摘　　要：目的分析多层螺旋CT(MSCT)对食管下段、贲门胃结合部癌的早期诊断价值。方法回顾性分析本院2017年6月至2019年5月收治的70例食管下段、贲门胃结合部癌患者的临床资料,观察MSCT检查所得结果进行诊断分析;以病理检查为"金标准",评估MSCT检查对食管下段、贲门胃结合部癌术前T、N分期的诊断准确率。结果以病理诊断为"金标准",MSCT对食管下段、贲门胃结合部癌术前T分期诊断准确率为67.14%,对食管下段、贲门胃结合部癌术前N分期的诊断准确率为87.14%;食管下段、贲门胃结合部癌在MSCT图像上可见贲门及食管管壁呈环状或结节状增厚,管腔变小而不规则;贲门呈鸟嘴样变浅39例,鸟嘴消失呈向内突起改变31例;受侵胃底、胃体及胃窦壁增厚;增强扫描轻到中度均匀强化;其中有21例患者发现淋巴结转移,9例发现肝转移。结论MSCT检查可清楚显示食管下段、贲门胃结合部癌的影像学特点,对早期食管下段、贲门胃结合部癌敏感性强,对肿瘤分期可做出准确判断,为临床医师提供重要的参考,值得广泛应用。Objective To analyze the value of multi-slice spiral CT(MSCT)in the early diagnosis of lower esophageal and gastric cardia cancer Method The clinical data of 70 patients with lower esophageal and cardiastomach junction cancer who were admitted to our hospital from June 2017 to May 2019 were retrospectively analyzed.The results of MSCT examination were observed for diagnosis and analysis.The pathological examination was used as the gold standard to evaluate the accuracy of the MSCT in the diagnosis of preoperative T and N staging of lower esophageal and cardia-stomach junction cancer Result With a pathological diagnosis as the gold standa rd,the accu racy rate of preoperative T staging of MSCT for preoperative esophageal and gastric ca rdia cancer was 67.14%,and the accu racy of preoperative N staging of lower esophageal and gastric cardia cancer was 87.14%;esophagus The lower segment and the gastric cardia junction cancer showed that the cardia and esophageal wall were thickened or nodular thickened on the MSCT image,and the lumen became small and irregular.The ca rdia was shallow in a beak-like manner in 39 cases,and the beak disappea red.Intra-protrusion changes in 31 cases;invaded gastric fundus,corpus,and antral wall thickening;enhanced scan light to moderate uniform enhancement;21 patients found lymph node metastasis.9 patients found liver metastasis.Conclusion MSCT examination can clearly show the imaging features of the lower esophageal and ca rdia-stomach junction cancer,and it is sensitive to the early lower esophageal and ca rdia-stomach junction cancer.It can make accurate judgments on tumor staging,which provides an impo rtant reference for clinicians.Worth widely used.
