Abstract
Objective To investigate the clinical application value of magnetically guided capsule endoscopy (MGCE) to stomach examination. Methods Data of 500 patients who received MGCE examination from January 2014 to February 2016 in our hospital were retrospectively analyzed. The feasibility and safety of MGCE were studied by analyzing the detection rate of gastric lesions, transit time, adverse events, clarity and visibility, in comparison with esophagogastroduodenoscopy(EGD). Results The lesion detecting rate was 57.8%(289/500), the average transit time was (106.0±101.1)min. Overall effective rate of cleanliness was 91.8%. The visibility satisfaction rate was 98.8%. Compared with EGD, MGCE had good detection ability in stomach focal lesions. The sensitivity, specificity and accuracy were 92.0%, 85.7% and 88.3%, respectively. Except for capsule retention occurred in one patient, no other complication happened. Conclusion MGCE, stable and safe, shows high detection and accuracy rates for gastric diseases, and can be used as an effective examination tool.
