Feedback survey on application of magnetically guided capsule endoscopy in diagnosis of upper gastrointestinal diseases

Abstract

Objective To evaluate the feasibility and acceptability of magnetically guided capsule endoscopy (MCE) as a screening or diagnostic means for upper gastrointestinal diseases. Methods One hundred and forty six patients underwent MCE during October 2013 to September 2014. All patients and endoscopists received a feedback survey with a self-administrated questionnaire; the items included the satisfaction of patients and endoscopists, the endoscopic image score, examination results, the endoscopy completion and operation time. Results Among 146 patients, 145 completed MCE examination with a completion rate of 99.3% (145/146). The operation time of MCE was(15.20±4.85)min. The score of patient and endoscopist satisfaction was both 4, and patient tolerance score was 0. The divergence rate score was 3; the cleaness score of stomach was 3; and the vision relative definition was 79.31±14.16. The most common examination result was chronic superficial gastritis (67/145, 46.2%), followed by bile reflex gastritis (48/145, 33.1%), normal stomach (39/145, 26.9%), gastric polyps (20/145, 13.8%), chronic atrophic gastritis (18/145, 12.4%), bleeding from erosive gastritis (14/145, 9.7%), reflux esophagitis (6/145, 4.1%), 2.7%(4/145), gastrointestinal ulcer, (3/145, 2.1%), upper gastrointestinal cancer (2/145), duodenal bulb inflammation (2/145), yellow melanoma (1/145), esophageal cyst (1/145) and esophageal varices (1/145). All patients expressed their willingness to receive the same type of upper GI endoscopy if necessary. No capsule retention, perforation or bleeding occurred. Conclusions MCE avoids the discomfort of conventional gastroscopy and can improve the compliance and acceptability of patients with excellent safety, maneuverability and feasibility.
