What diseases can be examined by gastroscopy?

Gastroscope can check out a variety of diseases, including stomach inflammation, gastric ulcer, stomach tumor, duodenal disease, gastroesophageal reflux disease, gastric polyps, esophageal disease, etc. 1. Gastric inflammation such as chronic gastritis, through gastroscope can clearly observe gastric mucosa congestion, edema, erosion and other manifestations. Gastroscope can directly see the extent and degree of inflammation, providing an important basis for diagnosis and treatment.2. Gastric ulcer can accurately find the ulcer focus in the stomach, including its location, size, shape, depth, etc., but also observe the situation of the mucosa around the ulcer, judge whether there is bleeding, perforation and other complications risk. 3. Stomach Tumors Gastroscopy is an important diagnostic method for stomach tumors such as gastric cancer. It can directly observe the shape and surface characteristics of the tumor, and can perform biopsy to clarify the nature of the tumor. 4. Duodenal diseases such as duodenal ulcer, inflammation, etc. Gastroscopy can enter the duodenum through the stomach for examination, clearly showing the lesion. 5. Gastroesophageal reflux disease can observe inflammatory changes in the lower esophagus, such as congestion, erosion, etc., which is helpful for a clear diagnosis. 6. Gastric polyps can be found in the stomach and its type can be judged. For some polyps that may become malignant, endoscopic resection can be carried out in time. 7. Esophageal diseases include esophagitis, esophageal varices, esophageal tumors, etc. Gastroscopy can comprehensively assess the health status of the esophagus. In short, gastroscopy is a very important examination method, and it has an irreplaceable role in the diagnosis and treatment of upper gastrointestinal diseases such as stomach and esophagus.
