摘要
目的:探讨直肠低张充气后16层螺旋CT扫描对直肠癌的诊断价值。方法:对临床内镜诊断或临床怀疑直肠癌的147例患者进行低张充气灌肠后用16层螺旋CT进行容积平扫和增强扫描;观察内容包括:①肿瘤部位、大小;②平扫和增强的情况;③生长方式;④侵犯层次;⑤管周筋膜情况;⑥管周淋巴结有无肿大;⑦盆腔淋巴结肿大情况;⑧远处有无转移。结果:147例患者顺利完成低张直肠充气16层螺旋CT平扫和增强扫描,肠道准备满意;直肠低张充气后16层螺旋CT扫描检查出所有直肠肿瘤样病变,敏感性是100%,准确性95.77%;147例病例的影像学分期分别是:A期26例,占17.68%(26/147);B期18例,占12%(18/147);C期64例,占43.5%(64/147);D期39例占26.5%(39/147)。影像与病理Dukes分期的对比结果显示影像分期的准确性分别是:A期92%,B期94.12%,C期96.97%,D期100%。结论:低张直肠充气16层螺旋CT检查是直肠癌术前检查的较好的方法,能对直肠癌提供准确的诊断及术前分期。
Objective：To evaluate diagnostic value of 16-sliee spiral CT hypotonic pneumoeolon for reetal carcinoma. Methods： 147 patients diagnosed by endoscope or suspicious of having rectal carcinoma in clinical diagnosis underwent 16-slice spiral CT vohane plain scans and enhancement scanning after hypotonic coloclyster; To observe the content including- （1）the location and size of tumor;（2）the manifestatinon of plain scans and enhancement scanning; （3）the growth pattern of tumor; （4）the encroachment range of tumor; （5）the condition of peri-rectum fascia; （6）the lymphadenectasis in peri-rectum ;（7）the condition of the lymphadenectasis in cavitas pelvis; （8）the condition of distant metastasis.Results： 147 patients successfully accomplished 16-slice spiral CT plain scanning and enhancement scanning hypotonic pneumocolon, the bowel preparation were satisfected; All of rectal tumor-like lesion were checked out by 16-slice spiral CT hypotonic pneumocolon, the accuracy rate of SCT scanning the rectal tumor-like lesion was 95.77%, the sensitivity was 100%. The imageology staging of 147 patients were A stage 24 patients, 16.33% （24/147） ; B stage 15 patients, 10.02% （15/147） ; C stage 68 patients, 46.26% （68/147）; D stage 40 patients,27.21% （40/147）. The accuracy rate of imageology staging contrasted to pathology Dukes staging were A stage 92%, B stage 94.12%, C stage 96.97%, D stage 100%. Conclusion：The 16-slice spiral CT hypotonic pneumocolon is a much better method in rectal carcinoma preoperative examination, and providing accurate preoperative staging and diagnosis for rectal carcinoma.
