Advanced endoscopic technologies for detection of colorectal neoplasms

Colonoscopy has been established as the gold standard for the detection of colorectal neoplasms. Adenoma detection rate (ADR) is one of the most important quality indicator of colonoscopy, and, as it has been recommended by a European Society of Gastrointestinal Endoscopy (ESGE), the benchmark for ADR is 20%. However, ADR widely varies, and almost one fourth of polyps and adenomas are missed. Currently several techniques have been developed with the aim to improve the quality of colonoscopy. Among them there are image-enhanced endoscopy (IEE) and techniques or devices that improve mucosal observation. IEE includes chromoendoscopy and virtual chromoendoscopy (NBI, FICE, AFI, i-scan); among techniques which enable better observation of the mucosa there are add-on devices, such as transparent cap, Endocuff, Endocuff Vision, Endorings; and wide-angle colonoscopes (full spectrum endocopy - FUSE). In the literature review, these mentioned techniques and their effect on ADR are described.
