The Endobrush and Pistolet methods for endometrial cytology sampling are comparable in diagnostic quality and cell yield. Both methods are nearly painless and suitable for clinical use, with Endobrush offering simplicity and speed.

Area of Science:

Gynecologic Pathology
Cytopathology
Women's Health

Background:

Intra-uterine cytological sampling is crucial for diagnosing endometrial conditions.
Comparing the clinical applicability of different sampling devices is essential for optimizing patient care.

Purpose of the Study:

To compare the clinical applicability of the Endobrush and Pistolet intra-uterine cytological sampling methods.
To evaluate cell yield, specimen quality, and diagnostic accuracy of both methods.

Main Methods:

Endobrush and Pistolet sampling methods were used in 113 pre- and postmenopausal women.
Specimens were processed using Papanicolaou staining, with Endobrush samples also prepared as smears.
Cytological evaluations assessed cell number, quality, and diagnostic value.

Main Results:

Specimen collection success rates were 94% for Endobrush and 99% for Pistolet.
Cell yield and quality were comparable between Endobrush filter and Pistolet filter methods.
Endobrush filter method demonstrated diagnostic value similar to the Pistolet method, detecting all four endometrial carcinomas.

Conclusions:

The Endobrush filter method provides cytological endometrial samples comparable to the Pistolet method in cell number, quality, and diagnostic value.
The Endobrush method is simple, quick, painless, and well-accepted by patients, making it suitable for clinical application.
