Gastroscopy is an upper gastrointestinal endoscopy. Endoscopic biopsy is to find suspicious lesions in the stomach while doing gastroscopy. Insert the biopsy forceps into the stomach through the endoscopic biopsy channel, and then clamp and clamp the tissue. The clamped tissue was fixed and sent to the pathology department, and the nature of the clamped tissue was observed under the microscope. This is a biopsy under gastroscope. Biopsy patients should eat semi-liquid diet within 1 2 days after the examination, and are not allowed to eat cold, hard and irritating food.
