Colonoscopy Atlas of Colon Polyps and Neoplasms

Optical colonoscopy is the gold standard for colon cancer screening and adenoma detection and is the only screening option that can potentially provide therapeutic interventions and adenoma removal during the same session. When other screening strategies generate positive results, currently colonoscopy is the next step for definitive diagnosis and potentially curative therapy. For gastrointestinal endoscopists, the ileocecum is the finishing line during colonoscopy, and it is identified by three endoscopic landmarks: terminal ileum, ileocecal valve, and the appendiceal orifice. Careful and systematic examination should be stressed during endoscopic training and practice. In this pictorial review, the authors demonstrate common colon polyps and neoplasms that can be found during colonoscopy. Our aim is to educate gastroenterologists, endoscopy staff other health care providers, and interested patients on certain colon pathologies and common endoscopic interventions.
