Management of an incompetent mid-second (mid-2nd) trimester absent ecto-cervix: a case series. Cervical amplification pre-cerclage insertion

Background Cervical cerclage is a treatment for an incompetent cervix, the latter being a contributor to spontaneous preterm birth.

Description
Summary:Background Cervical cerclage is a treatment for an incompetent cervix, the latter being a contributor to spontaneous preterm birth. There is significant difficulty with a transvaginal cerclage insertion for the absent vaginal or ecto-cervix in the mid-2nd trimester period resulting in a higher risk of late miscarriages, extremely preterm labour with increased neonatal morbidity and mortality. Methods A retrospective review of 5 consecutive cases managed by a surgical technique—modified high vaginal cerclage insertion at 18-20 weeks—and adjunct protocols which included vaginal progesterone use, serial infection screening and lifestyle advice, over a 12-month period ending in August 2021, is presented. Inclusion criteria included minimal or absent ecto-cervix, singleton pregnancies with an incompetent cervix attending for a vaginal cerclage whilst exclusion criteria were the usual contraindications to a cerclage insertion. Primary outcome was delivery after 34 weeks whilst seconday outcomes included maternal hemorrhage, bowel/bladder injury, chorioamnionitis and neonatal admission. Results A increased gestational latency of 13 gestational weeks (range 12–18). Mean gestational age at delivery was 36 weeks +1 (253 days) with a range of 241–264 days. Delivery after 34 weeks gestational age was 100% with no maternal surgical complications and corresponding neonatal outcomes. Conclusion There is a potential therapeutic benefit of this technique and adjunct management, in managing an incompetent mid-2nd trimester absent ecto-cervix.
