The objectives were to evaluate if women with symptoms suggestive of endometriosis or adenomyosis but normal ultrasound examination develop endometriosis or adenomyosis lesions visible at ultrasound over time and if alterations of symptoms over time are associated with ultrasound findings at follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>This was a prospective cohort study of 100 symptomatic women with normal initial ultrasound examination during 2014\u20132017 who underwent follow\u2010up ultrasound examination in 2022. Symptoms suggestive of endometriosis were assessed using visual analog scale at both examinations and minimal clinically important difference of 10\u2009mm was considered as a significant alteration. An examiner with expertise in advanced ultrasound examination of endometriosis performed transvaginal ultrasound examinations in accordance with the consensus protocol by the International Deep Endometriosis Analysis group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At follow\u2010up ultrasound examination of 100 women, 13 (13% [95% CI 7.1\u201321.2]) had visible endometriosis or adenomyosis lesions, 8 (8% [95% CI 3.5\u201315.2]) had endometriosis lesions, and 6 (6% [95% CI 2.2\u201312.6]) had adenomyosis. At follow\u2010up, women with endometriosis or adenomyosis lesions reported lower intensity of dysmenorrhea and chronic pelvic pain compared to women without lesions (48\u2009mm [IQR 16\u201379] vs. 73\u2009mm [IQR 46\u201385] and 45\u2009mm [IQR 26\u201357] vs. 57\u2009mm [IQR 36\u201375], <jats:italic>p<\/jats:italic>\u2009=\u20090.087 and <jats:italic>p<\/jats:italic>\u2009=\u20090.026, respectively). None of the women with endometriosis or adenomyosis lesions reported increased intensity of dysmenorrhea at follow\u2010up, compared to 32\/86 women (37%) without lesions (<jats:italic>p<\/jats:italic>\u2009=\u20090.008). Increased intensity of chronic pelvic pain tended to be less common in women with lesions compared to those without (3\/13 [23%] vs. 35\/86 [41%], <jats:italic>p<\/jats:italic>\u2009=\u20090.223).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our findings suggest that in symptomatic women, endometriosis and adenomyosis lesions visible at ultrasound may develop over time. However, majority of women remain having normal ultrasound examinations despite symptoms. Exacerbation of dysmenorrhea or chronic pelvic pain during follow\u2010up was not associated with the development of endometriosis or adenomyosis lesions visible at ultrasound, suggesting that even women with less severe symptoms might benefit from a follow\u2010up ultrasound when indicated.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aogs.14865","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T13:34:00Z","timestamp":1714484040000},"page":"1634-1644","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Evaluating
