P-93: The Accuracy of Hysteroscopy in Diagnosis of Polyps and Myomas in Patients with Abnormal Vaginal Bleeding

Background Abnormal vaginal bleeding (AUB) is among the most prevalent gynecologic complaints, which is responsible for nearly 33% of all gynecology clinic referees. Intrauterine anatomic lesions are one of the etiologies leading to AUB and hysteroscopy is the gold standard method for evaluating these problems. The accuracy of hysteroscopy vary in different intra-cavitary problems. Gold standard method for diagnosis of myoma or polyp is pathologic examination. The aim of this study was to compare the accuracy of hysteroscopy in diagnosis of myomas and polyps compared to pathologic examination. MaterialsAndMethods Medical records of patients who were undertaken hysteroscopy for AUB were reviewed for the period of 5 years, concerning their sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) in diagnosis of intra-cavitary myoma and polys. Results One hundred and seven women with the mean age of 40.63 ± 10.15 years (ranging from 18 to 70), were assessed. The sensitivity, specificity, PPV, and NPV of hysteroscopic diagnosis for polyps were 94.2, 85.4, 85.9, and 94%, respectively. The sensitivity, specificity, PPV, and NPV of hysteroscopic diagnosis for myomas were 97.7, 88.7, 86.2, and 98.2%, respectively. Conclusion Hysteroscopy is a safe and accurate diagnostic modality. Its sensitivity, specificity, PPV, and NPV of hysteroscopy is higher in diagnosis of uterine mymas compared to polyps.
