【摘要】 目的 总结分析超声探头加压旋转对于胰头-壶腹周围病变的显示特点,使超声波检查在中老年人筛查病灶方面更加客观、准确。方法 回顾性总结在查体中筛查出90例胰头-壶腹周围病变患者,其中男性69例,女性21例。采用超声探头加压旋转检查手法与不用加压旋转手法比较,根据内部及边缘回声,图像质量,将检查结果与手术、超声造影对比做为金标准。结果 90例病灶中,不用探头加压旋转手法敏感性65.3%,特异性33.3%,准确性60.0%;用探头加压旋转手法敏感性93.0%,特异性81.0%,准确性93.3%。结论 使用超声探头加压旋转法诊断胰腺-壶腹区病变,可明显增强诊断者的信心,但当不用此法又无相应的临床背景资料支持时,筛查的阳性率就相对下降。

【Abstract】 Objective To summarize manifestation features of pressure rotation of ultrasonic probe in screening peripheral lesion of head and ampulla of pancreas,and to find more objective and exact method in screening lesions in middle-aged and elderly people.Methods 90 patients with peripheral lesion of head and ampulla of pancreas screened in medical examination were retrospectively summarized,including 69 males and 21 females.According to a gold standard of result of operation and ultrasonic contrast,interior and limbic echo and image quality by pressure rotation method and by normal examination method were compared and analysed ......
