【摘要】：目的探讨超声双重造影(DCEU)对大肠肿瘤筛查的临床应用价值。方法 (1)受检查者先行常规经腹壁超声检查(CTU),然后清洁肠道,将胃肠声学造影剂从肛门灌入肠道后,再进行大肠充盈型造影超声检查(IFCU)。(2)对怀疑大肠肿瘤者进行静脉造影超声检查(ICEU)、纤维肠镜及病理学检查。(3)DCEU、纤维肠镜、病理学检查三者结果进行对比分析,经统计学处理后,研究DCEU对大肠肿瘤筛查的临床应用价值。结果 (1)CTU及IFCU检查266例,DCEU检查45例;经病理学检查确诊大肠肿瘤41例,CTU发现20例,DCEU发现39例,表明DCEU对大肠肿瘤的筛查更具检出性(χ2=21.81,P=0.00)。(2)大肠肿瘤DCEU声像图各具特点。(3)DCEU对大肠肿瘤定位准确率较CTU明显增高(χ2=28.15,P=0.00)。(4)对良、恶性大肠肿瘤定性符合率DCEU为88.89%、96.88%,纤维肠镜为100%、93.75%,DCEU及纤维肠镜对大肠肿瘤的检出均是有效的(P0.05)。结论大肠双重超声造影检查法为大肠肿瘤好发人群筛查提供有效可行的手段,具有重要的临床推广应用价值。
[Abstract]:Objective to investigate the value of double contrast-enhanced ultrasonography (DCEU) for colorectal cancer screening in the clinical application. Methods (1) were examined by routine transabdominal ultrasonography (CTU), and then clean the intestinal tract, gastrointestinal tract contrast agent into the intestinal tract from the anus after irrigation, then E. filling type contrast sonography ((IFCU). 2) intravenous contrast enhanced ultrasound examination of suspected colorectal tumor (ICEU), fiber colonoscopy and pathological examination. (3) DCEU, colonoscopy, pathological examination of the three results were analyzed by statistical treatment, clinical application value of DCEU for colorectal cancer screening. Results (1) CTU and IFCU in 266 cases, 45 cases of DCEU examination; pathology confirmed 41 cases of colorectal cancer, 20 cases were found by CTU, 39 cases were found by DCEU, showed that DCEU screening for colorectal cancer is more detection of (x 2=21.81, P=0.00). (2) colorectal tumor DCEU sonographic characteristics. (3) DCEU colorectal neoplasms The positioning accuracy was significantly higher than that of CTU (2=28.15, P=0.00). (4) of benign and malignant colorectal tumors, qualitative coincidence rate of DCEU was 88.89%, 96.88%, 93.75%, 100% for colonoscopy, DCEU and colonoscopy detection of colorectal cancer are effective (P0.05). Conclusion ultrasound imaging method of double E. for colorectal tumor screening and provide a feasible and effective method, and has important clinical application value.
