It is possible to miss the diagnosis when doing gastroscopy with gas injection, but the possibility of misdiagnosis is very small.
The diagnosis of gastroscopy is based on the endoscopic manifestations observed by the examiner. Due to the level problem of the operator and the clarity problem of the gastroscope, some of the tiny intragastric lesions can not be detected, especially tiny cancers, which have a diameter of less than 1 millimeter, and then it is easy to miss the diagnosis.
If there is a gastric lesion, the diagnosis should also be combined with pathological tissue examination. The glands and cells can be observed through magnifying microscope, which usually helps to make a clear diagnosis, so the possibility of misdiagnosis is relatively small. However, if there are no problems, such as erosion, polyps, ulcers, tumors, etc., the stomach belongs to the normal stomach, and misdiagnosis usually does not occur.
Patients are advised to visit a regular hospital for timely detection of the disease and targeted treatment.
