目的探讨低张水灌肠螺旋CT扫描在结、直肠病变中的应用价值。方法对36例已知和临床高度怀疑结、直肠病变的患者,行低张水灌肠螺旋CT扫描及三维重建。结果36例中大肠癌23例,结肠炎4例,大肠转移性肿瘤2例,息肉4例(1例腺瘤性息肉,3例增生性息肉),淋巴瘤2例,平滑肌瘤1例。结论水灌肠螺旋CT扫描对大肠病变尤其是肿瘤性病变具有很高的诊断价值,对大肠癌的分期作用显著。
Objective To investigate the value of low-tension water enema spiral CT in the diagnosis of colorectal lesions. Methods Thirty-six patients with known and highly suspected colorectal lesions were treated with low-pressure water enema spiral CT scan and 3D reconstruction. Results Among the 36 cases, there were 23 cases of colorectal cancer, 4 cases of colitis, 2 cases of colorectal metastasis, 4 cases of polyps (1 case of adenomatous polyps and 3 cases of proliferative polyps), 2 cases of lymphoma and 1 case of leiomyoma. Conclusion Water enema spiral CT scan has high diagnostic value on colorectal lesions, especially oncological lesions, and has a significant staging effect on colorectal cancer.
