Description:
<jats:p><b><i>Study Objective:</i></b> Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is a novel minimal invasive surgical technique allowing a variety of gynecological procedures. The current literature describes improved patient comfort, improved better cosmetic results, and reduced operation time. This is a first study to assess pregnancy outcome after fertility-preserving vNOTES procedures. <b><i>Design/Participants/Materials/Setting/Methods:</i></b> We performed a retrospective observational cohort study including 125 patients under 43 years that underwent fertility-preserving vNOTES over a 5-year period (2014–2019). The gynecological surgical procedures included were vNOTES myomectomy, vNOTES salpingectomy for ectopic pregnancy, vNOTES unilateral adnexectomy, and vNOTES cystectomy. A total of 26 pregnancies in 21 cases were observed, with deliveries between 2015 and 2020. <b><i>Results:</i></b> Retrospective analysis in this patient group showed that 18 pregnancies were diagnosed within 1 year after vNOTES (85.7%). Mean interval between surgery and pregnancy was 6 months. Fertility treatment was performed in 28.6%. In the 26 observed pregnancies, no vNOTES-related complications were observed and delivery was at term in all cases. Mode of delivery was a vaginal delivery in twenty cases (76.9% of total) of which 2 cases vacuum assisted (7.7%) and a Caesarean section in 6 cases (23.1% of total). Two cases of trial of labor after Caesarean are described after vNOTES surgery, both ended in an uncomplicated vaginal delivery. In case of vaginal delivery, the perineum was intact in 15%, a mediolateral episiotomy was performed in 50 and 35% a grade 1–2 perineal rupture was described. No grade 3–4 perineal ruptures are described. <b><i>Limitations:</i></b> A limitation of this study is the retrospective design which does not correct for confounding factors. Further larger multicenter studies are needed to validate these data. <b><i>Conclusions:</i></b> This is the first study describing pregnancy outcome after fertility-preserving vNOTES procedures. vNOTES did not affect the mode of delivery or cause pregnancy-related complications. vNOTES did not increase the risk of extensive perineal tears during vaginal delivery. These preliminary data show no adverse events when vNOTES is performed in women of reproductive age. Posterior colpotomy as performed in all vNOTES procedures is by itself not an indication for an elective Caesarean section. </jats:p>
