To compare two endometrial sampling devices Medscand Endorette and Pipelle de Cornier with respect to tissue collecting ability, diagnostic accuracy and side effects.
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.
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.
The new Medscand Endorette was preferred due to its higher capacity for collecting adequate samples.
比较两种子宫内膜取样装置——Medscand Endorette和Pipelle de Cornier在组织采集能力、诊断准确性及副作用方面的差异。
对152名有子宫内膜活检医学指征的女性进行一项前瞻性、多中心、交叉研究。在同一时间用两种装置从每位患者身上采集样本，装置使用顺序随机。统计分析基于列联表中的成对比较及McNemars卡方检验。
152名女性中有145名（95%）成功取样。两种装置在不适和出血方面无差异。然而，Medscand Endorette在采集足够样本方面似乎比Pipelle能力更强。当将两种装置作为第一种器械进行比较时，以及在这类检查的主要目标人群（55岁以上女性）中比较结果时，均发现了这种差异。
新型Medscand Endorette因采集足够样本的能力更强而更受青睐。
