Background and Aims: Capsule endoscopy is a valuable tool in the diagnosis of small bowel disease. However, the incompletion of small bowel examination may reduce the diagnostic accuracy, which mainly caused by delayed capsule gastric emptying. Thus the aim of this study was to validate the effect of magnetic steering on enhancing gastric emptying and mucosal visualization within duodenum during magnetically controlled capsule gastroscopy (MCCG) examination.~Methods: As a historical prospective cohort study, the research continuously enrolled 100 patients undergone MCCG between May to December 2017 as the intervention group with magnetic steering of capsule in the pylorus and duodenum, and randomly selected 100 patients before May 2017 from the database as the control group with passive movement of the capsule. The difference of the pyloric transit time (PTT) and duodenal papilla detection rate (DPDR) between the two groups were compared, and related factors were also investigated.
