[Abstract]:Objective 1. To summarize the enhanced CT findings of anastomotic recurrence after esophageal cancer operation by using MDCT enhanced scanning. To investigate the related factors of anastomotic recurrence after esophageal cancer operation. Methods: 74 cases of esophageal carcinoma proved by gastroscopy were retrospectively analyzed. Contrast-enhanced MDCT scan data after operation, According to CT signs and pathological results, we divided into 3 groups: normal anastomosis group (n = 28), benign thickening group (n = 22) and malignant thickening group (n = 24). The median age was 64.39 years, with an average age of 63.7 鹵7.6 years. The median time from January to 8 years was 28.39 鹵27.22 months, and the median time was 19.27 months. Toshiba AquilionTM ONE 320 slice CT was used. First, 120kV of 200mAs, 5mm thick, 5mm interval, and then injected with 50 ~ 80ml of contrast agent and 300mgI / ml of iopramide through cubital vein mass. Dynamic trigger examination was used to select the descending aorta with trachea bifurcation level, and the area of interest was refion of interest. After the CT value of ROI reached 200HU, the arterial phase scan was delayed for 10 s and the venous phase scan was performed after 40 s. All the images were transferred to the workstation Vitrea FX Version6.3 for multiplanar reconstruction and coronal image reconstruction, and all the images were transferred to the workstation Vitrea FX Version6.3 for multiplanar reconstruction. The thickness of sagittal reconstruction was 5 mm. The difference was statistically significant by using SPSS19.0 statistical software to analyze the sagittal reconstruction thickness. To analyze the correlation between benign and malignant thickening of anastomotic stoma and CT features, a comparative analysis of the wall thickness of anastomotic area in n _ 1n _ 2n _ 3 group was carried out by single factor variance analysis and Spearman grade correlation analysis. Correlation analysis was carried out. Age was analyzed by chi-square test. Sex, pathological type, location of primary tumor, degree of differentiation, T stage and clinical stage were analyzed by univariate analysis and multivariate analysis by logistic. Results: 1. Normal anastomotic site group. There was significant difference in wall thickness between benign thickening group and malignant thickening group. The critical value of wall thickness in benign thickening group and malignant thickening group was 17.2 mm, and the sensitivity was 68.2 mm. The mucosal disruption of narrow segment was associated with malignant thickening of anastomotic stoma after esophagus cancer operation, and the correlation was higher (eccentricity thickening, eccentricity thickening). Lumen mass with uneven enhancement, irregular upper and lower margin of thickened wall, interrupted mucous membrane of narrow segment, enhancement amplitude of arterial phase and malignant thickening of anastomotic stoma were related to malignant thickening of anastomotic stoma. There was no statistical significance in the differentiation of malignant thickening. The correlation coefficient of enhancement amplitude in arterial phase was 0.45, the critical value of arterial enhancement in benign and malignant thickening group was 19.09 Hu. the sensitivity was 72.7%. The OR values related to anastomotic recurrence in stage 鈪,
