Image-enhanced endoscopy is critical in the detection, diagnosis, and treatment of non-polypoid colorectal neoplasms

Colonoscopy, the most sensitive test used to detect advanced adenoma and cancer, has been shown to prevent colorectal cancer (CRC) when combined with polypectomy. CRC remains the third most commonly diagnosed cancer and the second leading cause of cancer death in men and women in the United States. Image-enhanced endoscopy (IEE) is an integral part in the detection, diagnosis, and treatment of non-polypoid colorectal neoplasms. Both the dye-based and equipment-based varieties of IEE are readily available for application in today's practice of colonoscopy. Data are available to support its use, although further studies are needed to simplify the classification of colorectal lesions by the different techniques of equipment-based IEE.
