目的评价全肠造影ＣＴ检查对肠道肿瘤诊断的价值。方法口服稀碘糖溶液小肠造影即时肛门充氧气大肠造影进行ＣＴ检查，即全肠造影ＣＴ检查。材料选择全肠造影ＣＴ检查、Ｘ线气钡双重对比造影、内镜等检查资料齐全，且有手术和病理证实的４０例肠肿瘤患者进行分析。结果检出最小病灶小肠为０．７ｃｍ，大肠为０．４ｃｍ。结、直肠癌术前与术后的临床病理分期符合率达７０％，良恶性诊断复合率为８７．５％；区域淋巴结转移诊断复合率为８５．７％，肝转移诊断复合率为１００％。结论①检查方法简便安全，对比度好，较小的肿瘤就能被发现。②病变检出率及临床分期准确率高。③对肠道弥漫占位性疾病通过一次检查即能完成病变分布的诊断。④能清楚地显示因结构复杂，其它肠道检查方法易于漏诊部位（如回盲部）的肠道肿瘤。⑤对大肠肿瘤定位准确。
Objective To evaluate the value of CT scanning for the diagnosis of intestinal tumors. Methods Oral dilute iodine solution and small intestine angiography were performed. Anorectal oxygen-enriched intestine angiography was performed for CT examination. The materials were selected for complete bowel contrast CT examination, X-ray double-diaphragm double-contrast contrast, endoscopy and other examination data are complete, and 40 cases of intestinal cancer patients confirmed by surgery and pathology were analyzed. Results The smallest lesion detected was 0.7 cm in the small intestine and 0.4 cm in the large intestine. The coincidence rate of preoperative and postoperative clinical and pathological staging of rectal cancer was 70%, and the combined rate of benign and malignant diagnosis was 87.5%. The combined diagnostic rate of regional lymph node metastasis was 85.7%. The combined rate of diagnosis of liver metastases was 100%. . Conclusion 1 The inspection method is simple and safe, with good contrast, and smaller tumors can be found. 2 The detection rate of lesions and the accuracy of clinical stages are high. 3 Diagnosis of the distribution of lesions can be completed through a single examination on intestinal diffuse space occupying diseases. 4 It can be clearly shown that other intestinal examination methods are easy to miss the diagnosis of intestinal tumors (such as ileocecal) due to complex structures. 5 accurate positioning of large intestine tumors.
