逆行保留灌肠法联合实时超声造影诊断结肠病变的临床价值

Value of Retrograde Retention Enema Combined with Real Time Contrast-enhanced Ultrasonography in the Diagnosis of Colonic Lesions

目的探讨逆行保留灌肠法联合实时超声造影诊断结肠病变的临床价值。方法选取2013年10月至2015年2月东莞市清溪医院收治的50例结肠病变患者作为研究对象,28例为恶性病灶组,22例为良性病灶组。选择同期健康检查无结肠病变的体检者30例作为对照组。所有受检对象均行逆行保留灌肠法联合实时超声造影检查,比较3组受检对象定量参数到达时间、达峰时间、上升时间、基础强度、峰值强度及强度相对值。结果恶性病灶组受检对象峰值强度、强度相对值均明显高于对照组以及良性病灶组,到达时间、达峰时间均明显短于对照组以及良性病灶组,差异均有统计学意义(均P<0.05);同时,良性病灶组受检对象峰值强度、强度相对值均明显高于对照组,到达时间、达峰时间均明显短于对照组,差异均有统计学意义(均P<0.05)。结论逆行保留灌肠法联合实时超声造影能够准确区别正常结肠组织与病变组织,同时可对病灶良恶性作出较可靠鉴别,在结肠病变的临床诊断中具有重要价值。

Objective To explore the value of retrograde retention enema combined with real time contrastenhanced ultrasonography in the diagnosis of colonic lesions.Methods In October 2013 to 2015 February Dongguan City Cheonggye hospital treated 50 cases of colonic lesions were selected as the research object,28 cases as malignant lesions group,22 cases of benign lesion group.Choose the same health check colon pathological examination in 30 cases as the control group.All subjects underwent retrograde retention enema method combined with real-time contrast-enhanced ultrasonography and compared among the three groups by quantitative parameters of testing object arrival time,the peak time,rise time,based on the strength, peak intensity and relative value.Results Malignant lesions group peak intensity and intensity of the detected object relative values were significantly higher than those of the control group and benign lesion group,time of arrival,reached peak time were significantly shorter than the control group and benign lesion group,differences were statistically significant（P0.05）;at the same time, benign lesion group peak intensity and intensity of the detected object is affected by the relative values were significantly higher than those of the control group,arrival time,the peak time were significantly shorter than that of the control group,differences were statistically significant（P0.05）.Conclusion Retrograde retention enema method combined with real-time ultrasound imaging can accurately distinguish normal colon tissue and diseased tissue.At the same time on lesions of benign and malignant made more reliable identification,in the clinical diagnosis of colonic lesions has important value.
