How many years a gastroscopy can be covered needs to be decided according to the gastroscopic performance. If the results of gastroscopy are normal, a review can usually be performed after 3 years; if the results of gastroscopy are abnormal, such as suggesting gastric ulcer, gastric cancer, etc., a review is required once a year or even once every six months.
Gastroscopy, generally referred to as gastroscopy, can not only visualize mucosal lesions in oropharynx, esophagus, stomach and duodenum, but also conduct pathological biopsy and cytological examination of suspicious lesions to confirm the diagnosis of diseases, and improve the detection rate of early oropharyngeal cancer, early esophageal cancer, early gastric cancer and early duodenal tumor.
Gastroscopy can observe the lesion area in time and can be performed regularly. If the functions of stomach and esophagus are normal, gastroscopy can be carried out once in 3 years; if there is inflammation in the stomach, such as chronic gastritis, acute hemorrhagic gastritis, etc., gastroscopy can be carried out once in 1 year; if there are gastric ulcers, family history of gastric cancer, etc., it is recommended to shorten the time of rechecking.
Gastroscopy needs to go to regular hospitals and be conducted under the guidance of doctors.
