Abstract
Objective: To determine the value of transvaginal ultrasonography with color Doppler for detecting endometrial polyps in gynecologic examinations.
Methods: We compared the number, size of endometrial polyps, and background of endometrial echogenicity diagnosed before (1 April 2013 to 31 March 2016) and after (1 April 2016 to 31 March 2019) the introduction of color Doppler.
Results: Endometrial polyps were found in 47 of 16,089 patients before, and 286 of 17,182 patients after, the introduction of color Doppler. B mode transvaginal ultrasonography detected 33 endometrial polyps whereas examinations combining B mode and color Doppler detected 253 endometrial polyps. The diameters of endometrial polyps diagnosed with color Doppler were smaller than those diagnosed with B mode. Color Doppler imaging increased the number of cases detected in hyperechoic endometrium where endometrial polyps are not recognized easily by B mode. Before and after the introduction of color Doppler, second-stage tests were performed for 29 and 199 patients, respectively. Among them, the number diagnosed with intracavity pathology, which included other endometrial disease, was 26 before, and 150 after, the introduction of color Doppler.
Conclusion: These results suggested that color Doppler was highly useful for detecting endometrial polyps in gynecologic examinations.
