目的 探讨CT仿真内镜在结肠癌诊治中的临床应用。方法 收集 30例结肠癌的CT仿真内镜、电子结肠镜及手术病理的材料 ,并从肿块分型、病变环周侵犯范围及病变长度等三方面进行比较。结果 结肠癌的CT仿真内镜征象分析 :(1)肿块分型 :肿块型 11例、溃疡型 11例、浸润型 8例。 (2 )环周侵犯范围 :侵犯肠腔≤ 1/2共 4例、侵犯肠腔 1/4- 3/4共 6例、侵犯肠腔≥ 3/4共 2 0例。 (3)病变长度 :1.0 - 3.0cm共 7例 ,3.1- 5 .0cm共 10例 ,5 .1- 1.0cm共 13例。CT仿真内镜、电子结肠镜与手术病理结果对照 :(1)CT仿真内镜与手术病理结果比较 :肿块分型相同 2 6例 ,不同 4例 ;环周侵犯范围相同 2 5例 ,不同 5例 ;病变长度相同 2 3例 ,不同 7例。 (2 )电子结肠镜与手术病理结果比较 :肿块分型相同 2 2例 ,不同 8例 ;环周侵犯范围相同 2 8例 ,不同 2例 ;病变长度相同 14例 ,不同 3例 ,电子结肠镜不能确定病变长度 13例。结论 CT仿真内镜能获得类似电子结肠镜所见的图像 ,可以作为不能进行电子结肠镜检查 ,或电子结肠镜检查观察不全面的结肠癌患者的一种良好补充检查手段。
Objective To investigate the clinical application of CT virtual endoscopy in the diagnosis and treatment of colon cancer. Methods CT virtual endoscopy, electronic colonoscopy, and surgical pathology were collected from 30 cases of colon cancer, and compared from the three aspects of mass classification, extent of lesion surrounding the lesion, and lesion length. Results CT virtual endoscopic analysis of colon cancer: (1) Lump type: 11 cases of mass, 11 cases of ulcer, and 8 cases of infiltration. (2) Peripheral invading range: Invading the intestine cavity ≤ 1/2 in 4 cases, invading the intestine cavity 1/4- 3/4 in 6 cases, and invading the intestinal cavity ≥ 3/4 in 20 cases. (3) Lesion length: 1.0-3.0cm in total 7 cases, 3.1-5.0cm in 10 cases, and 5-1.1-cm in 13 cases. CT virtual endoscope, electronic colonoscope and surgical pathological results were compared: (1) CT virtual endoscopy and surgical pathological results: The same type of mass was used in 26 cases and different in 4 cases; the range of circumferential invasion was the same in 25 cases, different in 5 cases. Cases; the same length of lesions in 23 cases, different in 7 cases. (2) Comparison between the electronic colonoscope and the surgical pathological results: The same type of mass was used in 22 cases and different in 8 cases; the extent of circumferential invasion was the same in 28 cases and different in 2 cases; the length of the lesion was the same in 14 cases and different in 3 cases. Unable to determine the length of the lesion in 13 cases. Conclusion CT virtual endoscopy can obtain images similar to those seen with electronic colonoscopy. It can be used as a good supplementary examination method for patients with incomplete colon cancer who cannot be screened by electronic colonoscopy or electronic colonoscopy.
