objective: to study and analyze the effect of real-time endoscopic ultrasonography in the differential diagnosis of gastrointestinal tumors.Selection methods: between January 2014 and January 2015 xinyang 53 cases of digestive system cancer patients admitted in hospital, a total of 79 substantial tumor of the digestive system lesions, all patients were diagnosed by endoscopic ultrasonography real-time tissue elastography, use elastic imaging score, for patients with lesions and their surrounding structures control the elastic strain rate ratio of measure and comparison analysis.Results: compared with the malignant lesion group, the difference between the benign lesion group and the benign lesion group was statistically significant (P<0.05).The ratio of elastic strain rate in benign lesion group was lower than that in malignant lesion group (P<0.05).The diagnostic accuracy, sensitivity and specificity were 91.14%, 94.74% and 81.82% respectively.Conclusion: endoscopic ultrasound realtime tissue elastography is effective in the differential diagnosis of digestive system tumors, and can effectively determine the benign and malignant tumors and improve the diagnostic accuracy.
