【摘要】：目的:探讨轴位联合多种窗技术和曲面重组(Curved planar reformation,CPR)诊断食管瘘的价值。方法 :回顾性搜集2010年10月—2016年10月期间疑似食管瘘患者110例,所有患者均行MDCT轴位及多种窗技术和CPR成像。利用χ2检验比较轴位联合多种窗技术和CPR诊断食管瘘、确定瘘口位置与轴位诊断结果的差异;以胃镜或随访结果为金标准,采用ROC评价轴位联合多种窗技术和CPR、轴位的诊断效能。利用Wilcoxon检验比较MDCT图像上测量食管瘘口纵向长度与胃镜测量结果的差异。结果:110例可疑食管瘘患者中,食管瘘53例(55处瘘口),均经胃镜、食管造影证实。采用轴位联合多种窗技术和CPR诊断食管瘘效能高于轴位,两者比较有统计学差异,χ~2=8.787,P=0.032;但在确定食管瘘口位置方面无统计学差异,χ~2=0.104,P0.05。CPR脂肪窗测量瘘口长度与胃镜测量结果比较有统计学差异,z=-2.722,P=0.006。CPR纵隔窗上测量结果与胃镜比较无统计学差异,z=-1.807,P=0.071。结论:轴位联合多种窗技术CPR对食管瘘具有独特的诊断价值,可全面评估瘘口部位及范围,提高诊断准确率。
[Abstract]:Objective: to evaluate the value of axial combined with multiple window technique and curved planar reformation (CPRs) in the diagnosis of esophageal fistula. Methods: 110 patients with suspected esophageal fistula from October 2010 to October 2016 were retrospectively collected. All patients underwent MDCT axial imaging and multiple window techniques and CPR imaging. Using 蠂 2 test to compare axial position combined with multiple window technique and CPR to diagnose esophageal fistula, to determine the difference between the location of fistula and axial diagnosis, and to take gastroscopy or follow-up results as the gold standard. ROC was used to evaluate the diagnostic efficacy of axial position combined with multiple windows and CPRs. The difference between the longitudinal length of esophageal fistula measured on MDCT images and the results of gastroscopy was compared by Wilcoxon test. Results among 110 suspected esophageal fistula cases, 53 cases had 55 fistula sites, all of which were confirmed by gastroscopy and esophagography. The diagnostic efficacy of axial combined with multiple window technique and CPR in diagnosis of esophageal fistula was higher than that in axial position. There was statistical difference between the two groups (蠂 ~ 2 / 2 ~ (8.787) P ~ (0.032), but there was no statistical difference in determining the location of esophageal fistula. There was no statistical difference between the measurement of fistula length by 蠂 ~ (2 +) 0.104 ~ (th) P 0.05.CPR and gastroscopy. There was no significant difference between the results of z ~ + -1.807 ~ (?) P ~ (0.071) and that of gastroscopy in the mediastinal window of 蠂 ~ + -2.722 ~ (?) P _ (0.006) CPR. Conclusion: axial combined with multiple window technique CPR has a unique diagnostic value for esophageal fistula, which can comprehensively evaluate the location and range of fistula and improve the diagnostic accuracy.
