Objective: To investigate the effect of endoscopic ultrasound real-time tissue elastography in differential diagnosis of benign and malignant digestive system tumors. Methods: Forty-two patients with solid tumors of digestive system who were admitted to our hospital between October 2017 and October 2018 were selected. All patients were diagnosed by endoscopic ultrasound real-time tissue elastography. Elastography score was used. The strain ratios (SR) of the lesion and the surrounding control tissues were measured and compared. Results: Lesions with elastography score no more than two points were evaluated as benign, while lesions with elastography score no less than three points were evaluated as malignant. The difference of the elastography score between the benign lesion group and malignant lesion group was statistically significant (P<0.05). The sensitivity, specificity and accuracy of endoscopic ultrasound elastography in the diagnosis of malignant tumors of digestive system were 91.4%, 88.9% and 87.5%, respectively. The SR of the benign lesions ranged from 0.01 to 7.34, with a median SR of 7.33; the SR of the malignant lesions ranged from 1.01 to 47.66, with a median SR of 20.07. The SR of the benign lesions was significantly lower than that of the malignant lesions (P<0.05). Conclusion: Elastography of benign and malignant tissues of digestive tract tumors has different image characteristics. Endoscopic ultrasound real-time tissue elastography is effective in differential diagnosis of digestive tract tumors as it can effectively determine whether a tumor is benign or malignant and improve diagnostic accuracy. doi: https://doi.org/10.12669/pjms.35.5.1075 How to cite this:Lv H, Zhu G, Zhou L.

Abstract: 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 real-time 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.

To evaluate diagnostic performance of real-time tissue elastography (RTE) with a low frequency convex array probe for distinguishing benign from malignant hepatic tumors through trans-abdominal examination, elasticity images of 210 liver tumors were obtained by EUB-7500 (Hitachi Medical Systems and 3.5 MHz probe) and eventually 121 liver tumors were analyzed in the study. Elasticity images were classified into four types, from type a to d. Regarding type a or b as benign tumors and type c or d as malignant ones, sensitivity, specificity, and accuracy were calculated and the consistency between the findings of RTE and the pathohistological diagnosis was evaluated. The sensitivity, specificity, and accuracy were separately 97.2%, 88.0%, and 93.4% (P<0.001). Moreover, there was a good consistency between the findings of RTE and the pathological diagnosis (kappa value 0.86). Among elasticity images of all the malignant tumors, the hepatocellular carcinomas (HCCs) mainly appeared in type c, and liver metastatic cancers in type d. Thus, RTE utilized as a novel noninvasive imaging examination method enables us to distinguish benign from malignant liver tumors. Moreover, it provides certain information for the differential diagnosis between HCCs and liver metastatic cancers.
