“…[42][43][44][45] These analyses affirm the Cochrane review, demonstrating no significant difference between HD-NBI and HD-WLE in the detection of adenomas and polyps. One of these meta-analyses additionally compared polyp miss rates between HD-NBI and HD-WLE.…”

“…Six meta-analyses assessed the ADR of the NBI system compared with that of white-light colonoscopy (WLI). [24][25][26][27][28] None of them found any difference in adenoma, small adenoma (<10 mm) or diminutive adenoma (<5 mm) detection rates. Another meta-analysis revealed a sensitivity comparing with Lucera and Exera II systems (Olympus Medical Systems).…”

Colonoscopy is considered the best modality for the detection and treatment of colorectal polyps. However, some polyps still may not be detected. Although conventional white‐light endoscopy is the gold standard for the detection of colorectal polyps, up to a fifth of lesions may be missed on screening colonoscopy, especially non‐polypoid colorectal neoplasms. Recently, many studies have reported on various endoscopic modalities that improve the detection and characterization of colorectal lesions. Newly developed modalities might be helpful to recognize colorectal lesions; however, careful observation is required to identify flat/depressed lesions as well as hidden polyps during screening and surveillance colonoscopy.

“…Even so, a lower miss rate for adenoma in the proximal colon was achieved by performing NBI colonoscopy [10], while the detection rate of flat adenomas has increased with NBI [11]. Recent meta-analyses and systematic reviews have also shown that NBI provides no increase in adenoma or polyp detection rates compared with conventional colonoscopy [12,13]. However, after exclusion of high-definition television modalities, the rate of adenomas detection by NBI compared with white light was significantly higher, especially in patients with one adenoma.…”

“…However, after exclusion of high-definition television modalities, the rate of adenomas detection by NBI compared with white light was significantly higher, especially in patients with one adenoma. The detection of flat adenoma has also increased using NBI colonoscopy [13]. Due to conflicting data from published trials, the potential benefit of NBI technique in neoplastic colonic lesions detection, especially in right-sided lesions and flat adenoma, requires further evaluation.…”

Narrow band imaging represents a promising endoscopic technique which allows real time characterization of colonic lesions by assessment of mucosal and vascular patterns. Due to the ability to make an optical biopsy, NBI could become a useful tool in clinical decisions regarding therapy and surveillance. The aim of this paper is to review the current knowledge on the optical diagnosis of colonic lesions by using NBI endoscopy. We reviewed research articles, reviews and meta-analyses from the PubMed and MEDLINE containing relevant data in this field. The validity of endoscopic criteria for the differentiation of adenoma and hyperplastic polyps, as well as of invasive cancer, has been evaluated in recent studies. Based on the prediction of polyp histology, new potential cost saving strategies have been proposed. Many reports are focused on the accuracy of optical biopsy by using NBI for predicting colonoscopy surveillance intervals and adenomatous histology in diminutive polyps, according to the Preservation and Incorporation of Valuable Endoscopic Innovations statement. Optical diagnosis is still under evaluation, and cannot yet be endorsed in routine practice. The high level of performance achieved by expert endoscopists needs to be replicated in the community utilizing reliable and standardized endoscopic criteria. IntroductionThe development of advanced endoscopic techniques such as narrow band imaging endoscopy, with or without magnification, represents an important step in the improvement of characterization of colonic lesions by predicting underlying histology. This creates the possibility to adopt new strategies regarding therapy and surveillance in clinical practice. The potential benefits of the real time estimation of a polyp's histology during NBI endoscopy, so called "optical biopsy", are related to potentially decreasing total costs of colonoscopy by eliminating unnecessary biopsies and polypectomies. Recent reports have shown promising results in this field, but controversies remain. Concerns center upon a lack of standardization among different classification systems, variable inter-observer agreement, and lagging clinical acceptance.The aim of this paper is to assess the current knowledge on the optical diagnosis of colonic lesions by using NBI endoscopy. We reviewed research articles, reviews and meta-analyses published in the last eight years in the PubMed and MEDLINE databases for the following search terms: narrow band imaging endoscopy, colonic polyps, and colorectal neoplasia.
