Endometrial sampling: a comparison between the Pipelle<sup>®</sup> endometrial sampler and the Endosampler<sup>®</sup>
Keywords:Endometrial sampling, Pipelle endometrial sampler, Endosampler
AbstractObjective: To compare the adequacy of endometrial sampling by the Endosampler® and the Pipelle®. Methods: A total of 68 women were randomly assigned to submit to pre-hysterectomy endometrial sampling, either by the Endosampler® or the Pipelle®. The amount of endometrial tissue sampled was measured by calculating the percentage endometrium sampled by each of the two devices. Acceptance by the gynaecologist was measured on a linear scale. Results: The Endosampler® sampled signficantly more endometrial tissue than the Pipelle® endometrial sampler (p-value = 0.03). Acceptance of the Endosampler® was better than that of the Pipelle® (p-value = 0.0005). With the use of the Pipelle®, three significant endometrial lesions were missed, including endometrial carcinoma in one instance. Conclusion: The Endosampler® appears to be an easy-to-use device for endometrial sampling, with reliable diagnostic yield.
