For colonoscopy and gastroscopy, it is usually necessary to register with the Department of Gastroenterology.
Gastroscopy can be used to examine the esophagus, stomach, duodenum, etc., and enteroscopy can be used to examine the rectum, colon, etc., both of which can be used to detect lesions of the digestive organs, so gastroenteroscopy belongs to the category of gastroenterology.
Gastroenteroscopy and colonoscopy can not only visualize the lesions, but also provide endoscopic treatment, such as hemostasis for various gastrointestinal bleeding, endoscopic resection for small polyps or early cancer, and so on. If suspicious lesions are found during the examination, biopsies can be taken through gastroenteroscopy for further examination.
Fasting and other pre-test preparations should be made before colonoscopy and gastroscopy, and if the test results are abnormal, standardized treatment should be carried out under the guidance of doctors.
