目的 评估仿真CT肠镜在结直肠镜证实的增殖性病灶中的检出能力及其临床应用前景。方法 2 3例结肠镜检查发现异常的患者在 1h内行腹腔和盆腔薄层螺旋CT扫描 ,扫描数据经特殊软件处理后作二维和三维图像重建 ,将CT肠镜诊断结果与全结肠镜、病理和手术结果进行对比研究。结果 2 0例结肠镜诊断为结直肠癌和 1例为结肠狭窄原因待查者 ,CT肠镜诊断为结肠癌 ,并得到病理和手术证实 ;11mm以上的结直肠息肉结肠镜和CT肠镜都作出了正确的诊断 ,CT肠镜发现 6～ 10mm结直肠息肉 19枚 ,其中 13枚的部位和大小与结肠镜描写的基本一致 ,6例新发现病灶中 2例为假阳性。CT肠镜对 2 1例肿瘤的定位诊断与手术发现一致 ,2例结肠镜定位出现偏差。结论 CT肠镜在结直肠癌和直径 6mm以上息肉样病变诊断上有较高的临床价值 ,对各种原因引起的狭窄内镜无法通过和不能耐受全结肠镜检查者 ,则CT肠镜似更有诊断价值
Objective To evaluate the detection ability of simulated CT colonoscopy in colorectal-confirmed proliferative lesions and its clinical application prospects. Methods Twenty-three cases of patients with abnormal colonoscopy were examined by thin-slice abdominal and pelvic CT scan within 1h. The data were reconstructed by special software and two-dimensional and three-dimensional images were reconstructed. The diagnostic results of CT colonoscopy were compared with those of colonoscopy, And surgical results were compared. Results 20 cases of colonoscopy diagnosed as colorectal cancer and 1 case of colon stenosis to be investigated, CT colonoscopy diagnosed as colon cancer and confirmed by pathology and surgery; 11mm colorectal polyps and colostomy colonoscopy are Made the correct diagnosis, colostomy colonoscopy found 6 ~ 10mm 19 colorectal polyps, of which 13 parts and size and colonoscopy description of the basic, 6 cases of newly found lesions in 2 cases were false positive. CT colonography of 21 cases of tumor localization and surgical findings found consistent, 2 cases of colonoscopy positioning deviation. Conclusion CT colonoscopy in the diagnosis of colorectal cancer and polypoid lesions more than 6mm in diameter have a higher clinical value, for a variety of reasons can not pass through the narrow endoscopy and can not tolerate colonoscopy, the CT colonoscopy like More diagnostic value
