A case of screening colonoscopy using linked-color imaging to detect ulcerative colitis–associated colorectal cancer

Abstract

The long-term course of ulcerative colitis (UC) is characterized by an increasing incidence of UC-associated colorectal cancer (UCAC). Although the standard method for detecting UCAC is dye-based chromoendoscopy, it has recently reported that dye-based and dye-less chromoendoscopy do not differ significantly in terms of detection of UCAC [1]. Linked-color imaging (LCI) is a new endoscopic technique that can enhance color differences in the gastrointestinal mucosa by simultaneously using white light and narrow-band, short-wavelength light.
