All participants were instructed to swallow the CT-MCCE capsule. An external magnetic robot arm was utilized to manipulate the capsule endoscope with string-facilitated control of the endoscope. This study assessed gastric preparation, safety, maneuverability, and mucosal visualization.Results: The participants exhibited favorable reactions to the gastric preparation and examination, with no reported adverse effects, and the average duration of the gastric examination was 29.5±6.63 minutes. The gastric cavity cleanliness assessment revealed a good rating in 25 participants (83.3%) and a moderate rating in 5 participants (11.8%). TheCT-MCCE demonstrated good maneuverability in all 30 subjects (100%).The analysis of visualization indicated that more than 75% of the gastric mucosa was discerned in 79.4% of the participants (27 individuals), whereas 50% to 75% was visualized in 20.6% of the participants (7 individuals).Conclusion: This study substantiates the feasibility and safety of employing magnetically controlled capsule endoscopy with cable transmission for the evaluation of human stomach and esophagus.
