1. Will gastroscopy be painful?
Gastroscopy is divided into general gastroscopy and painless gastroscopy. Painless gastroscopy is a gastroscopy after anesthesia. There is no discomfort in the process of gastroscopy. It is a kind of examination that can be completed after sleep. Generally speaking, ordinary gastroscopy is not too painful, because the stomach belongs to visceral innervation, there is no pain during the examination, and there is no feeling even if you take a biopsy. Just as we swallow food and feel almost nothing through our throats. Modern gastroscope is slimmer and softer, and the examination technology is improved. Most patients have only mild discomfort when they undergo gastroscopy. The whole process of gastroscopy will take about 5 ~ 10 minutes. As long as you cooperate with the doctor's guidance and relax, the examination will be over soon.2. Painless gastroscope.Different from ordinary gastroscope, endoscopic ultrasound is a good combination of ultrasound and endoscopy. it places a miniature high-frequency ultrasound probe in front of the endoscope. when the endoscope enters the gastric cavity, the endoscope can be used to observe the shape of the cavity directly. at the same time, endoscope can be used for real-time ultrasound scanning to obtain the histological characteristics of all levels of gastrointestinal tract and the ultrasonic images of surrounding adjacent organs. Its main advantage is that it can determine the depth of gastric cancer invading the gastric wall and the structure of adjacent tissues or organs outside the gastric wall, and can accurately evaluate the degree of tumor invasion, lymph nodes and extragastric metastasis.
