Investigation of the infertile couple: hysteroscopy with endometrial biopsy is the gold standard investigation for abnormal uterine bleeding.
During the last decade hysteroscopy has become the tool of choice for the evaluation of the endometrial cavity, including for assessment of abnormal uterine bleeding (AUB). Many clinicians would consider that, in most patients, the combination of transvaginal sonography and out-patient endometrial biopsy with diagnostic hysteroscopy could replace the need for dilation and curettage. Hysteroscopy was reported to have sensitivity, specificity, negative predictive value and positive predictive value of 94.2, 88.8, 96.3 and 83.1% respectively, in predicting normal or abnormal endometrial histopathology. The highest accuracy of hysteroscopy was in diagnosing endometrial polyps, whereas the worst result was in estimating hyperplasia. Therefore, since the incidence of focal lesions in patients with AUB is high, it seems that the most beneficial approach is to proceed with hysteroscopy complemented by endometrial biopsy early in the assessment of AUB. Nevertheless, the usage of distension media to flush the uterine cavity raises the concern that when the endometrium harbours pathology, there is the potential risk of retrograde dissemination of malignant cells into the peritoneal cavity. The clinical significance of the dissemination of endometrial cells during hysteroscopy is still undetermined.
