AIM:To determine the performance of novice readers(4~(th)year medical students)for detecting capsule endoscopyfindings.METHODS:Ten capsule endoscopy cases of small bowellesions were administered to the readers.Gold standardfindings were pre-defined by gastroenterologists.Tengold standard“targets”were identified among the 10cases.Readers were given a 30-min overview of RapidReader software and instructed to mark any potentialareas of abnormalities.A software program wasdeveloped using SAS to analyze the thumbnailed findings.RESULTS:The overall sensitivity for detecting the goldstandard findings was 80%.As a group,at least 5 outof 10 readers detected each gold standard finding perrecording.All the gold standard targets were identifiedwhen the readers’results were combined.Incidentalfinding/false positive rate ranged between 8.2-59.8 perreader.CONCLUSION:A panel of medical students withminimal endoscopic experience can achieve high sensitivity in detecting lesions on capsule endoscopy.A group of novice readers can pre-screen recordingsto thumbnail potential areas of small bowel lesions forfurther review.These thumbnails must be reviewed todetermine the clinical relevance.Further studies areongoing to assess other cohorts.
