低张水灌肠螺旋CT扫描对大肠癌的诊断价值

The value of hypotonic water enema spiral CT in the diagnosis of colorectal carcinoma

目的分析低张水灌肠螺旋CT扫描的大肠癌影像表现进而评估其诊断价值。方法对31例经纤维结肠镜或手术病理证实的大肠癌患者的低张水灌肠螺旋CT扫描图像进行分析。结果低张水灌肠螺旋CT扫描28例均表现肠壁增厚,3例表现为结节样软组织影突向肠腔。其中7例可见肠梗阻表现,1例可见肠套迭影像,1例可见伴发有阑尾炎表现,5例有肝转移病灶,4例可见腹膜后大血管旁肿大的淋巴结。

Objective To analyze the images of colorectal carcinoma on hypotonic water enema plus spiral computed tomography scanning(HWE SCT) and to assess the diagnostic value.Methods Thirty-one patients with colorectal carcinoma confirmed by colonofibroscope or operation underwent HWE SCT examinations.Imaging findings in all patients were analyzed retrospectively.Results HWE SCT directly demonstrated the thickening of bowel wall in 28,nodular soft tissue shadows herniated toward the bowel cavities in 3.Simultaneously,HWE SCT also showed other associated lesions such as interstinal obstruction in 7,intussusception in 1,appendicitis in 1,hepatic metastasis in 5,and the swelling of lymph nodes in post-peritonei in 4.Conclusion HWE SCT is a better method for diagnosing co1orectal carcinoma.
