Comparison of Endometrial Pathology between Tissues Obtained from Manual Vacuum Aspiration and Sharp Metal Curettage in Women with Abnormal Uterine Bleeding.

OBJECTIVE

To study the correlation of endometrial pathology, which were derived from manual vacuum aspiration (MVA) and sharp metal curettage (SMC).

MATERIAL AND METHOD

Women aged over 35 years old who presented with abnormal uterine bleeding were enrolled. Endometrial biopsy using MVA and sharp metal curettage under paracervical nerve block were performed, respectively. Correlation of endometrial pathology from both methods and correlation between endometrial pathology from MVA and the most severe pathology were analyzed using Kappa statistics.

RESULTS

One hundred and thirty two women were enrolled Nine cases were drop out because of inability to pass the MVA's cannula through the cervical os. Mean age was 49.3 ± 8.5 years old. Mean BMI was 25.1 ± 4 kg/m². Pathological correspondence between tissue obtained from MVA and sharp metal curette was 64.2% and the Kappa agreement was 0.56 (K0 = 0.56, p-value < 0.05). Pathological correspondence between tissue obtained from MVA and the most severe pathology was 92.7% and the Kappa.agreement was 0.86 (K = 0.86, p-value < 0.05). MVA could diagnose all cases of malignancy and endometrial hyperplasia.

CONCLUSION

Manual vacuum aspiration (MVA) can be used as an alternative diagnostic procedure in women with abnormal uterine bleeding.
