Preliminary Experience Using Full-Spectrum Endoscopy for Colorectal Cancer Screening: Matched Case Controlled Study

Abstract

<i>Background/Aim</i>. High-quality colonoscopy is needed to reduce the morbidity and mortality of colorectal cancer. Full-spectrum endoscopy (FUSE) has recently shown potential in improving adenoma detection during colonoscopy. This study aimed to evaluate the feasibility and utility of FUSE colonoscopy. <i>Methods</i>. From April 2015 to February 2016, 130 patients underwent FUSE colonoscopy for screening at a tertiary cancer center. Cecal intubation rate (CIR), procedure time, polyp/adenoma detection rate (PDR/ADR), and mean number of adenomas per colonoscopy (APC) were compared in matched-control patients (<i>n</i> = 260) who underwent standard colonoscopy (SC). Accordingly, endoscopists subjectively evaluated the utility of FUSE colonoscopy. <i>Results</i>. The CIR of FUSE colonoscopy was 94.6%. Cecal intubation time (8.8 min versus 5.1 min, <i>P</i> < 0.001) and total procedure time (21.6 min versus 17.3 min, <i>P</i> < 0.001) in the FUSE group were significantly longer than those in the SC group. PDR (68.3 versus 71.2%, <i>P</i> = 0.567), ADR (63.4% versus 58.5%, <i>P</i> = 0.355), and APC (1.4 versus 1.4, <i>P</i> = 0.917) were not significantly different between the two groups. The wide view of FUSE colonoscopy was superior to that of SC based on the questionnaires. <i>Conclusions</i>. FUSE colonoscopy did not demonstrate superiority to SC in a clinical setting.
