Pill gastroscopy may vary in price from region to region and from hospital to hospital, generally around$2000-4000. The advantage of pill gastroscopy over regular gastroscopy is that it is essentially a painless experience for the patient during the examination, it does no harm in the body and is excreted in the stool in about 3 days. Pill gastroscopy also has some side effects and is very inconvenient for patients who need pathological biopsies for puncture, as the capsule gastroscope does not have control over where it stays. It is recommended to choose different gastroscopy modalities according to the actual situation of the patient. The painless gastroscopy commonly used in clinical practice is also an electronic gastroscope, but it is relatively speaking basically painful for the patient, and it can also perform pathological biopsy in time.
