title: Pipelle versus fractional curettage for the endometrial sampling in postmenopausal women.
abstract: The experimental and cross over design study was performed to compare the pain, ability to sample the endometrial issue, and pathological results from pipelle and fractional curettage in post menopausal patients. Thirty naturally menopausal patients who visited King Chulalongkorn Memorial Hospital with abnormal bleeding per vagina from June 1 to December 31, 1997, were enrolled in the study. In group A,endometrial tissue sampling was first conducted by Pipelle and followed by fractional curettage. In group B, the fractional curettage was performed before Pipelle. The results showed that the pain derived by the visual analogue scale of Pipelle and fractional curettage were 3.34 +/- 1.44 (mean +/- SD) and 6.58 +/- 1.75 respectively (p<0.01). The sensitivity and specificity of Pipelle in endometrial tissue samplings compared with fractional curettage were 87.5 and 100 per cent, respectively. One from 3 cases of adeneocarcinoma of the endometrium could not be detected by Pipelle. In conclusion, Pipelle significantly produced less pain than fractional curettage. Even though Pipelle is a simple and easy method for endometrium sampling, the use of Pipelle to replace fractional curettage in the management of postmenopausal bleeding should be done with caution. False negative could occur in the focal disease of malignancy of the endometrium.
