ABSTRACT

Objective:To investigate the effects of ultrasound-guided intervention with methotrexate combined with lauromacrogol on uterine wall thickness and menstrual recovery time in patients with uterine scar pregnancy.Methods:Sixty patients with uterine scar pregnancy who received treatment in Jinhua Wenrong Hospital, Jinhua Central Hospital, and Yiwu Maternity and Children Hospital from February 2019 to February 2020 were included in this study. They were randomly assigned to receive either uterine artery embolization treatment ( n = 30, control group) or ultrasound-guided interventions with methotrexate combined with lauromacrogol ( n = 30, study group). The success rate of treatment, uterine wall thickness at the scar, menstrual recovery time, hospitalization time, hospitalization expenses, incidence of adverse reactions, serum levels of beta-human chorionic gonadotropin (β-HCG) and high sensitivity C-reactive protein (hs-CRP) after 7 days of treatment and uterine wall thickness before and after treatment were compared between the study and control groups. Results:After treatment, the success rate of treatment in the study group was significantly higher than that in the control group [96.67% (29/30) vs. 70.00% (21/30), χ 2 = 7.680, P < 0.05]. Before treatment, there were no significant differences in β-HCG and hs-CRP levels between the control and study groups ( t = -0.197, 0.197, both P > 0.05). After treatment, serum level of β-HCG in the control and study groups was significantly decreased ( t = 22.803, 10.233, both P < 0.01), and serum level of hs-CRP in the control and study groups was significantly increased ( t = -16.357, 7.854, both P < 0.001) compared with before treatment. After treatment, there were no significant differences in serum β-HCG and hs-CRP levels between the control and study groups ( t = 20.413, -20.306, both P < 0.05). After treatment, the incidence of adverse reactions in the study group was significantly lower than that in the control group [6.67% (2/30) vs. 30.00% (9/30), χ 2 = 5.455, P < 0.05). After treatment, menstrual recovery time, hospitalization time and hospitalization expenses in the study group were shorter or less than those in the control group ( t = 5.080, 5.398, 7.599, all P < 0.05). There was no significant difference in the thickness of uterine wall at the scar site between the two groups ( t = -1.045, P > 0.05). Conclusion:Ultrasound-guided intervention with methotrexate combined with lauromacrogol for treatment of uterine scar pregnancy can effectively increase the success rate of treatment, promote the restoration of menstruation, shorten the length of hospital stay, and is highly safe.
