Supplementary Material for: Evaluation of the Efficacy of Ultrasound-Guided Local Lauromacrogol Injection Combined with Aspiration for Cesarean Scar Pregnancy: A Novel Treatment

Objectives: To evaluate the efficacy of ultrasound-guided local lauromacrogol injection combined with aspiration for treating cesarean scar pregnancy (CSP). Methods: From July 2016 to December 2016, 18 patients diagnosed with CSP were treated with ultrasound-guided local lauromacrogol injection combined with aspiration. Clinical data and outcome were analysed. Results: All patients were treated successfully. The amount of bleeding ranged between 10 and 50 mL. The duration of hospitalization ranged between 2 and 11 days. Serum β-human chorionic gonadotropin (β-hCG) decreased to the nondetectable level within 19–41 days. Menstruation recovery occurred after 10–24 days of normalization of serum β-hCG level. Reproductive functions were preserved, and there were no untoward effects or complications. Conclusions: Ultrasound-guided local lauromacrogol injection combined with aspiration is an effective CSP therapy, as it was associated with a high success rate, short hospitalization and fast recovery. However, its wider application and popularization have to be validated on a larger patient population affected by CSP.
