It is unclear what the impact is of IUAs on long-term reproductive performance.<\/jats:p>\n <\/jats:sec>\n \n STUDY DESIGN, SIZE, DURATION<\/jats:title>\n This was a follow-up of the PAPA study, a multicenter randomized controlled trial evaluating the application of ACP gel in women undergoing recurrent D&C for miscarriage. All included women received a diagnostic hysteroscopy 8\u201312\u2009weeks after randomization to evaluate the uterine cavity and for adhesiolysis if IUAs were present. Here, we present the reproductive outcomes in women with identified and treated IUAs versus women without IUAs, 46\u2009months after randomization.<\/jats:p>\n <\/jats:sec>\n \n PARTICIPANTS\/MATERIALS, SETTING, METHODS<\/jats:title>\n Between December 2011 and July 2015, 152 women with a first-trimester miscarriage with at least one previous D&C, were randomized for D&C alone or D&C with immediate intrauterine application of ACP gel. Participants were approached at least 30\u2009months after randomization to evaluate reproductive performance, obstetric and neonatal outcomes and cycle characteristics. Additionally, the medical files of all participants were reviewed. Main outcome was ongoing pregnancy. Outcomes of subsequent pregnancies, time to conception and time to live birth were also recorded.<\/jats:p>\n <\/jats:sec>\n \n MAIN RESULTS AND THE ROLE OF CHANCE<\/jats:title>\n In women pursuing a pregnancy, 14\/24 (58%) ongoing pregnancies were recorded in women with identified and treated IUAs versus 80\/89 (90%) ongoing pregnancies in women without IUAs odds ratio (OR) 0.18 (95% CI 0.06 to 0.50, P-value &lt;0.001). Documented live birth was also lower in women with IUAs; 13\/24 (54%) with versus 75\/89 (84%) without IUAs, OR 0.22 (95% CI: 0.08 to-0.59, P-value 0.004). The median time to conception was 7\u2009months in women with identified and treated IUAs versus 5\u2009months in women without IUAs (hazard ratio (HR) 0.84 (95% CI 0.54 to 1.33)) and time to conception leading to a live birth 15\u2009months versus 5.0\u2009months (HR 0.54 (95% CI: 0.30 to 0.97)). In women with identified and treated IUAs, premature deliveries were recorded in 3\/16 (19%) versus 4\/88 (5%) in women without IUAs, P-value 0.01. Complications were recorded in respectively 12\/16 (75%) versus 26\/88 (30%), P-value 0.001. No differences were recorded in mean birth weight between the groups.<\/jats:p>\n <\/jats:sec>\n \n LIMITATIONS, REASONS FOR CAUTION<\/jats:title>\n In the original PAPA study, randomization was applied for ACP gel application. Comparing women with and without IUAs is not in line with the randomization and therefore confounding of the results cannot be excluded. IUAs, if visible during routine hysteroscopy after randomization were removed as part of the study protocol; the influence of IUAs on reproductive outcome may therefore be underestimated. Women undergoing a recurrent D&C for miscarriage were included, a specific group likely to generate clinically significant adhesions. The findings should therefore not be generalized to all women undergoing D&C for miscarriage.<\/jats:p>\n <\/jats:sec>\n \n WIDER IMPLICATIONS OF THE FINDINGS<\/jats:title>\n As IUAs have an impact on reproductive performance, even after hysteroscopic adhesiolysis, primary prevention is essential. Expectative and medical management should therefore be considered as serious alternatives for D&C in women with a miscarriage. In case D&C is necessary, application of ACP gel should be considered.<\/jats:p>\n <\/jats:sec>\n \n STUDY FUNDING\/COMPETING INTEREST(S)<\/jats:title>\n The original PAPA study (NTR 3120) was an investigator initiated study that was funded by the Foundation for scientific investigation in Obstetrics and Gynaecology of the Saint Lucas Andreas Hospital (currently renamed OLVG Oost), SWOGA. The syringes containing ACP gel were received from Anika Therapeutics, the manufacturer of Hyalobarrier\u00ae Gel Endo. The current follow-up study was also an investigator-initiated study without funding. The funder and sponsor had no role in the design of this follow-up study, data collection, data analysis, data interpretation, trial design, patient recruitment, writing of the report or any aspect pertinent to the study. ABH, RAL, JAFH and JWRT have no conflict to declare.
