Hysteroscopic assessment of tubal patency: a prospective randomized comparison between the flow and Parryscope techniques

The primary aim of this study is to evaluate the relalibilty of (1.) the hysteroscopic visualization of a “tubal flow” and (2.) the “Parryscope technique” as compared to the gold standard, namely laparoscopic chromopertubation. The data show that yysteroscopic prediction of Fallopian tube patency was possible in a statistically significant manner in both study groups (p< 0.05). The Parryscope® technique achieved higher sensitivity (90.6%, 95% CI: 61.7-98.4) and specificity (100%, 95% CI: 90.0-100.0) than the flow technique (sensitivity: 73.7%, 95% CI: 48.8-90.9 and specificity: 70.7%, 95% CI: 54.5-83.9).

本研究的主要目的是评估两项检测指标的可靠性：（1）“输卵管液流（tubal flow）”的宫腔镜可视化结果，（2）“Parryscope技术（Parryscope technique）”，并将其与金标准——腹腔镜下亚甲蓝输卵管着色通液术（laparoscopic chromopertubation）进行对比。数据分析显示，两个研究组中，宫腔镜预测输卵管通畅性均具有统计学意义（p<0.05）。Parryscope®技术的灵敏度（90.6%，95%置信区间：61.7-98.4）与特异度（100%，95%置信区间：90.0-100.0）均高于液流法（灵敏度：73.7%，95%置信区间：48.8-90.9；特异度：70.7%，95%置信区间：54.5-83.9）。
