To investigate the safety and feasibility of robotic single-site laparoscopy in gynecological surgery.

Clinical data of seven patients undergoing robotic single-site laparoscopic gynecological surgery in the department of obstetrics and gynecology of the First Affiliated Hospital of Air Force Military Medical University from Jan. to Dec. 2018 were retrospectively analyzed to analyze its clinical efficacy. The perioperative data was analyzed as follows: age, BMI, operative time, blood loss, postoperative VAS pain score, time for bowel movement, and hospital stay. Measurement data was presented as mean standard deviation.

All the 7 patients successfully completed the operation, among which 4 patients received robotic single-site laparoscopic surgery with fascia platform and 3 patients with LAGIPORT. Among the patients, 6 cases was diagnosed as endometrial carcinoma which underwent bilateral hysterectomy and pelvic lymph node dissection, and 1 case underwent hysterectomy and DIE dissection for adenomyosis combined with sacral ligament. The median age of the patients was 45 years old (35-57 years old ), the body mass index was 22.9 kg/m² (20.5-25.4 kg/m²), the median operative time was 141 min (115-170 min), the median intraoperative blood loss was 86 ml(50-200 ml), the hemoglobin difference before and after the operation was 6 g/L (5-10 g/L), the median postoperative hospital stay was 5 d(4-6 d), the postoperative intestinal function recovery time was 16.5 h(12-22 h), and the pain score was 1.7 (1-3 points) at 24 h after the operation. Umbilical wound and vaginal stump healed well in all patients after one month.

Robotic single-port laparoscopy can be used safely and effectively in gynecological surgery, but more practical and clinical studies are needed to verify it.
