Early detection and resection of neoplastic lesions are key objectives to diminish colorectal cancer mortality. Resection of superficialcolorectal neoplasms, cold snare polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection have all beendeveloped and used worldwide. The pocket-creation method facilitates the resection of tumors in diffcult and routine locations. Earlydetection is the most important first step to maximize the benefits of recent advancements in endoscopic techniques. However, thedetection of small, flat-shaped, or faded color lesions remains diffcult. Linked color imaging, a novel multi-light technology, facilitatesthe recognition of minor differences in tissue by enhancing the color contrast between early colorectal neoplasms and surroundingnormal mucosa in a bright field of view. The most striking feature of linked color imaging is its ability to display the color of earlyneoplastic lesions as distinct from inflammatory changes, both of which have similar “redness” when viewed using white light imaging. To increase the detection rate of neoplasms, linked color imaging should be used from the outset for endoscopic observation. Earlydetection of superficial colorectal tumors can result in decreased mortality from colorectal cancer and maintain a good quality of life forpatients.
Abstract
Early detection and resection of neoplastic lesions are key objectives to diminish colorectal cancer mortality. Resection of superficialcolorectal neoplasms, cold snare polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection have all beendeveloped and used worldwide. The pocket-creation method facilitates the resection of tumors in diffcult and routine locations. Earlydetection is the most important first step to maximize the benefits of recent advancements in endoscopic techniques. However, thedetection of small, flat-shaped, or faded color lesions remains diffcult. Linked color imaging, a novel multi-light technology, facilitatesthe recognition of minor differences in tissue by enhancing the color contrast between early colorectal neoplasms and surroundingnormal mucosa in a bright field of view. The most striking feature of linked color imaging is its ability to display the color of earlyneoplastic lesions as distinct from inflammatory changes, both of which have similar “redness” when viewed using white light imaging. To increase the detection rate of neoplasms, linked color imaging should be used from the outset for endoscopic observation. Earlydetection of superficial colorectal tumors can result in decreased mortality from colorectal cancer and maintain a good quality of life forpatients.
