgery. All the LESS group patients were fully satisfied with the appearance of the incisions. We think all surgeons could complete LESS after the learning curve.

In this study, all the patients are benign. Most of patients care about the appearance of the incisions, especially the young patients. Now in our department, many patients are willing to take LESS. Some Chinese doctor applied LESS to malignant diseases, such as cervical cancer, early Ovarian Cancer and endometrial carcinoma [12, 13, 14].

We think that the future thread would be single-site robotic surgery associated AI technology.


LESS surgery is less invasive, suitable and safe for gynecological surgery. It has been widely promoted in China.
