目的 探讨结肠癌的低张结肠造影CT诊断价值。方法 收集我院近 6年临床诊断肠梗阻、腹部肿块或 (和 )结肠灌肠X线造影疑为结肠癌的病例 5 5例 ,行低张结肠水 (或 3 %泛影葡胺 )灌注造影CT扫描 ,对手术病理证实的 3 5例CT片进行回顾分析。结果 3 4例手术病理结果与CT诊断相符 ,其中 3 3例为结肠腺癌 ( 1例伴肠套叠 ) ,1例为腹腔多发转移性腺癌。 1例手术病理为“回盲部炎症、肉芽组织增生”误诊为结肠癌。 3 5例中 2 1例同时行结肠造影 ,15例诊断为结肠癌 ,1例造影正常 ,1例造影失败 ,4例为假阴性结果。结论 对临床情况允许的病例采用低张结肠水灌注CT扫描 (肠梗阻病人宜用 3 %泛影葡胺液灌注 ) ,能清晰显示病变原发灶 ,梗阻部位、范围 ,周围脏器等。优于常规CT和X线检查
Objective To investigate the diagnostic value of low-contrast colonography in colon cancer. Methods Fifty-five cases of colon cancer diagnosed as intestinal obstruction, abdominal mass or (and) colon enema X-ray angiography in our hospital in recent 6 years were enrolled in this study. Low-density colon water (or 3% diatrizoate) Scanning, 35 cases of CT confirmed by surgical pathology were retrospectively analyzed. Results The pathological findings of 34 cases were consistent with CT diagnosis, of which 33 cases were colon adenocarcinoma (1 case with intussusception) and 1 case was peritoneal multiple metastatic adenocarcinoma. One case of surgical pathology as “ileocecal inflammation, granulation tissue hyperplasia” misdiagnosed as colon cancer. Of 35 cases, 21 cases had colonic angiography at the same time, 15 cases were diagnosed as colon cancer, 1 case had normal angiography, 1 case failed angiography and 4 cases had false negative results. Conclusion The cases of clinical conditions allow the use of low-tension colon water perfusion CT scan (intestinal obstruction patients should use 3% diatrizoate gavage), can clearly show the lesion, obstruction site, scope, and other organs around. Superior to conventional CT and X-ray examination
