The advantages of gastroenteroscopy are that it is easier to detect lesions, feasible biopsy or treatment, etc., while the disadvantages are that it is difficult to operate and invasive.
Gastroenteroscopy enters into the gastrointestinal tract of the examinee, and can be observed as intuitively and clearly as the human eye, so as to accurately find subtle lesions in the gastrointestinal tract, such as ulcers, erosion, polyps, etc., and biopsies can be taken from the lesions directly or effective treatments can be carried out, such as hemostasis of bleeding points, local medication, and removal of polyps.
However, gastroenteroscopy also has some disadvantages: gastroenteroscopy is difficult to operate, requiring the operator to have professional technical skills, and cannot be popularized. Gastroenteroscopy is an invasive test, and some patients cannot tolerate the discomfort it brings, such as dry heaving, abdominal pain, abdominal distension and other symptoms.
Gastroenteroscopy should be performed in a regular hospital and operated by a specialized doctor, and treated if necessary.
