[Double-balloon catheter compared to vaginal dinoprostone for cervical ripening in obese women at term]

To compare the efficacy of a double-balloon catheter versus vaginal prostaglandin E2 (dinoprostone) for cervical ripening in obese patients with unfavorable cervix at term.The study had an open-label, prospective combined with retrospective, observational design. From January 2013 until May 2016, a prospective cohort study of 46 women with pre-pregnancy BMI30kg/mAfter 24h, there was a significantly higher rate of women with favorable cervix (Bishop score ≥6) in the double-balloon group than in dinoprostone group (80.4% vs 47.8%; P=0.001). After adjustment, a double-balloon catheter was significantly associated with an efficient cervical ripening compared to vaginal dinoprostone (aOR 7.81, 95% CI 2.58-23.60). No difference was observed in cesarean section rate (39.1% in each group; P=0.96) and in mean induction time to vaginal delivery (34.5h in the balloon group vs 36.5h in the dinoprostone group; P=0.53). Maternal and neonatal outcomes were similar.For obese patients at term, cervical ripening using a double-balloon catheter is more efficient on Bishop score after 24h compared to vaginal dinoprostone.
