Can capsule endoscopy replace gastroscope? Which way to check stomach trouble is better?

To be precise, it should be called capsule endoscopy, which is mainly used to examine the small intestine. The stomach cavity is too big to see clearly. Capsule endoscopy has no motivation at all, and it depends on the patient's own gastrointestinal peristalsis. If the patient is well prepared before the examination, some lesions can still be seen, but the found lesions cannot be located and biopsied. After colonoscopy came out, it was basically on the verge of elimination.

Guiding opinions:

There are no side effects, and the only contraindication is that if there is intestinal obstruction, don't check it, so as not to leave the hospital and switch to surgery.
