To compare the clinical performance of two endometrial sampling devices, the GynoSampler and Pipelle.
During a single office visit, gynecology patients at Women's Hospital, Los Angeles, and the teaching clinic of the University of Florida Health Science Center, Jacksonville, underwent two endometrial biopsies, one with each device. The specimen adequacy, pain associated with the sampling procedure and ease of use of the two devices were compared.
One hundred women, 50 at each clinical center, were evaluated. No significant differences in specimen adequacy were noted, with at least 90% of specimens retrieved with each device sufficient for diagnosis. Patient discomfort ratings were similar for the two devices. However, physicians performing the biopsies noted that the GynoSampler device was easier to use than the Pipelle based on three parameters (P < .05).
Although the GynoSampler and Pipelle appear comparable from the perspectives of diagnostic performance and patient discomfort, the GynoSampler was easier to use.
