Abstract:
Objective To compare the diagnostic accuracy of endoscopic ultrasonography (EUS) and CT for gastric submucosal tumors of different sizes and properties. Methods 80 patients with gastric submucosal masses treated in our hospital from January 2016 to January 2022 were examined by EUS and CT, and the diagnostic results of EUS and CT were compared and analyzed. Results Postoperative pathology confirmed that 60 cases were benign tumors and 20 cases were malignant tumors, the accuracy of EUS in diagnosing gastric submucosal masses was 97.50%, which was significantly higher than that of CT81.25% (P<0.05). For gastric submucosal masses with tumor diameter < 1 cm, the diagnostic accuracy of EUS was 93.33%, which was significantly higher than that of CT73.33% (P<0.05). There was no significant difference in diagnostic accuracy between EUS and CT for gastric submucosal masses with tumor diameter of 1~2 cm and tumor diameter > 2 cm (P>0.05). Gastric submucosal mass with tumor diameter < 1 cm, the accuracy of EUS was 96.67%, which was significantly higher than that of CT83.33% (P<0.05).There was no significant difference in the accuracy of EUS and CT in diagnosing malignant gastric submucosal masses (P>0.05). The proportion of uniform echo and clear boundary in malignant stromal tumor was 30.00% and 35.00%, which was significantly lower than that in benign gastric stromal tumor 79.55%、81.82% (P<0.05), The proportions of malignant gastric stromal tumors with irregular shape, uneven enhancement, necrosis and local invasion were 65.00%, 70.00%, 60.00% and 65.00% respectively, which were significantly higher than those of benign gastric stromal tumors (P<0.05). Conclusion Compare with CT examination, EUS has better application value in the diagnosis of gastric submucosal tumors, especially in tumor
