Usefulness of saline infusion sonohysterography and feeding artery imaging in endometrial polyp diagnosis
Abstract
Objectives: The aim of this study was to assess the usefulness of sonohysterography with feeding artery visualization using transvaginal sonography to diagnose endometrial polyps.
Material and methods: We conducted an observational study of 60 perimenopausal patients referred to the Department of Fetal Medicine and Gynaecology, Medical University of Lodz with abnormal uterine bleeding or suspicion of endometrial pathology based on sonography scan. In all 60 patients transvaginal sonography scan showed a possibility of an endometrial polyp. Of these, 46 underwent saline infusion sonohysterography with sonography visualization of a feeding artery. Pathological examination was performed on material collected during hysteroscopy.
Results: Sonography detection of endometrial polyp based on feeding artery visualization had a 40% sensitivity, whereas sonohysterographic polyp detection had a sensitivity of 75% and a specificity of 100%. The positive and negative predictive values of saline infusion sonohysterography in diagnosing endometrial polyps were estimated at 75% and 72% (95% CI: 52–86%), respectively. The combination of sonohysterography and feeding artery imaging in transvaginal sonography was 84% sensitive and 95% specific in detecting endometrial polyps. The positive and negative predictive values were: PPV = 96% and NPV = 89%.
Conclusion: Saline infusion sonohysterography with feeding artery visualization may become a standard method in the diagnostics of endometrial polyps in perimenopausal women.
