    Objective To investigate the diagnostic ability of magnetically controlled capsule gastroscopy(MCGE)for the detection of upper gastrointestinal(GI)lesions in asymptomatic individuals with different characteristics.Methods Cinical data of 168 asymptomatic subjects who received MCGE examination in digestive endoscopy center of our hospital were retrospectively collected and analyzed.The detection status of upper GI lesions,the tolerance and safety of the subjects were statistically analyzed,and the detection rate of lesions among the people with different characteristics were compared.Results In 168 subjects,there were 104 males and 64 females.Seventy-eight cases were ≤45 years old and 90 cases were45 years old.There were 138 cases of simple physical examination and 30 cases with special reasons.The total detection rate was 44.6%.The detection rates of bile reflux,erosive g astritis,gastric polyp were8%.The detection rates of erosive esophagitis,stomach apophysis lesions,gastric ulcer were 3% ~5%.The detection rates of lower esophagus island orange mucosa and esophagus protuberant focus,gastric yellow pigment tumor,small intestine stomach ulcer and intestinal vascular malformation were2%.The overall abnormal detection rate of male subjects was significantly higher than that of female subjects(51.9% vs.32.8%,P=0.016),mainly with erosive gastritis.The overall abnormal detection rate of45 years old cases was significantly higher than that of≤45 years old cases(54.4% vs.33.3%,P=0.006).There was no sigrnificant difference in the overall abnormal detection rate between the simple physical examination group and the special cause group(42.8% vs.53.3%, =0.291).No capsules were retained in all subjects.Conclusion MCGE is safe and tolerable,with a higher detection rate of lesions in male and45 years old subjects,providing a basis for clinical selection of subjects and evaluation of examination results.
