目的探讨胃十二指肠水窗法在壶腹癌超声诊断中的价值。方法63例壶腹癌患者分为常规组35例与水窗组(含饮水前与饮水后)28例,将超声检查结果分为Ⅰ、Ⅱ、Ⅲ级诊断,行常规组与水窗组饮水前后的壶腹癌超声准确率及各级诊断率比较。结果水窗组饮水后壶腹癌的超声诊断准确率96.43%(27/28)与饮水前的60.71%(17/28)及常规组的54.29%(19/35)比较差异均有非常显著性意义,水窗组饮水后Ⅰ、Ⅱ、Ⅲ级超声诊断率与饮水前及常规组比较差异同样有非常显著性意义(均P<0.01),而水窗组饮水前与常规组的超声诊断准确率与Ⅰ、Ⅱ、Ⅲ级超声诊断率比较差异均无显著性意义(均P>0.05)。结论胃十二指肠水窗法为提高壶腹癌超声诊断率的有效方法,有重要的临床价值。
Objective To investigate the value of gastroduodenal water window in the diagnosis of ampulla ultrasound. Methods A total of 63 cases of ampullary carcinoma were divided into routine group (35 cases) and water window group (28 cases before and after drinking water). The results of ultrasonic examination were divided into Ⅰ, Ⅱ and Ⅲ grade. Before and after the ultrasonography of ampulla ultrasound accuracy and diagnostic rates at all levels. Results The diagnostic accuracy of ultrasonography of ampullary carcinoma after water window drinking was 96.43% (27/28) compared with 60.71% (17/28) before water drinking and 54.29% (19/35) in conventional group, all of which were significantly different Significance, water window group after drinking water Ⅰ, Ⅱ, Ⅲ ultrasonic diagnostic rates and drinking water compared with the conventional group also have significant differences (all P <0.01), while water window before drinking water group and the conventional group of ultrasound diagnostic accuracy Rate and Ⅰ, Ⅱ, Ⅲ ultrasound diagnostic rates were no significant difference (all P> 0.05). Conclusion The gastroduodenal water window method is an effective method to improve the diagnostic rate of ultrasonography of ampullary carcinoma and has important clinical value.
