Abstract:Objective To compare the clinical efficacy of estradiol gel and estradiol valerate tablets in patients with moderate and severe intrauterine adhesions (IUA) after transcervical resection of adhesion (TCRA), and explore the application value of estradiol gel after electrotomy of IUA.Methods Clinical data of 213 patients with moderate-severe intrauterine adhesions who underwent TCRA from January 2018 to January 2020 were retrospectively analyzed, patients were divided into percutaneous group (n = 109) and oral group (n = 104) according to different postoperative drug dosage forms and administration routes. The concentration of estradiol in peripheral blood, endometrial thickness, American Fertility Society (AFS) score and improvement of menstrual volume were compared between the two groups after treatment.Results Compared with the oral administration group, the intimal thickness of the percutaneous administration group was significantly increased, and the AFS score was significantly decreased, with statistically significant differences (P < 0.05). There was no significant difference in peripheral blood estradiol concentration, menstrual flow, pregnancy rate, miscarriage rate, coagulation function and liver and kidney function between the two groups (P > 0.05).Conclusion The use of percutaneous estradiol gel after TCRA of moderate-severe intrauterine adhesions can significantly increase intimal thickness and reduce AFS score.
