BACKGROUND AND STUDY AIMS: Optimizing polyp detection, in particular the right-sided colon polyps, is a challenge for endoscopists. This study aimed to evaluate the diagnostic value of LCI combined with CAD EYE in the detection and characterization of right-sided colon polyps.
PATIENTS AND METHODS: Patients underwent colonoscopy with WLI up to the cecum and terminal ileum, followed by LCI combined with CAD EYE. All polyps detected were removed and subjected to histological examination.
RESULTS: 116 patients were enrolled. Out of them, 66 patients had at least one polyp in their right-sided colon. Endoscopy utilizing LCI resulted in a significantly high additional polyp detection rate (APDR) of 25.9 % (95 % CI: 17.6-36.4 %) in the right colon compared to endoscopy with WLI. The APDRs were significantly higher for flat polyps, 43.5 % (95 % CI: 25.6-63.2 %), p = 0.023. The adenoma detection rate (ADR) was also increased, with APDRs for adenomatous polyps and sessile serrated polyps at 30.6 % (95 % CI: 18.0-46.9 %) and 66.7 % (95 % CI: 30-90.3 %), respectively (p = 0.022). The concordance in neoplasia detection utilizing LCI combined with CAD EYE and histological examination demonstrated substantial agreement between the two approaches, with Kappa values of 0.729 (p < 0.001).
CONCLUSION: LCI combined with CAD EYE emerged as a potential tool for characterizing right-sided colon polyps.
