Estradiol and intrauterine device treatment for moderate and severe intrauterine adhesions after transcervical resection.

OBJECTIVE

To explore the effect of 4 mg/day, 6 mg/day, and 8 mg/day estradiol alone or in combination with an intrauterine device (IUD) in patients with moderate and severe intrauterine adhesion (IUA) after transcervical resection of adhesion (TCRA).

METHODS

Patients with moderate or severe IUA who reived 4 mg/day, 6 mg/day, and 8 mg/day estradiol alone or in combination with an intrauterine device (IUD) after TCRA in Women's Hospital, Zhejiang University School of Medicine, from March 2014 to December 2014 were enrolled in this retrospective case-control study. In group A, 14 patients received estradiol 4 mg/day + IUD after the first operation; in group B, 29 patients (group B0) received estradiol 6 mg/day after the first operation, and 73 patients (group B1) received estradiol 6 mg/day + IUD; in group C, 14 patients received estradiol 8 mg/day + IUD after the first operation. Referring to ESGE's IUA diagnostic classification method, 72 patients had moderate adhesion, and 58 cases had severe adhesion. Outpatient follow-up was performed at 1 and 23 months and after 1 year. The postoperative menstrual improvement, uterine cavity recovery, drug side effects at two to three months, and pregnancy situation at one year were recorded.

RESULTS

There were no significant differences in age, BMI, and previous intrauterine operation times between the 3 groups (all p > 0.05). Compared with Group A, more patients in group C had severe IUA (p = 0.008). In addition, there were no differences in menstrual recovery, uterine cavity recovery, and pregnancy in one year between the 3 groups (p > 0.05) and between groups B and B (p > 0.05). In group B1, 51 (69.86%) patients had IUD incarceration.

CONCLUSION

This data suggests that 4 mg/d doses of estrogen may have the same effect in improving the menstrual condition, uterine cavity morphology, and reproductive ability compared to a higher dosage (6 mg/day estrogen and 8 mg/day). In addition, the placement of IUD in the uterine cavity during TCRA may cause IUD incarceration, and the treatment results for the prevention of IUA are not better than without IUD.
