摘　　要：目的探究低张水充盈多层螺旋CT(MSCT)在胃癌TNM分期的诊断价值。方法选取2017年7月~2020年7月在我院就诊的116例胃癌患者,按照随机数表法将患者分为对照组和观察组,58例/组。对照组进行常规MSCT检查,观察组进行低张水充盈MSCT检查,以病理学检查结果为标准,分析两组诊断胃癌TNM分期的准确性。结果两组病理检验TNM分期结果差异无统计学意义(P>0.05),对照组对胃癌患者T1~T4分期的诊断准确性分别为80.00%、70.59%、70.59%和50.00%,总体诊断准确率为70.69%,观察组分别为100%、84.62%、90.48%和80.00%,总体诊断准确率为87.93%;对照组对胃癌患者N0~N2分期的诊断准确性分别为84.00%、73.91%和60.00%,总体诊断准确率为75.86%,观察组分别为90.00%、90.00%和87.50%,总体诊断准确率为89.66%;对照组和观察组对胃癌患者M分期的诊断准确性分别为82.93%、87.93%;观察组T、N分期的诊断准确性高于对照组(P<0.05),两组M分期诊断准确率差异无统计学意义(P>0.05)。结论低张水充盈MSCT诊断胃癌TN分期准确性高于常规MSCT检查,两种方法诊断胃癌M分期效果相近。Objective To explore the diagnostic value of multi-slice spiral CT(MSCT)with hypotonic water-filling method on TNM staging of gastric cancer.Methods A total of 116 patients with gastric cancer who came to the hospital for treatment were selected from July 2017 to July 2020.They were divided into control group and observation group by the random number table method,with 58 cases in each group.The control group underwent routine MSCT examination while the observation group was given MSCT with hypotonic water-filling method.The pathological examination result was used as the standard to analyze the accuracy rates of the two groups in the diagnosis of TNM staging of gastric cancer.Results There were no statistical differences in TNM staging results of pathological examination between the two groups(P>0.05).The diagnostic accuracy rates of T1-T4 stages of gastric cancer and overall diagnostic accuracy rate were 80.00%,70.59%,70.59%,50.00%and70.69%in control group,100%,84.62%,90.48%,80.00%and 87.93%in observation group.The diagnostic accuracy rates of N0-N2 stages of gastric cancer and overall diagnostic accuracy rate were 84.00%,73.91%,73.91%,60.00%and 75.86%in control group,which in observation group were 90.00%,90.00%,87.50%and 89.66%,respectively.The diagnostic accuracy rate of M staging was 82.93%in control group and 87.93%in observation group.The diagnostic accuracy rate of TN staging in observation group was higher than that in control group(P<0.05),but there was no statistical significance in the diagnostic accuracy rate of M staging between the two groups(P>0.05).Conclusion The accuracy of MSCT with hypotonic water-filling method in diagnosing TN staging of gastric cancer is higher than that of routine MSCT examination.The two methods are similar in diagnosing M staging of gastric cancer.
