目的:探讨经腹超声检查下段食管癌及喷门癌的诊断价值。方法:常规超声经腹探查下段食管喷门部,观察声像图与胃镜和手术结果对照分析。结果:超声对下段食管喷门显示率为93%。正常组厚度约4.1±2.5mm,癌变组约14.5±6.0mm。二者之间存在显著差异P<0.001,以管壁厚度约8.0mm为临界值,超声诊断下段食管癌及喷门癌的灵敏度、准确度分别为96%,95%。对深度和波及范围的判断符合率为75.2%,淋巴结转移的诊断符合率约为80%。结论:超声诊断食管和喷门区癌有独特的优势,能为临床医生做出决策提供更多的信息。
Objective: To investigate the diagnostic value of transabdominal ultrasonography in lower esophageal cancer and squirting cancer. Methods: The conventional ultrasonic abdominal exploration of lower esophageal squirting door to observe the sonogram and gastroscopy and surgical results of controlled analysis. Results: Ultrasound on the lower esophageal spray showed the rate of 93%. The thickness of the normal group is about 4.1 ± 2.5mm, and the cancerous group is about 14.5 ± 6.0mm. There was a significant difference between the two P <0.001, with a wall thickness of about 8.0mm as the critical value, the sensitivity and accuracy of ultrasonic diagnosis of lower esophageal cancer and squirting cancer were 96% and 95%, respectively. The coincidence rate of depth and spread range was 75.2%, and the diagnostic coincidence rate of lymph node metastasis was about 80%. Conclusion: Ultrasound diagnosis of esophageal and squamous cell carcinoma has unique advantages and can provide more information for clinicians to make decisions.
