Ultrasound of gastrointestinal diseases

The gastrointestinal tract is a cavity organ, often affected by gas. Ultrasound detection from the body surface is not easy to obtain a satisfactory sonogram. The diagnosis of gastrointestinal diseases often depends on gastroscopy and x-ray barium meal examination. In recent years, due to the development and application of two techniques of gastrointestinal acoustic contrast and ultrasound endoscopy, the scope of diagnosis of gastrointestinal diseases has been widened. Ultrasound can clearly show the hierarchical structure of the gastrointestinal wall, find the location, size and morphology of tumors in the gastrointestinal wall, estimate the extent of lesions invading the gastrointestinal wall, especially understand the metastasis of surrounding organs, and make up for the lack of gastroscopy and x-ray examinations Provide a reliable basis for the selection of clinical treatment programs.
