Abstract Objective To study the application value of endoscopic ultrasonography and CT in the diagnosis of esophageal submucosal masses. Methods A total of 103 patients with esophageal submucosal masses detected by gastroscopy from January 2019 to December 2020 in the Affiliated Huaian NO.1 People’s Hospital of Nanjing Medical University were selected as the study subjects. All patients underwent endoscopic ultrasonography and CT examination, and were treated by surgery and diagnosed by pathology. The pathological results, endoscopic ultrasonography and CT findings of all patients were analyzed. The consistency between these two methods and pathological examination in judging benign and malignant tumors of different sizes of esophageal submucosa was compared. Results Pathological results of all patients showed that 8.74% were malignant tumors, all of which were malignant stromal tumors, and 91.26% were benign tumors. Endoscopic ultrasonography showed that the benign mass had clear boundary, smooth surface, and homogeneous or less homogeneous hypoechoic mass. The malignant mass was indistinct with mixed echogenic masses. CT showed that the benign mass had regular shape, oval solid mass, and clear boundary. The malignant mass had uneven density, fuzzy boundary, and uneven enhancement. Endoscopic ultrasonography was consistent with pathological examination (Kappa=0.797, P < 0.05), while CT was consistent with pathological examination (Kappa=0.415, P ＜ 0.05). The diagnostic coincidence rate of endoscopic ultrasound was higher than that of CT, and the difference was statistically significant (P ＜ 0.05). Endoscopic ultrasonography and CT had good consistency with pathological examination in ＞ 2 cm masses (Kappa=1.000, 0.800, P ＜ 0.05). In 1-2 cm masses, endoscopic ultrasonography had a general consistency with pathological examination (Kappa=0.470, P ＜ 0.05), while CT had a poor consistency with pathological examination (Kappa=0.356, P ＜ 0.05). In ＜ 1 cm masses, endoscopic ultrasonography had a general consistency with pathological examination (Kappa=0.642, P ＜ 0.05), while CT had no consistency with pathological examination (P > 0.05). Conclusion Endoscopic ultrasonography and CT have high consistency with pathological examination in the diagnosis of > 2 cm esophageal submucosal masses, which is worthy of promotion.
