With the development and popularization of endoscopic technology and screening concept, the clinical application of magnetically controlled capsule gastroscopy (MCCG) is further highlighted. In recent years, various types of MCCG and optimization technology at home and abroad are widely used and developed rapidly. It is of great guiding significance to develop relevant guidelines. Based on clinical evidence, this guideline fully consulted experts′ opinions to make statements and recommendations on the aspects of definition and diagnostic accuracy, application population, technical optimization, inspection process and quality control of MCCG. It evaluates the quality of evidence and the strength of recommendation, and is expected to better guide the standardized application and scientific innovation of MCCG for the reference of clinical medical staff.
