RESUMEN
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 ß-human chorionic gonadotropin (ß-hCG) decreased to the nondetectable level within 19-41 days. Menstruation recovery occurred after 10-24 days of normalization of serum ß-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.
