Comparison of the pain scores between tampon, Tao brush and endometrial biopsy as genital tract sampling methods

Tao brush endometrial cytology is a sensitive diagnostic tool for cancer and hyperplasia among women presenting to clinic with abnormal uterine bleeding

“…13,29 Additionally, the monolayer preparation of the collected cells may allow for a more comprehensive assessment of the epithelium. 28,30 Previous studies have suggested the Tao brush method as an attractive alternative to endometrial biopsy as it is just as minimally invasive but less uncomfortable 15,20 and more cost effective. 20 The Tao brush cytology specimen is processed in a very similar manner to cervical cytology, which has been an established diagnostic method for several decades.…”

“…This could spare a large proportion of women with AUB the greater discomfort associated with office endometrial biopsy compared to brushing. 15,16,29 One of the strengths of this study was that each cytology specimen was reviewed by up to three pathologists with routine cytopathology experience but without extensive experience or training in endometrial cytology. This suggests that the learning curve for endometrial cytology may not be a limitation in the further development of endometrial cytology as a diagnostic test.…”

“…12 The technique for Tao brush sampling is simple to learn, and the device appears to sample more endometrial surface area compared to traditional biopsy methods or even the criterion standard for endometrial sampling which is D&C. 13 The sheathed brush design also allows for the sampling of the endometrium while avoiding endocervical contamination 14 and decreasing patient discomfort. 15 , 16 It has been suggested that endometrial samples are more adequately and consistently obtained even from nulliparous and postmenopausal women compared to traditional office endometrial biopsy devices. 13 Additionally, comparable diagnostic sensitivity between Tao brush and endometrial biopsy for EC and atypical hyperplasia (AH) has been demonstrated in studies performed on hysterectomy specimens.…”
