Abstract:
Objective To assess the diagnostic performance of CT for detecting anastomotic leak after esophagectomy.Methods A total of 50 patients who underwent both CT and fluoroscopy after esophagectomy in our hospital from September 2013 to December 2015 were enrolled in this study.The fluoroscopy features and CT findings were analyzed retrospectively.Results The sensitivity,specificity,positive and negative predictive values were 100%,86.67%,83.33%,100%,respectively,for CT,and 85%,100%,100%,90.91%,respectively,for fluoroscopy.The differences in CT features,including leak of contrast,wall discontinuity and air-fluid collection in the mediastinum were statistically significant between leak and no leak(P=0.000,P=0.000,P=0.005,retrospectively),while no statistically significant in air collection in the mediastinum,hydropneumothorax,pleural effusion and pneumatosis.The maximum diameter of air collection in leak was(1.54±0.97)cm,while the maximum diameter of air collection in no leak was (0.56±0.20)cm,the difference in the maximum diameter of air collection between leak and no leak was statistically significant(P=0.007).Conclusion CT is more sensitive but less specific than fluoroscopy for detecting anastomotic leak.CT can be a better choice for the patients who can not tolerate the fluoroscopy or the fluoroscopy results is negative but anastomotic leak is still suspected.
