There is no fixed examination cycle for electronic gastroenteroscopy, and the decision needs to be made according to the results of the patient’s first examination and the results of the follow-up review. If the patient has no obvious organic lesions after the e-gastroenteroscopy, and the patient’s age is over 40 years old, it is recommended to review the e-gastroenteroscopy every 5 years, and at the same time pay attention to regular, light eating habits and living habits in daily life. If there are positive lesions in the stomach or intestines when the patient first undergoes EGG, it is recommended that the review cycle of the patient needs to be shortened to half a year to less than a year. If necessary, it is also necessary to combine with the pathologic biopsy under the electronic gastroenteroscopy, according to the results of the examination and treatment to carry out active symptomatic treatment. Patients who need gastroenteroscopy are advised to consult a gastroenterologist in time.
