Abstract：Objective To explore the clinical value of enhancement MDCT diagnosis of anastomotic recurrence after esophagectomy.Methods We conduct a retrospective analysis of the enhancement MDCT scan document of 74 cases of postoperative esophageal cancer proved by endoscopic pathology.It is divided into 3 groups according to CT sign and pathological results.Group A is normal anastomosis (n =28).Group B is anastomotic benign thickening (n =22) and group C is anastomotic malignant thickening (n =24).A comparative analysis on relevant signs of three groups is performed.Results 1) The thickness of the tube wall and the enhancement of the arterial phase in the anastomotic area have certain significance to identify anastomosis (P ＜0.05);2) Mucosal disruption in the narrow segment is relatively high (eccentric thickening,lumen mass,inhomogeneous enhancement,irregular upper and lower edge of pipe wall of thickening,mucosal disruption in the narrow segment,arterial phase enhancement amplitude have certain relevance with malignant thickening of the anastomosis),while thickening of the wall of the ring and the enhancement of venous phase have no statistical significance to the identification of benign and malignant thickening.Conclusion The enhancement MDCT has higher clinical value to the diagnosis of postoperative anastomotic recurrence of esophageal carcinoma.
