多层螺旋CT与消化道造影在胃底贲门癌中的诊断效果研究

Study of Diagnostic Effects in Multi-slice Spiral CT and Gastrointestinal Angiography in Gastric Cardia Cancer

目的探讨多层螺旋CT与消化道造影在胃底贲门癌中的诊断效果。方法选择2016年1月—2018年1月我院118例疑似胃底贲门癌患者作为研究对象,以随机数表法将其分为对照组与研究组,每组各59例。对照组患者术前均行多层螺旋CT检查,研究组在此基础上联合消化道造影检查。以病理检验结果作为诊断标准,对比两组诊断的漏诊率、误诊率、敏感度、特异度、符合率,并分析不同诊断方法下胃底贲门癌的影像表现。结果研究组诊断的敏感度、特异度与符合率均高于对照组(P <0.05),漏诊率与误诊率低于对照组(P <0.05)。研究组对软组织肿块、胃壁增厚、恶性龛影、食管下端狭窄与的黏膜病变的检出率均高于对照组(P <0.05)。结论多层螺旋CT联合消化道造影能够提高胃底贲门癌的诊断效果。

Objective To investigate the diagnostic value of multi-slice spiral CT and gastrointestinal tract angiography in gastric cardia cancer.Methods 118 patients suspected of carcinoma of gastric fundus and cardia from January 2016 to January 2018 were divided into control group and study group by random number table method,59 cases in each group.Patients in the control group were examined by multi-slice spiral CT before operation,and patients in the study group were examined by digestive tract angiography on the basis of multi-slice spiral CT.The missed diagnosis rate,misdiagnosis rate,sensitivity,specificity and coincidence rate were compared between the two groups,and the imaging manifestations of gastric fundus and cardia cancer under different diagnostic methods were analyzed.Results The sensitivity,specificity and coincidence rate of diagnosis in the study group were higher than those in the control group(P<0.05),and the missed diagnosis rate and misdiagnosis rate were lower than those in the control group(P<0.05).The detection rates of soft tissue mass,gastric wall thickening,malignant niche shadow,lower esophageal stenosis and mucosal lesions in the study group were higher than those in the control group(P<0.05).Conclusion Multi-slice spiral CT combined with gastrointestinal angiography can improve the diagnostic effect of gastric fundus and cardia cancer.
