目的探讨彩色超声对壶腹癌的诊断价值。方法对经彩色超声检查的88例壶腹癌与手术病理进行对照分析。结果超声诊断符合率88.63%(78/88),胆道梗阻部位定位诊断符合率100%(88/88)。本组患者声像图分为2类:肿块型和缩窄截断型;肿块内检出斑点状、条状、短棒状血流信号32例,缩窄截断型无一例检出血流信号。结论壶腹癌具有较典型的超声特征,彩色超声诊断壶腹癌直观、快捷,对临床治疗手段的选择意义重大,是壶腹癌首选影像学诊断方法。
Objective To investigate the diagnostic value of color ultrasound in ampullary carcinoma. Methods Eighty-eight cases of ampullary carcinoma and pathology were examined by color sonography. Results The coincidence rate of ultrasonic diagnosis was 88.63% (78/88), and the coincidence rate of biliary tract obstruction diagnosis was 100% (88/88). The group of patients with sonographic images divided into two categories: mass-type and narrowed truncated type; detected within the mass spotted, strip, short rod-shaped blood flow signal in 32 cases, no case of narrowed truncated blood flow signal detection. Conclusion The diagnosis of ampullary carcinoma is more typical. Ultrasonography is an intuitive and rapid diagnostic method for ampulla of carcinoma of the ampulla, which is of great significance to the choice of clinical treatment. It is the imaging diagnostic method of choice for ampullary carcinoma.
