【摘要】 目的比较常规超声、胃肠水对比超声、双重对比超声造影对壶腹周围癌病灶及其与周围组织关系的显示能力。方法 18例壶腹周围癌病例均经手术或活检证实,所有病例均行常规超声、胃肠水对比超声、双重对比超声造影检查。比较这3种超声检查方法对壶腹周围癌病灶及其与周围组织关系的显示能力。结果常规超声、胃肠水对比超声、双重对比超声造影的病灶清晰显示率分别为16.7%(3/18)、22.2%(4/18)、94.4%(17/18);十二指肠腔内突出物显示率分别为0(0/18)、38.9%(7/18)、72.2%(13/18)。双重对比超声造影对病灶清晰显示率及十二指肠腔内突出物显示率均显著高于前两者(P<0.01,P<0.05)。同时双重对比超声造影显示2例周围血管侵犯和1例肝内转移灶。结论双重对比超声造影可提高壶腹周围癌的显示能力,有望成为诊断壶腹周围癌的一种新方法。更多还原

【Abstract】 Objective To compare the value of conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound in the display capacity of periampullary carcinoma and its relationship with the surrounding tissue. Methods A total of 18 patients with the periampullary carcinoma were diagnosed pathologically or by endoscopic biopsy. Each patient had three imaging modalities by conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound. The display capacity and the relationship between the mass and surrounding tissue were compared with three modalities. Results The display rates of limpid visibilities of carcinoma on conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound were 16.7%(3/18),22.2%(4/18) and 94.4%(17/18),respectively;The display rates of duodenum protrusion on three modalities were 0(0/18),38.9% (7/18) and 72.2% (13/18),respectively,with significant differences among conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound. The double-contrast enhanced ultrasound showed two cases of peripheral vascular invasion and one case of intrahepatic metastasis. Conclusion The double-contrast enhanced ultrasound can increase the display capacity of periampullary carcinoma as a new diagnostic modality for periampullary carcinoma.更多还原
