“…However, in screening patients, no benefit could be seen [103]. Extra-Wide-Angle-View colonoscopes (Olympus, Tokyo, Japan) using 170° in combination with HDTV might improve the ADR as seen in a German prospective study by Adler et al [104] with 22% increase in the ADR.…”

Background: The presence of colorectal adenomas is considered a major risk factor for colorectal cancer development. The implementation of screening colonoscopy programs in the Western world has led to a substantial reduction of colorectal cancer death. Many efforts have been made to reduce the adenoma miss rates by the application of new endoscopic devices and techniques for better adenoma visualization. Summary: This special review gives the readership an overview of current endoscopic innovations that can aid in the increase of the adenoma detection rate (ADR) during colonoscopy. These innovations include the use of devices like EndoCuff® and EndoRings® as well as new technical equipment like third-eye endoscope® and full-spectrum endoscopy (FUSE®). Key Message: Technical improvements and newly developed accessories are able to improve the ADR. However, additional costs and a willingness to invest into potentially expensive equipment might be necessary. Investigator-dependent skills remain the backbone in the ADR detection.

In order for screening colonoscopy to be an effective tool in reducing colon cancer incidence, exams must be performed in a high-quality manner. Quality metrics have been presented by gastroenterology societies and now include higher adenoma detection rate targets than in the past. In many cases, the quality of colonoscopy can often be improved with simple low-cost interventions such as improved procedure technique, implementing split-dose bowel prep, and monitoring individuals' performances. Emerging technology has expanded our field of view and image quality during colonoscopy. We will critically review several technological advances in the context of quality metrics and discuss if technology can really improve the quality of colonoscopy.

“…The newest-generation endoscopes provide both a moderate wide-angle view (170°) and high resolution. A comparison of such colonoscopes with the former-generation standard colonoscopes increased rates of adenoma detection by 22% [27]. However, it remains unclear whether the crucial factor is high definition or wide angle.…”

Colorectal cancer represents one of the leading malignancies worldwide. Early endoscopic detection and removal of its precursor lesions, adenomas, and serrated hyperplastic polyps results in a decrease of colon cancer-related death. However, miss rates in adenoma detection up to 26% underline the need for high compliance to basic measures and further improvement in methodology and technology. Basic parameters affecting adenoma detection rates include sufficient training and awareness of the endoscopist, use of high-definition endoscopes, careful examination behind folds, cleansing the colon wall, accurate distention of the colon, and adequate withdrawal time. Advanced imaging techniques, introduced to further improve adenoma detection, have yielded mixed results. These include wide-angle colonoscopes, cap-assisted colonoscopy, and retroscopic methods which may add new obstacles to colonoscopy. Moreover, chromoendoscopy either ‘virtual’ or by topically applied dyes has been suggested to enhance the detection of colonic neoplasia. Yet, studies on patients with average cancer risk have failed to reproduce promising initial results. Similarly, although autofluorescence has not enhanced the diagnostic yield in screening a population at average risk, it may be useful in patients at increased cancer risk. Recently, technical feasibility of molecular imaging employing ‘biomarkers’ has been demonstrated, but needs further evaluation. The newest developments, employing light-scattering spectroscopy, suggest the existence of a ‘field effect’ of colonic carcinogenesis and may enable detection of the earliest neoplastic events and distant adenomas even when applied to normal-appearing mucosa. Upon confirmation, these technologies may result in a substantial change in patient management and risk stratification.
