腹部彩超检查在肿块型胰腺炎和胰腺癌诊断中的价值分析

The Value of Abdominal Color Ultrasonography in the Diagnosis of Mass Pancreatitis and Pancreatic Cancer

目的探讨腹部彩超检查在肿块型胰腺炎与胰腺癌诊断中的临床价值。方法回顾性分析2014年1月至2018年6月本院收治的57例肿块型胰腺炎患者及58例胰腺癌患者的腹部彩超检查结果,从临近血管变化、胆总管阻塞形态、肿块内部血流、肿块边缘、肿块形态等方面比较两组声像图的差异。结果肿块型胰腺炎与胰腺癌的超声表现:病灶位置[胰头部(71.93%vs.68.97%)]、肿块形态[形态不规则(71.93%vs.68.97%)]、点棒状血流信号(7.02%vs.8.62%)、病灶后方回声增强(54.39%vs.6.90%)、邻近血管变化(77.19%vs.84.48%)、内部不均质(82.46%vs.96.55%)、病灶内强回声斑块(49.12%vs.0)、腹腔淋巴结肿大(7.02%vs.46.55%)、低回声(73.68%vs.79.31%);经χ2检验,肿块型胰腺炎在病灶内强回声斑块、病灶后方回声增强表现明显强于胰腺癌,P<0.05;胰腺癌在内部不均质、腹腔淋巴结肿大表现明显强于肿块型胰腺炎,P<0.05;而肿块型胰腺炎与胰腺癌在病灶位置、肿块形态、点棒状血流信号、邻近血管变化、低回声等表现方面比较,无显著性差异(P>0.05)。结论肿块型胰腺炎与胰腺癌在超声声像图上具有比较显著的差异,可通过腹部彩超进行鉴别。

Objective To explore the clinical value of abdominal color ultrasonography in the diagnosis of mass pancreatitis and pancreatic cancer.Methods From January 2014 to June 2018,57 patients with mass pancreatitis and 58 patients with pancreatic cancer in our hospital were analyzed retrospectively.The differences between the two groups were compared in terms of the changes of adjacent blood vessels,the morphology of common bile duct obstruction,the internal blood flow of the mass,the edge of the mass and the shape of the mass.Results The ultrasonic manifestations of mass pancreatitis and pancreatic cancer were as follows:the location of the focus(71.93%vs.68.97%),the shape of the mass(71.93%vs.68.97%),the point bar blood flow signal(7.02%vs.8.62%),the echo enhancement behind the focus(54.39%vs.6.90%),the change of adjacent vessels(77.19%vs.84.48%),the internal heterogeneity(82.46%vs.96.55%),hyperechoic plaque(49.12%vs.0),abdominal lymphadenopathy(7.02%vs.46.55%),and hypoechoic(73.68%vs.79.31%)in the lesion;the disease The results showed that the intensity of echo plaque in the focus and the echo enhancement in the back of the focus were significantly higher than those in the pancreatic cancer,P<0.05,and the heterogeneity of the inner part and the enlargement of the abdominal lymph nodes were significantly higher than those in the mass pancreatitis(P<0.05).Compared with pancreatic cancer,the mass pancreatitis showed the location of the focus,the shape of the mass,the blood flow signal of the point bar,the changes of the adjacent blood vessels and the low echo,P>0.05.Conclusion There is a significant difference between mass pancreatitis and pancreatic cancer on ultrasonography,which can be differentiated by abdominal color ultrasound.
