[Exploration of post-menopausal uterine bleeding. Hysteroscopy-histology correlation in 94 cases]

Post-menopausal uterine bleeding is the reason for nearly 70% of gynaecological consultations. Because the cause may be a malignant disease, a thorough work-up is necessary to attempt to identify an organic cause.

This retrospective study examined 94 cases of post-menopausal bleeding in which both a hysteroscopic and a histological examination were performed in the gynaecology and obstetrics department of the Hedi Chaker University of Sfax from 1 January 2004 to 28 February 2005. We examined correlations between the hysteroscopy and histology findings as well as the causes determined.

By hysteroscopy, we observed atrophic uterine linings in 53 patients (56%), endometrial polyps in 43 patients (45%), endometrial hyperplasia in 23 patients (24%) and myomas in 24 patients (25.5%). This examination suggested malignancy in 12 patients, among 6 of whom endometrial cancer was confirmed histologically. The sensitivity and specificity of hysteroscopy were relatively poor for the diagnosis of endometrial atrophy (about 48.7% and 68.5%), acceptable for endometrial polyps (75% and 86.6%), endometrial hyperplasia (64.7% and 85.5%), and endometrial cancer (60% and 92.7%).

Hysteroscopy is the most reliable technique for exploration, offering a direct view of the uterine cavity and allowing direct biopsy. Its sensitivity varies according to the indication and diagnosis and is sometimes very good. However, histology remains the reference examination for diagnosis of the cause of post-menopausal uterine bleeding.
