Objective To investigate the diagnostic value of ultrasonography.in elderly patients with gastric tumors.Methods A total of 42 elderly patients with gastric tumors confirmed by surgery pathology underwent oral contrast-enhanced ultrasonography and electronic gastroscopy.The diagnostic effect of oral contrast-enhanced ultrasonography and electronic gastroscopy were compared based on the gold standard of surgical pathology.Results Of the 42 elderly patients with gastric tumors,40 patients were diagnosed by oral contrast-enhanced ultrasonography and the surgical pathology(40/42,95.2％),with Kappa value of 0.812.And 38 cases were diagnosed by electronic gastroscopy and the surgical pathology(38/42,90.5 ％),with Kappa value of 0.718 (P ＜ 0.05).Based on gold standard of surgical pathology results,the accuracies of T1,T2,T3 and T4 stage by oral contrast-enhanced ultrasonography were 95.0％ (38/40),95.0％ (38/40),100.0％ (40/40) and 100.0％(40/40),respectively.The sensitivity and specificity of T3 and T4 stage for oral contrastenhanced ultrasonography reached to 100.0 ％.The diagnostic accuracies of N0,N1-N3,M0 and M1 by oral contrast-enhanced ultrasonography were 95.0 ％ (38/40),95.0 ％ (38/40),100.0 ％ (40/40) and 100.0％(40/40).Conclusions Oral contrast-enhanced ultrasonography is a simple,painless and non-invasive method for the diagnosis of gastric tumors in the elderly.And its qualitative coincidence rate of the tumors diagnosis is similar to that of gastroscopy.So it can be used as the first choice for the examination of gastric tumors in the elderly.Oral contrast-enhanced ultrasonography has a high diagnostic accuracy on TNM staging of gastric tumor.When combined with electronic gastroscopy,it may provide a more reliable basis for the choice of evaluation of treatment and prognosis in elderly patients with gastric tumor.
