Abstract
BACKGROUND
Although transvaginal natural orifice transluminal endoscopic surgery (NOTES) is gaining importance, knowledge on transvaginal NOTES procedures in gynecologic practice is limited.
OBJECTIVE
We aimed at evaluating the feasibility and safety of performing hysterectomy and bilateral adnexectomy (or bilateral salpingectomy) via transvaginal NOTES using a self-developed multichannel abdominal port and vaginal support ring.
STUDY DESIGN
A prospective, single-center, cohort pilot study was conducted from May to December 2017 in patients with benign uterine diseases or endometrial atypical hyperplasia or cervical intraepithelial neoplasia (n = 30) scheduled for laparoscopic hysterectomy. The procedure was performed using a self-developed five-channel port and a vaginal support ring.
RESULTS
Hysterectomy and bilateral adnexectomy (or bilateral salpingectomy) in all 30 cases (mean age: 51.43 ± 4.60 years and body mass index: 23.42 ± 1.45 kg/m2 ) were successfully performed completely under transvaginal NOTES. Mean operation time was 95.90 ± 14.60 minutes and mean blood loss during the procedure was 52.50 ± 19.20 mL. Average weight of specimen was 79.97 ± 35.48 g. Only one complication of bladder injury was noted and was rectified accordingly. Visual Analog Score (VAS) at first day after operation was 2.70 ± 0.72. After follow-up for 4.50 ± 1.85 months, all the patients' vaginal stump healed well without scar formation.
CONCLUSION
Our study showed that use of multichannel abdominal port could make laparoscopic instruments easier to fix and operate wherein the vaginal support ring reduces the leakage of carbon dioxide pneumoperitoneum. There was no scar on the abdomen and VAS was much lower. This study also demonstrated cosmetic benefits and rapid postoperative recovery.
