    Abstract:
    OBJECTIVE: To describe the feasibility of hysteroscopy-assisted suction curettage for early pregnancy loss and to investigate whether it reduces the rates of retained products of conception (RPOC) and intrauterine adhesions (IUA). DESIGN: Prospective single-arm cohort study. SETTING: University-affiliated Department of Obstetrics and Gynecology. PATIENTS: Women admitted for surgical evacuation of early pregnancy loss were invited to participate in the study. INTERVENTION: Vaginal misoprostol was administered for cervical ripening preoperatively. Under general anesthesia, a diagnostic hysteroscopy was performed to identify the pregnancy's implantation wall, followed by ultrasound-guided suction and curettage directed to the implantation wall, and then diagnostic hysteroscopy to verify complete uterine cavity emptying. Postoperative IUA were evaluated by follow-up office hysteroscopy. MAIN OUTCOME MEASURE: Identification of the pregnancy's implantation wall on hysteroscopy, and intra-, and postoperative complications associated with the procedure. The evaluation of postoperative IUA was limited due to the COVID-19 pandemic-related restrictions on elective procedures. RESULTS: Forty patients were included in the study group. Their mean age was 34.0 ± 6.6 years, and their mean gestational age was 8.9 ± 1.6 weeks. The implantation wall was clearly visualized on hysteroscopy in 33 out of 40 cases (82.5%). The mean operative time was 17.2 ± 8.8 min, and no intraoperative complications occurred. Suspected RPOC were diagnosed intraoperatively by hysteroscopy and removed in 4 cases, and the histologic examination confirmed the presence of RPOC in three of them. Follow-up office hysteroscopy was performed in nine women: mild IUA was diagnosed in one case and a normal cavity was confirmed in eight cases. A new pregnancy was reported at the time of follow-up in 15 cases, while 12 women declined to attend the follow-up hysteroscopy and four were lost to follow-up. CONCLUSIONS: Hysteroscopy-assisted suction curettage for early pregnancy loss is a safe, short, and inexpensive procedure, which allows the identification of the pregnancy's wall in most cases and may reduce the rates of RPOC.
