Bottom Line: This screening has resulted in long-term risk reduction in asymptomatic individuals.Image-enhanced endoscopies (IEEs), including the use of topical dyes, optical filtering, and ultramagnification, allow for gastrointestinal lesion analysis.IEE can be used to help the endoscopist to improve their ADR in screening colonoscopy.

ABSTRACT
Colorectal cancer (CRC) is a major cause of cancer mortality worldwide, and this has led to an increased use of screening colonoscopy. This screening has resulted in long-term risk reduction in asymptomatic individuals. However, endoscopists may fail to detect advanced adenomas or colon cancer during screening. The reasons that adenomas or cancers are missed are thought to be associated with the location of the lesions or the skills of the endoscopist. To address the limitations of white light endoscopy (WLE) for adenoma detection, advanced endoscopic images have recently been used. Image-enhanced endoscopies (IEEs), including the use of topical dyes, optical filtering, and ultramagnification, allow for gastrointestinal lesion analysis. Many studies have compared the adenoma detection rate (ADR) obtained by using WLE and IEE, but with different results. IEE can be used to help the endoscopist to improve their ADR in screening colonoscopy. This review examines the possible roles of image-enhanced colonoscopy in CRC screening.

Mentions: Indigo carmine is the most common dye used in image-enhanced endoscopy (IEE). CE with indigo carmine is a relatively classic procedure, but it is still one of the best procedures for evaluating lesions (Fig. 1). It is performed by using standard endoscopes. A diluted solution (0.1% to 0.4%) is sprayed onto the colonic mucosa by using a syringe via a spray catheter or the working channel of the endoscope.
