A multicenter study comparing two endometrial sampling devices--Medscand Endorette and Pipelle de Cornier.
BACKGROUND
To compare two endometrial sampling devices Medscand Endorette and Pipelle de Cornier with respect to tissue collecting ability, diagnostic accuracy and side effects.


METHODS
A prospective, multi-center, cross-over study in 152 women with a medical indication for endometrial biopsy. Samples were collected from each patient on the same occasion with both devices, the order of which was randomized. Statistical analysis was based on pairwise comparison in contingency tables with McNemars chi2 test.


RESULTS
One hundred and forty-five of 152 (95%) women were successfully sampled. There was no difference between the devices concerning discomfort and bleeding. However, Medscand Endorette seemed to have a higher capacity than Pipelle for collecting an adequate sample. This difference was noted when the two devices were compared in the position as first instrument as well as when results were compared in the main target group for this type of examination, for women over 55 years.


CONCLUSIONS
The new Medscand Endorette was preferred due to its higher capacity for collecting adequate samples.
