Analysis of Influencing Factors of Gastric Preparation Quality for MCCG

The invention of magnetically controlled capsule gastroscopy makes the movement of capsule endoscope in the body controllable. Endoscopic doctors can adjust the angle of capsule observation to examine gastric mucosa according to the need of examination. However, The presence of food residue, air bubbles, mucus and bile in the gastric cavity will affect the observation of gastric mucosa by capsule endoscopy. it will reduce the completion rate of capsule endoscopy, and even lead to misdiagnosis and missed diagnosis. The purpose of this study is to explore the factors affecting the quality of gastroscopy gastric environmental preparation of magnetically capsule.
