超声诊断非壶腹部十二指肠肿瘤

Diagnosis of non-ampulla of Vater duodenal tumor with ultrasonography

目的:探讨常规腹部超声及饮水后声像图在非壶腹部十二指肠肿瘤诊断中的价值。方法:回顾性分析了14例非壶腹部十二指肠肿瘤的声像图表现。结果:超声检查14例均表现为胰头附近的低回声肿块,13例超声诊断为十二指肠肿瘤,1例诊断为腹膜后肿大淋巴结。14例中,13例经手术病理证实为十二指肠肿瘤,1例经十二指肠镜诊断为十二指肠炎。通过常规腹部超声及饮水后超声检查,12例十二指肠肿瘤获得了正确的观察定位诊断,超声诊断正确率为85.7%(12/14)。结论:通过对特异的位置及形态特征的观察,超声可对多数的十二指肠肿瘤做出正确的定位及定性诊断,饮水后声像图对其诊断有一定的帮助作用。

Objective：To study the value of conventional abdominal sonography and sonography after oral water ingestion in the diagnosis of non-Vaterian duodenal tumor. Methods： The sonography of 14 patients with non-Vaterian duodenal tumor was studied retrospectively. Results：All the 14 cases showed hypoechoic masses at the right of pancreas head or inferior to pancreas head. Thirteen cases were diagnosed as duodenal tumor by ultrasonography, another one was diagnosed as enlarged lymphnode. Of all the 14 cases, 13 cases were duodenal tumor demonstrated by the surgical and histological examination, one ease was diagnosed as duodenifis by duodenoscopy. Twelve of all the 14 cases were diagnosed correctively by conventional abdominal sonography and sonography after oral water ingestion. The corrective rate was 85.7%. Conclusion：Because of the special location and shape, most duodenal tumor can be diagnosed correctively by conventional abdominal sonography. The sonographic examination after oral water ingestion is hdpful to the diagnosis of duodenal tumor.
