Diagnostic value of hysteroscopy in patients with abnormal uterine bleeding

Objective To investigate the diagnostic value of hysteroscopy in patients with abnormal uterine bleeding. Methods The clinical data of 547 cases of abnormal uterine bleeding were analyzed retrospectively.The diagnostic curettage was conducted after hysteroscopy, the specimens were examined by histopathology, the detection result of hysteroscopy and histopathological were compared. Results The sensitivity of hysteroscopy in diagnosed abnormal uterine cavity lesions was 95.83% (161/168), the specificity was 97.63% (370/379), the false positive rate was 2.37% (9/379), the false negative rate was 4.17% (7/168), the positive predictive value was 94.71% (161/170), the negative predictive value was 98.14% (370/377), the Jorden index was 0.934.Hysteroscopy diagnosis showed that the endometrial polyps was 54 cases, the pathological diagnosis coincidence rate was 79.63% (43/54); 93 cases of simple hyperplasia, the pathological diagnosis coincidence rate was 90.32% (84/93); 16 cases of atypical hyperplasia, the pathological diagnosis coincidence rate was 87.50% (14/16); 4 cases of differentiated endometrial adenocarcinoma, the pathological diagnosis coincidence rate was 100.00% (4/4); 2 cases of uterine papillary serous carcinoma, the pathological diagnosis coincidence rate was 100.00% (2/2); 1 case of transitional cell carcinoma of endometrium, the pathological diagnosis coincidence rate was 100.00% (1/1). Conclusion Hysteroscopy can visually observe the morphology of cervical canal and uterine cavity, the diagnostic rate of endometrial polyps, simple hyperplasia, atypical hyperplasia and endometrial carcinoma are higher, so it has important clinical value in the diagnosis of abnormal uterine bleeding.
