What examination can replace gastroscopy?

Barium meal examination, capsule endoscopy and stomach ultrasound examination can replace gastroscopy to some extent, but gastroscopy has a high accuracy and is the gold standard for diagnosing stomach diseases. 1, barium meal barium meal examination patients need to take barium agent orally, and then observe the barium agent flow in the human digestive system under X-ray irradiation, can observe whether there are ulcers, hyperplasia and other lesions in the stomach, suitable for people who cannot take gastroscopy. Because barium agent does not adhere to the place in the human body, it cannot stay, so it is impossible to carefully observe the location of the lesion. If there is a small lesion, it is easy to miss the diagnosis. 2. Capsule endoscopy. Patients swallow the capsule implanted with endoscope, and can observe the lesions of esophagus, stomach, intestinal tract and other related parts. After the capsule enters the digestive tract, it can automatically take high-definition pictures and transmit them to the recorder. Although capsule endoscopy has high clarity, it is impossible to obtain stomach biopsy for pathological examination, so it cannot completely replace gastroscopy. 3, stomach ultrasound examination patients first take contrast agent, followed by stomach B ultrasound, using the reflection principle of ultrasound can see the gastric mucosa layer, muscle layer and serosa layer, can be used to replace gastroscopy can not be deeply detected parts, such as located in the small curvature of the stomach under the serosa lesions.
