Usefulness of Full-spectrum Endoscopy for the Upper Gastrointestinal Tract

Goals: We determined whether full-spectrum endoscopy (FUSE) improved the visualization rates of blind spots in a single-center case control study. Background: FUSE provides a 210-degree angle of view with a left side-viewing camera in addition to a forward-viewing camera. FUSE can improve the detectability of blind spots in conventional forward-viewing esophagogastroduodenoscopy (EGD), such as the major duodenal papilla (MDP) and the anal side of the pyloric ring. Study: Between April 2016 and May 2017, successful visualization rates of the whole MDP and anal side of the pyloric ring were compared between 103 participants who underwent FUSE and 1045 participants who underwent EGD. Pain and discomfort at insertion and during and after the examination were assessed using a visual analog scale in 38 participants who underwent FUSE with a previous examination history of EGD. Results: The successful visualization rates of MDP and the anal side of the pyloric ring in the FUSE group were significantly higher than those in the conventional EGD group; 83.4% versus 35.1% for MDP (P
