Abstract:
Objective To discuss the value of oral contrast ultrasonography (OCUS) in the screening of gastric and duodenal disease in asymptomatic people in rural communities.Methods An OCUS screening was conducted in 3240 residents of Chongming County in Shanghai. After taking oral ultrasonic contrast agent, real-time observation of cardia, gastric fundus, gastric body and gastric angle, gastric antrum and duodenal bulb was conducted for each subject to detect the cardiac diameter, the body of the stomach wall thickness, pyloric canal diameter and each part of the form and structure. All subjects with abnormal sonogram were examined by gastroscopy.Kappa test was used to analyze the consistency between OCUS screening results and pathological results.Results OCUS screening detected a total of 51 cases of various types of gastric and duodenal lesions, the total detection rate was 1.57％. The coincidence rate between screening results and gastroscopy/pathology examination was 93.75％ (45/48) with a good consistency (Kappa=0.905). Five cases of gastric cancer with the detection rate of 0.15％ (5/3240) were found.Conclusion OCUS can be used for the screening of gastric and duodenal diseases in the rural community, and it is worth further research and evaluation.
