| 4 | Screening and surveillance methods for dysplasia in inflammatory bowel disease patients:Where do we stand?显示文摘Patients with long-standing ulcerative colitis(UC) and extensive Crohn's colitis(CC) are at increased risk for dysplasia and colorectal cancer(CRC). Several studies have shown that UC extending proximal to the rectum, CC involving at least 1/3 of the colon, co-existence of primary sclerosing cholangitis, undetermined or unclassified colitis, family history of CRC and young age at diagnosis appear to be independent risk factors for inflammatory bowel disease(IBD)-related CRC. Therefore, screening and surveillance for CRC in IBD patients is highly recommended by international and national guidelines, whilst colonoscopy remains the unequivocal tool in order to detect potentially resectable dysplastic lesions or CRC at an early stage. Although the importance of screening and surveillance is widely proven, there is a controversy regarding the time of the first colonoscopy and the criteria of who should undergo surveillance. In addition, there are different recommendations among scientific societies concerning which endoscopic method is more efficient to detect dysplasia early, as well as the terminology for reporting visible lesions and the management of those lesions. This article concisely presents the main endoscopic methods and techniques performed for detecting dysplasia and CRC surveillance in patients with IBD focusing on their evidence-based accuracy and efficiency, as well as their cost-effectiveness. Finally, newer methods are mentioned, highlighting their applicability in daily endoscopic practice. | Michail Galanopoulos Emmanouela Tsoukali Filippos Gkeros Marina Vraka Georgios Karampekos Gerassimos J Matzaris | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，10： | 1 |
