低张双重对比CT扫描和后处理技术在胃十二指肠病变中的应用(1)
[摘要] 目的 讨论研究应用低张双重对比CT扫描和后处理技术对检查与诊断胃十二直肠病变的临床价值与意义。 方法 方便选择该院2017年1月—2018年1月收治的怀疑胃十二指肠病变、或经纤维胃镜检查发现胃十二指肠病变需进一步检查的患者100例。对所有患者分别进行低张双重对比造影CT扫描检查并将结果与患者术后病理检查结果进行对照。结果 低张双重对比CT扫描分期人数与手术结果比较得出，I期、II期、III期及IV期判断准确率分别为96.1%、94.1%、93.7%及100.0%;对浆膜受侵程度、周围器官浸润及远处转移判断准确率分别为95.1%、86.4%及86.7%。 结论 在诊断胃十二指肠病变过程中应用低张双重对比CT扫描可对患者胃、十二指肠内壁、肠腔、血管及周围比邻器官等情况进行全面观察。

[Abstract] Objective To discuss the clinical value and significance of low-dose double-contrast CT scanner post-processing technique for the detection and diagnosis of gastro-duodenal lesions. Methods 100 patients with suspected gastroduodenal lesions who were convenient admitted to the hospital from January 2017 to January 2018， or who had gastroduodenal lesions confirmed by fiberoptic gastroscopy for further examination were selected. All patients underwent low contrast double contrast CT scans and the results were compared with postoperative pathological findings. Results Compared with the surgical results， the accuracy of the low-duplex dual-contrast CT scan showed that the accuracy of the I， II， III， and IV stages was 96.1%， 94.1%， 93.7%， and 100.0%， respectively; The accuracy rate of judging the accuracy of peripheral organ infiltration and distant metastasis was 95.1%， 86.4% and 86.7%， respectively. Conclusion In the diagnosis of gastroduodenal lesions， low-dose double contrast CT scan can be used to comprehensively observe the stomach， duodenal wall， intestinal lumen， blood vessels and surrounding organs.

近年来随着社会不断发展及生活压力的日渐增大，不健康的饮食习惯及紊乱的作息规律导致各类消化系统疾病发病人数迅速增加。既往临床多通过口服钡餐并应用纤维內镜方式对疾病进行诊断，但由于口服钡餐多用于观察胃黏膜表面突起，凹陷和黏膜异常，不能观察深层组织的病变，对病灶大小、累及范围等方面不能精确判定;再加上纤维镜检查对胃粘膜下、肌层病变的观察，胃壁外病灶及其累及范围的评估不具优势且过程中造成的恶心、痛苦等不适，使一部分人不愿意接受、或者被迫终止胃镜检查。多层螺旋 CT结合低张双重对比的推广及使用有效弥补了纤维胃镜的不足，不仅能充分显示病变的细微影像解剖结构，更能够清晰反映胃肠壁的血供情况、周围情况以及有无胃肠外脏器病变等。该研究为探讨低张双重对比CT扫描对诊断胃十二指肠病变的意义与价值，方便选取2017年1月—2018年1月该院收治的100例本病患者临床资料进行分析，现报道如下。
