Adenomyosis among Women undergoing Hysterectomy in the Department of Obstetrics and Gynaecology in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction: Adenomyosis is a gynecological condition that causes endometrial tissue to grow within the uterine myometrium, usually occurs in women in their late reproductive years, often presenting with menorrhagia and dysmenorrhea. There are few studies examining adenomyosis in tertiary care centre in our country. The aim of this study was to find out the prevalence of adenomyosis among women undergoing hysterectomy presenting to the Department of Obstetrics and Gynecology of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted in the Department of Obstetrics and Gynecology of a tertiary care centre, from 13 April 2016 to 14 July 2017, after obtaining ethical approval from the Institutional Review Committee (Reference number: 338/6-11-E-072-73). Women who underwent hysterectomy in the department were included in the study, while those who refused to provide consent were excluded. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 255 women undergoing hysterectomy 85 (33.33%) (27.55-39.12, 95% Confidence Interval) were histologically confirmed to have adenomyosis. The highest prevalence was observed in women aged 41-50 years 59 (69.41%), while the lowest was found in those over 60 years, 2 (2.36%). Adenomyosis was most common among women with a parity of 3 (36.47%). Conclusions: The prevalence of adenomyosis was found to be similar to other studies done in similar settings.
