 SC(surveillance colonoscopy)in patients with UC(ulcerative colitis)should be performed at the time of assessment for endoscopic remission under medical management according to the treat-to-target strategy. LGD(low-grade dysplasia)is the preferred target of detection via SC for endoscopic resection and better prognosis. To detect LGD before the development of high-grade dysplasia or cancer, endoscopic procedures to enhance the contrast between neoplasia and nonneoplastic mucosae are logically suitable. SC via chromoendoscopy is useful for the endoscopic diagnosis of UC- associated neoplasia ; however, it is time-consuming. New evidence of narrow-band imaging for SC has recently been reported. More accurate and efficient SC techniques need to be developed.
