目的探讨彩色多普勒超声对结直肠癌的诊断价值。方法回顾性分析2005年3月至2011年12月经超声(经腹)诊断为结直肠癌的37例患者的术前声像图特征及临床资料,并与术后病理对照研究,其中误诊3例。结果彩色多普勒超声诊断结肠癌,对于结肠癌病变部位、肠系膜淋巴结转移、肝转移诊断符合率分别为81.8%(30/37)、78.3%(26/37)、92.8%(13/14);对“假肾征”型结肠癌诊断准确率达96%(24/25);总诊断符合率91.8%(34/37)。结论彩色多普勒超声对结直肠癌是一种方便而有效的方法 ,还能了解病变外浸润及转移情况,具有重要的临床诊断价值。
Objective To investigate the diagnostic value of color Doppler ultrasound in colorectal cancer. Methods Retrospectively analyzed the characteristics and clinical data of 37 patients with colorectal cancer diagnosed by ultrasound (abdominal) from March 2005 to December 2011 and compared them with postoperative pathology, of which 3 cases were misdiagnosed . Results The diagnostic accuracy of color Doppler ultrasound in diagnosis of colon cancer was 81.8% (30/37), 78.3% (26/37) and 92.8% (13/14) respectively for the diagnosis of colon cancer, mesenteric lymph node metastasis and liver metastasis. ; The accuracy rate of diagnosing “false kidney syndrome” colon cancer was 96% (24/25); The total diagnosis coincidence rate was 91.8% (34/37). Conclusion Color Doppler ultrasound is a convenient and effective method for colorectal cancer. It can also understand the infiltration and metastasis of extra-corpus and has important clinical diagnostic value.
