Clinical study of hysteroscopic resection for cesarean scar pregnancy

Abstract

Objective To investigate the clinical effect of hysteroscopic scar excision for cesarean scar pregnancy(CSP) and its effect on serum β-human chorionic gonadotropin(β-HCG). Methods From January 2017 to January 2019, 83 patients with endogenous CSP admitted to the People's Hospital of Wenzhou were divided into observation group(43 cases) and control group(40 cases) according to different surgical methods.The observation group underwent hysteroscopic scar lesion resection, while the control group underwent uterine artery embolization.The success rate, intraoperative bleeding volume, vaginal bleeding time and hospitalization time, postoperative complications and the recovery time of blood β-HCG were compared between the two groups. Results The success rate of operation in the observation group was 97.67%(42/43), which was higher than that in the control group[82.50%(33/40)](χ2=3.875, P 0.05). The recovery time of blood β-HCG in the observation group[(19.54±3.52)d]was shorter than that in the control group[(28.73±6.57)d](t=8.020, P<0.05). The total satisfaction rate of the observation group was 97.67%(42/43), which was higher than 77.50%(31/40) of the control group(χ2=6.170, P<0.05). Conclusion Hysteroscopy-assisted scar excision is effective in the treatment of CSP, and can shorten the recovery time of blood β-HCG.
