Comparative analysis of the clinical efficacy and reproductive outcomes of the hysteroscopic tissue removal system (MyoSure) and hysteroscopic electroresection in the treatment of benign intrauterine lesions.

Abstract

To compare and analyze the clinical efficacy and reproductive outcomes of the hysteroscopic tissue removal system (MyoSure) and hysteroscopic electroresection in the treatment of benign intrauterine lesions in women of reproductive age. This is a retrospective study of patients with benign intrauterine lesions treated with MyoSure or hysteroscopic electroresection. The primary outcomes were operative time and resection completeness, and reproductive outcomes were followed up and compared. Secondary outcomes included perioperative adverse events and postoperative adhesions seen during second-look hysteroscopy. Data analysis was performed using χ2 and Fisher tests for qualitative variables and Student t-test for quantitative variables. The operative times of patients with type 0 or I myoma, endometrial polyps, or retained products of conception in the MyoSure group were shorter than those in the electroresection group but were not significantly different for patients with type II myomas. The complete resection rate was lower in the MyoSure group than in the electroresection group. The degree of decrease in the American Fertility Society score of intrauterine adhesion in the MyoSure group was significantly higher (2.90 ± 1.29 points vs 1.31 ± 0.89 points, P = 0.025). The time to pregnancy and the pregnancy rate were higher in the MyoSure group (13.14 ± 7.85 months vs 16.26 ± 8.22 months, P = 0.040; 65.12% vs 54.55%, P = 0.045), but there was no significant difference in the term live birth rate, premature birth rate, or abortion rate between the two groups. MyoSure has advantages of a shortened operative time and improvement in reproductive outcomes such as pregnancy rate. However, for type II myomas, MyoSure has limitations, and a comprehensive evaluation before the procedure is required.
