Abstract: Objective  To evaluate the value of oral contrast-enhanced transabdominal ultrasound in the diagnosis of gastric lesion. 
Methods  A total of 130 patients with stomach discomfort in our hospital were examined by the oral contrast-enhanced transabdominal ultrasound.The oral contrast-enhanced transabdominal ultrasound results were compared with gastroscopy or other imaging examinations. 
Results  In 130 cases, there were 113 cases of stomach diseases. There were 44 cases of gastritis by oral contrast-enhanced transabdominal ultrasound, and the diagnostic coincidence rate was 87.6%. There were the 13 cases of gastric cancer, the 7 cases of gastric stromal tumor, the 17 cases of gastric ulcer, the 15 cases of gastric polyps, and the 3 cases of hiatal hernia diagnosed by oral contrast-enhanced transabdominal ultrasound. The diagnostic rate of oral contrast-enhanced transabdominal ultrasound was 88.2%.   
Conclusion  In the diagnosis of gastric lesion，the oral contrast-enhanced transabdominal ultrasound are used,non-invasive, non-radiative, simple and easy to be performt, and it has a good diagnostic coincidence rate for stomach diseases. It can be used as the first choice for screening gastrointestinal diseases, supplementing the gastroscope and upper gastrointestinal angiography.
