Upper gastrointestinal (GI) abnormalities are one of the most common disease in clinical practice, and among them, gastric cancer is one of the most common causes of cancer-related death in China. However, conventional trans-abdominal ultrasound is difficult to evaluate GI diseases due to gas filled in the GI tract. With the development of oral contrast agents in China, ultrasonography with oral contrast agent has been used to visualize upper GI tract (i.e., stomach and duodenum) as well as its surrounding structures. The primary purposes of this consensus and guideline written by Chinese experts is to provide a coherent and clinical perspectives and practical protocol for using oral contrast in upper GI ultrasound, including four components: (1) indications and contraindications of gastric contrast ultrasound; (2) patients and instruments preparation; (3) scanning technique and imaging acquisition; (4) diagnosis of upper GI abnormalities.
