Prevalence of endometriosis among patients with adenomyosis and/or myoma uteri scheduled for a hysterectomy.

OBJECTIVE

To estimate the prevalence of endometriosis among patients between 40 and 50-years-old that required a hysterectomy with an indication of adenomyosis and/or myoma uteri.

MATERIAL AND METHOD

This cross-sectional study was conducted in a university hospital. Two hundred twenty consecutive premenopausal women, aged 40 to 50-years-old, with symptomatic adenomyosis and/or myoma uteri, and scheduled for a total abdominal hysterectomy were enrolled. During laparotomy, a systematic inspection of the pelvis was carried out to identify endometriosis.

RESULTS

The presence of endometriosis was observed in 63 (28.6%) of 220 patients. The prevalence of endometriosis was 19 in 47 (40.4%) patients with adenomyosis, 30 in 132 (22.7%) patients with leiomyomas, and 14 in 41 (34.1%) patients with adenomyosis and leiomyomas. The rate of coexistence of endometriosis in the women with adenomyosis was statistically significantly higher than in the patients with leiomyomas (p-value = 0.032). Younger age, moderate-severe pain, and short menstrual interval were shown to be independent risk factors for endometriosis among these patients.

CONCLUSION

The prevalence of endometriosis in the women with adenomyosis was higher than in those with leiomyomas.
