胰腺占位性病变性质诊断中超声造影的应用及临床价值探讨

Application and Clinical Value of Contrast-enhanced Ultrasonography in the Diagnosis of Pancreatic Space Occupying Lesions

目的:探讨胰腺占位性病变性质诊断中超声造影的应用及临床价值。方法:选取2017年4月-2018年12月本院收治的疑似胰腺占位性病变患者55例作为研究对象。分析胰腺实质、良性、恶性病变超声造影检查时的相变化,胰腺良性、恶性病变超声造影检查时的相变化,胰腺良性、恶性病变造影增强检查时的表现,超声造影、常规超声诊断胰腺病变最终结果。结果:恶性病变始增时间长于良性病变与胰腺实质(P<0.05);恶性病变始减时间、渡越时间均短于良性病变与胰腺实质(P<0.05);良性病变与胰腺实质始增时间、始减时间及渡越时间比较,差异均无统计意义(P>0.05)。良性病变与恶性病变晚增同退、无增、早增晚退相比,差异均无统计学意义(P>0.05),良性病变晚增早退、同增早退少于恶性病变,同增同退多于恶性病变,差异均有统计学意义(P<0.05)。良性病变部分增强、全部增强与恶性病变相比,差异均有统计学意义(P<0.05)。超声造影诊断正确率高于常规超声,不能定性率低于常规超声,差异均有统计学意义(P<0.05);两者诊断错误率相比,差异无统计学意义(P>0.05)。结论:胰腺占位性病变性质诊断中,超声造影可以对血流灌注情况进行观察,可为临床诊断、鉴别胰腺占位性病变提供一定的参考价值,临床利用价值较高。

Objective:To explore the application and clinical value of contrast-enhanced ultrasound in the diagnosis of pancreatic space occupying lesions.Method:From April 2017 to December 2018,55 patients with suspected pancreatic space occupying lesions admitted to our hospital were selected as the research objects.The pancreatic parenchymal,benign,and malignant lesions during ultrasound contrast examination,pancreatic benign and malignant lesions during ultrasound contrast examination,pancreatic benign,malignant lesions during contrast enhancement examination,Ultrasound contrast,conventional ultrasound diagnosis of pancreatic lesions the final result were analyzed.Result:The initial increase time of malignant lesions was longer than those of benign lesions and pancreatic parenchyma (P<0.05);the initial decrease time and transit time of malignant lesions were shorter than those of benign lesions and pancreatic parenchyma (P<0.05);the initial increase time,the initial decrease time and the transit time between benign lesions and pancreatic parenchyma were not statistically significant (P>0.05).There were no significant differences in late increase and regression,no increase,early increase and late regression between benign lesions and malignant lesions (P>0.05);the increase and decrease were less than those of malignant lesions (P<0.05);the same increase and decrease were more than those of malignant lesions (P<0.05).The partial enhancement and full enhancement of benign lesions and malignant lesions compared,the differences were statistically significant (P<0.05).The diagnostic accuracy of contrast-enhanced ultrasound was higher than that of conventional ultrasound,the undetermined rate was lower than that of conventional ultrasound (P<0.05);there was no significant difference in the diagnostic error rate between two groups (P>0.05).Conclusion:In the diagnosis of the nature of pancreatic space occupying lesions,contrast-enhanced ultrasound can clarify the clear blood perfusion and provide a certain reference value for clinical diagnosis and identification of pancreatic space occupying lesions.and the clinical value is higher.
