According to Baidu Health, enteroscopy and gastroscopy are two common inspection methods of gastrointestinal endoscopy, which are used to check gastrointestinal diseases. Under normal circumstances, the results of gastrointestinal endoscopy are generally within 1 day. If a tissue biopsy is needed, it may take about 7 days to get the results. Pay attention to cleaning the intestines before the examination, do not eat within 8 hours in advance, and focus on liquid food for 3 days before the examination.
Gastroenteroscope usually refers to enteroscope and gastroscope. Colonoscopy is a slender and flexible medical instrument. The diameter of the anterior lens is about 1cm, which is of great significance for the examination and diagnosis of diseases in the large intestine. At present, it has been widely used in clinic. The scope of colonoscopy includes unexplained lower gastrointestinal bleeding, chronic diarrhea, abdominal mass, middle and lower abdominal pain, intestinal obstruction, suspicious tumors and so on. Gastroscope is the most commonly used and accurate examination method for esophagus, stomach and duodenum. It can not only directly observe mucosal lesions, but also perform biopsy. Generally, it can be used for reflux esophagitis, gastritis, peptic ulcer, gastric cancer and other diseases.
