[The China expert consensus of clinical practice for magnetically controlled capsule gastroscopy(2017, Shanghai)].

Gastric diseases are very common in China, especially gastric cancer with a continuous high level of morbidity and mortality. As an important screening method of gastric diseases, magnetically-controlled-capsule-gastroscopy (MCCG) has already been widely used in medical institutions worldwide. Several clinical trials have already showed that MCCG has comparable accuracy in diagnosing gastric diseases compared with conventional gastroscopy. Furthermore, MCCG has the advantages of anesthesia free, no risks of cross infection, and excellent compliance. Thus MCCG could be a potential alternative technique of conventional gastroscopy. Based on the clinical practice of MCCG during recent years, Chinese doctors have gained a lot of experience. In order to standardize and popularize the application of MCCG, the expert consensus for the clinical application of MCCG was developed through several discussions and modifications among Chinese experts in the field of capsule endoscopy.
