Efficacy and safety of magnetic guided capsule gastroscopy in gastric diseases.

The current mainstay of screening and diagnosis for gastric diseases is conventional standard gastroscopy. However, it is invasive and uncomfortable procedure for the patients especially in case of non-sedative procedures and other adverse effects related to conscious sedation anesthesia. Recently, a magnetic guided capsule gastroscopy (MGCG) was introduced to overcome these challenges. It is a safe and pleasant procedure with no involvement of sedation and no risks of cross-infection between patients. In addition, this method is anticipated to be an alternative tool for screening and diagnosis of gastric diseases with similar gastric visualization as one achieved through standard gastroscopy. In this narrative review, we focused on the recent advances in MGCG including technical issues, ideal gastric preparation, indications and contraindications, available evidences regarding the use of magnetic guided capsule gastroscopy in clinical practice and highlighted further technical advancements which are needed to make MGCG as a potential diagnostic tool. After reviewing the literature, we concluded that the magnetic guided capsule gastroscopy is a safe tool and would be a promising alternative examination equipment for gastric diseases.
