Application value of hysteroscopy in patients of recurrent spontaneous abortion

Abstract

Objective To evaluate the application value of hysteroscopy in the diagnosis and treatment of recurrent spontaneous abortion patients, and to understand the possible pathogenic factors of recurrent spontaneous abortion. Methods A retrospective study was performed to analyze the findings of 192 cases of recurrent spontaneous abortion, who underwent hysteroscopy examination.According to the number of recurrent spontaneous abortion, they were divided into three groups, group A: 2 times abortion group; group B: 3 times abortion group; group C: >3 times abortion group.Then, intrauterine adhesions detection rate was analyzed. Results Of the 192 cases of recurrent spontaneous abortion, the detective rate of uterine abnormality was 54.7%, the intrauterine adhesion was 34.4%, and in group B and group C, the uterine abnormalities and intrauterine adhesions detection rates (group B: uterine abnormalities 67.1%, intrauterine adhesions detection rate 45.6%; group C: uterine abnormalities 77.8%, intrauterine adhesions detection rate 50.0%) were higher than group A(uterine abnormalities 40.0%, intrauterine adhesions detection rate 22.1%), the differences were significant(χAB2=12.69, χAC2=8.69; χAB2=10.78, χAC2=5.47, all P 0.05). Also found other uterine abnormalities, including uterine malformation 14 cases(7.3%), 12 cases(6.3%) of endometrial polyps, endometritis in 9 cases (4.7%), cervical insufficiency in 2 cases(1.0%), submucous myoma in 1 case (0.5%), pregnancy residues in 1 case(0.5%). Conclusion Hysteroscopy is a noninvasive, intuitive, safe and efficient check.Recurrent spontaneous abortion patients should be routinely performed hysteroscopy, timely detection of pathogenic factors may exist in the uterine and give treatment to improve the pregnancy outcome.
