Abstract

AIM: To evaluate the full-spectrum endoscopy (FUSE) colonoscopy system as the first report on the utility thereof in a Korean population.

METHODS: We explored the efficacy of the FUSE colonoscopy in a retrospective, single-center feasibility study performed between February 1 and July 20, 2015. A total of 262 subjects (age range: 22-80) underwent the FUSE colonoscopy for colorectal cancer screening, polyp surveillance, or diagnostic evaluation. The cecal intubation success rate, the polyp detection rate (PDR), the adenoma detection rate (ADR), and the diverticulum detection rate (DDR), were calculated. Also, the success rates of therapeutic interventions were evaluated with biopsy confirmation.

RESULTS: All patients completed the study and the success rates of cecal and terminal ileal intubation were 100% with the FUSE colonoscope; we found 313 polyps in 142 patients and 173 adenomas in 95. The overall PDR, ADR and DDR were 54.2%, 36.3%, and 25.2%, respectively, and were higher in males, and increased with age. The endoscopists and nurses involved considered that the full-spectrum colonoscope improved navigation and orientation within the colon. No colonoscopy was aborted because of colonoscope malfunction.

CONCLUSION: The FUSE colonoscopy yielded a higher PDR, ADR, DDR than did traditional colonoscopy, without therapeutic failure or complications, showing feasible, effective, and safe in this first Korean trial.

Keywords: Colonoscopy, Colonoscopes, Feasibility studies, Colonic polyps

Core tip: Although many efforts have been made to improve visualization and reduce blind spots in the colonic mucosa, about 10% of the colonic surface remains unobserved during traditional standard forward-view (SFV) colonoscopy. In contrast to the maximum field of view (170°) of SFV colonoscopes, the full-spectrum endoscopy (FUSE) colonoscopy platform affords the endoscopist a high-resolution, 330°“full spectrum” view of the colorectal mucosa. In this first Korean trial, the FUSE colonoscopy yielded a higher polyp, adenoma, diverticulum detection rate without therapeutic failure or complications, to be feasible, effective, and safe.
