Study Objective: to assess the results of narrow spectrum endoscopy using the Narrow-band Imaging International Colorectal Endoscopic Classification in diagnostics of small colorectal epithelium tumours in an oncological hospital.

Study Design: comparative prospective study.

Materials and Methods. 84 patients with 149 colorectal polyps of max. 10 mm were examined in the Endoscopy Unit of Yaroslavl Regional Clinical Oncological Hospital. Endoscopy and histopathology results were compared.

Study Results. Narrow spectrum endoscopy sensitivity for differentiation of hyperplastic and adenomatous polyps was 84.6% (95% CI 78.35–89.58%), specificity — 99.2% (95% CI 95.5–99.9%), favourable prognostic significance — 99.3% (95% CI 96.3–99.9%), negative prognostic significance — 81.9% (95% CI 74.7–87.7%). In ROC analysis, the area under ROC curve was 0.92 (95% CI 0.88–0.95). The statistical significance of probability/ relative predictive risk ratio (i.e. coincidence between the proposed diagnosis and morphological findings) made р = 0.0007 and р < 0.0001, respectively.

Conclusion. Narrow spectrum endoscopy is highly efficient in differentiation of hyperplastic and adenomatous colorectal polyps of max. 10 mm. The most significant results were obtained for polyps of less than 6mm located in rectum and sigmoid colon.
