Abstract

Introduction: Abnormal uterine bleeding in pre and post menopausal period may be
caused by of benign or malignant causes in endometrium or endocervix that need
careful investigations by multiple diagnostic methods such as dilatation and curettage,
diagnostic hysterectomy, endometrial biopsy and tran’s vaginal biopsy.
The aim of this study was to evaluate the diagnostic value of fractional D&C in
assessment of abnormal uterine bleeding.
Methods and Materials: In this descriptive study 156 women between 35 to 70
years old were admitted because of abnormal uterine bleeding after ruling out
pregnancy, hormonal disorder and coagulation disorders. The study was done in 2002
and patients underwent fractional D&C and then hysterectomy because of histological
findings or persistence of symptoms. The results were compared with histological
findings of the hysterectomy specimen (gold standard) and were evaluated for
sensitivity, specificity, positive and negative predictive values of these methods.
Results: In all focal and diffuse uterine disease fractional D&C was 29.5% sensitive
and 88.2% specific and its positive predictive value was 76.5% and its negative
predictive value was 49.2%.
In endometrial pathologies ( such as hyperplasia and …) its sensitivity was 68.4% and
its specificity was 98.3% and positive and negative predictive value were 92.9% and
90.6% respectively. 100% of lyomyoma and adenomyosis cases, 66.6% of
endometrial polyp cases and 2.5% of different endometrial hyperplasia cases were
miss-diagnosed in fractional D&C.
Conclusion: Fractional D&C is not a reliable method for diagnosis of focal uterine
diseases such as myoma or adenomyosis and also endometrial polyps but it is useful
in the diagnosis of endometrial hyperplasia. Based on to the costs of fractional D& C
compared with other diagnostic methods and its pathologic results, routine use of this
method in evaluation of AUB is not recommended.
