Capsule gastroscopy and ordinary gastroscopy compared to ordinary gastroscopy, ordinary gastroscopy is relatively more accurate. Capsule gastroscopy only requires the patient to drink water and swallow a capsule endoscope, and the examination process of the stomach can be completed in 15~30 minutes, which has the advantages of non-invasive, painless and easy to operate. However, capsule gastroscopy is not controllable in the body, and may miss certain parts of the photo, etc., which cannot provide detailed image information for the doctor’s diagnosis. Ordinary gastroscopy, on the other hand, requires the lens to be adjusted and then inserted into the patient’s digestive tract for observation, which is able to observe the stomach in detail and save more detailed image data, making it easy to detect early and tiny lesions with a higher degree of accuracy than capsule gastroscopy. However, ordinary gastroscopy is not comfortable, patients may have nausea, vomiting and other uncomfortable symptoms, and anesthesia is also required before painless gastroscopy operation. Patients who need to undergo gastroscopy should ask their doctor to make a judgment and choose the gastroscopy that is suitable for them.
