Gastrointestinal ultrasonography is still accurate in diagnosing gastritis, gastric ulcers, gastrointestinal tumors, congenital hypertrophic pyloric stenosis, pyloric obstruction, and varicose veins in the fundus of the stomach.
Gastrointestinal ultrasonography, also called gastric filling test, is mainly used to fill up the gastrointestinal cavity through oral administration of contrast medium, so as to observe the structure of the gastrointestinal wall more clearly.
Gastrointestinal ultrasonography has its own advantages and disadvantages compared with gastroscopy and barium X-ray. Compared with gastroscopy, gastrointestinal ultrasonography is less painful, easier to accept, painless and non-invasive, and has no risk of cross-infection.
In addition to mucosal lesions, gastrointestinal ultrasonography can also observe adjacent organs and tissues, such as the pancreas, bile ducts, perigastric lymph nodes and retroperitoneal lymph nodes. It can also assist in clarifying tumor staging when diagnosing neoplastic lesions. Therefore, gastrointestinal ultrasonography is still relatively accurate in the diagnosis of certain diseases.
