Definitive diagnosis: When patients have a series of digestive symptoms such as unexplained abdominal pain, bloating, acid reflux, vomiting, vomiting blood, etc., they should undergo gastroscopy to find out whether there are ulcers, gastritis, esophagitis, pyloric obstruction and other digestive system diseases.
2. Endoscopic treatment: When there is acute upper gastrointestinal bleeding, gastric polyps, early tumors, endoscopic treatment such as titanium clip for hemostasis, esophagogastric fundal variceal ligation, endoscopic mucosal dissection (ESD), etc. can be performed to treat different digestive diseases.
3. Early cancer screening: People over 40 years old can undergo gastroscopy during physical examination to detect early tumors in the digestive tract.
