Detection of Nonpolypoid Colorectal Neoplasia Using Magnifying Endoscopy in Colonic Inflammatory Bowel Disease

説明

Patients with inflammatory bowel diseases (IBD) have a high risk of colitis-associated dysplasia and cancer. It is important that careful surveillance with colonoscopy is performed for all patients with IBD and, more frequently, for those considered to be at high risk. Traditionally, flat dysplasia in ulcerative colitis has been considered to be detectable only by using random biopsy specimens of mucosa that appeared unremarkable during endoscopy. However, recent studies have shown that most of them are visible; thus, their detection as nonpolypoid colorectal neoplasms is an integral component in the prevention of colitic cancer.
