Abstract
In the past 20 years, several magnetically controlled capsule endoscopes (MCCE) have been developed for the evaluation of gastric lesions, including NaviCam (ANKON), MiroCam-Navi (Intromedic), Endocapsule MGCE (Olympus and Siemens), SMCE (JIFU), and FAMCE (Jinshan). Although limited to observing esophageal and duodenal lesions and lacking the ability of biopsy, MCCE has the advantages of comfort, safety, no anesthesia, no risk of cross-infection, and high acceptability. Several high-quality RCTs showed that the diagnostic accuracy of MCCE is comparable to the traditional gastroscopy. Due to the nonnecessity of anesthesia, MCCE may be more suitable for the elderly with obvious comorbidities as well as children. With more evidences accumulated and more innovative technologies developed, MCCE is expected to be an important tool for screening of early gastric cancer or the diagnosis of gastric diseases.
Highlights
Gastric diseases, including gastritis, gastric ulcer, and gastric cancer, are common in the general population, which seriously threaten human health and cause a huge economic burden
Magnetically controlled capsule endoscopy has certain diagnostic capabilities and minimal invasiveness and can be applied to the examination of gastric diseases, which will be beneficial to the general screening of gastric cancer in large-scale populations
A number of studies have proven that the accuracy of the magnetically controlled capsule endoscopy for the diagnosis of gastric diseases is highly consistent with that of traditional gastroscopy
Summary
Gastric diseases, including gastritis, gastric ulcer, and gastric cancer, are common in the general population, which seriously threaten human health and cause a huge economic burden. A simpler and less invasive inspection method is needed as an Gastroenterology Research and Practice alternative to traditional gastroscopy to increase the rate of early diagnosis and treatment of gastric diseases in the population. Since its birth in 2000 [11], capsule endoscopy has been widely used in the diagnosis and treatment of small intestinal diseases, such as small intestinal bleeding, Crohn’s disease, small intestinal malignant tumors, and small intestinal mucosal lesions associated with nonsteroidal anti-inflammatory drugs [12]. It is a routine technique carried out by digestive endoscopists. The prospects for future development of MCCE are discussed
