Does repetitive dilatation and curettage or hysteroscopic biopsy in patients treated with progestins for endometrial hyperplasia or carcinoma affect subsequent fetomaternal outcomes? A population‐based study using the National Health Insurance Research Database of Taiwan

Objective To investigate the impact of repeated dilatation and curettage or hysteroscopic biopsy on fetomaternal outcomes in patients receiving progestin treatment for endometrial hyperplasia or early‐stage carcinoma. Method This was a population‐based study using the Taiwan National Health Insurance Research Database between 2009 and 2017 of women who gave birth and had a history of endometrial hyperplasia and early‐stage carcinoma treated with progestins. Logistic regression analysis was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs) reflecting the association between repeated procedures and fetomaternal outcomes. Results A total of 6956 women with 8690 deliveries were identified. Compared with those who had two or fewer procedures, women who received more than two procedures had a significantly higher risk for cervical insufficiency (aOR, 5.09 [95 CI, 2.31–11.24]). Furthermore, women who had more than two procedures were prone to have adverse neonatal outcomes, including Apgar score
