Colonoscopy is the bread and butter for endoscopists and advances in the procedure to reduce time, improve efficiency, and prevent errors are very important for this group. The newest advances look at colonoscopy efficiency and a better way to target tissue sampling, which avoids random biopsies and instead looks at ways to predict areas for sampling. The Guest Editors have selected top experts to provide these important updates and they also address current thinking that questions the continued value of colonoscopies as predictors of colon cancer. The issue will be a very popular one, and it needs to be heavily promoted.

In collaboration with Consulting Editor, Dr. Charles Lightdale, Dr. Douglas K. Rex has put together a state-of the-art issue of the Gastrointestinal Endoscopy Clinics of North America devoted to Colonoscopic Polypectomy. Expert authors have contributed clinical reviews that address best practices, evidentiary support, and expert recommendations. Articles specifically address the following topics: Endoscopic assessment prior to resection: What the experts do; Reviewing the evidence that polypectomy prevents cancer; The cold revolution: how far can it go?; Best methods for resection of diminutive and small polyps; Teaching polypectomy and assessing the quality of polypectomy; How to perform wide-field EMR and follow-up examinations; Surgery vs. EMR vs. ESD for large polyps: Making sense of when to use which approach; How to learn and perform ESD and full thickness endoscopic resection in the colorectum in the U.S; Underwater endoscopic mucosal resection (EMR); Lesion retrieval, lesions handling, marking; and Closure of defects and management of complications. Readers will come away with the latest information they need to evaluate options for lesion resection and to improve outcomes.

Together with Consulting Editor, Dr. Charles Lightdale, Dr. Doug Rex has put together an issue of Gastrointestinal Endoscopy Clinics that provides state-of-the-art clinical coverage of colorectal screening. Expert authors from all over the world have contributed clinical reviews that will be a staple for all practicing endoscopists. The articles are devoted to the following topics: What is organized screening and what is its value; Screening decisions in the opportunistic setting; �The National Colorectal Cancer Round Table: Past performance and current and future goals; Proven strategies for increasing screening adherence; Colorectal cancer in persons under age 50: Seeking causes and solutions; Risk stratification strategies: From logistic regression to artificial intelligence; �Cost-effectiveness of current screening tests; Quality in colorectal cancer screening; Screening for the serrated pathway; FIT: The world's colorectal cancer screening test; Fecal DNA testing: What has it accomplished and where is it headed; Is bowel preparation without complete colon clearing a viable concept: Update on flexible sigmoidoscopy, CTC, and capsule colonoscopy; Evidenced based screening strategies for a positive family history; Aspirational ADR and ideal colonoscopy performance: How long can we go between colonoscopies; and How Artificial Intelligence will impact colonoscopy and colorectal cancer screening. Readers will come away with the clinical knowledge they need to improve outcomes in colon cancer screening and prevention.

New edition of a leading reference on the field of colonoscopyWaye's Colonoscopy offers a comprehensive review of colonoscopy, covering insertion methods in routine and anatomically complex colon, endoscopic diagnosis of precancerous lesions, and all aspects of polyp resection. Many special aspects are reviewed including radiographic imaging of the colon, the pathology of colorectal polyps, pediatric colonoscopy, medical-legal risk in colonoscopy, and screening and surveillance for colorectal cancer. Key concepts are illustrated in colorful figures and many procedures are demonstrated by experts in videos accessible on a companion website.This Third Edition has been extensively updated and revised to cover major advancements in the field since the previous edition was published in 2009. These include developments in imaging that improve detection and characterization, artificial intelligence, the maturation of a worldwide movement to improve colonoscopy quality, the emergence of the cold revolution in resection, the enormous expansion of knowledge on wide field endoscopic mucosal resection, and the proliferation of endoscopic submucosal dissection.Written by a team of internationally recognized experts, Waye's Colonoscopy includes information on: General aspects of colonoscopy, including endoscopy room assistants, cleaning and disinfection processes, and green practicesPrinciples of electrosurgery in colonoscopy and management of antiplatelet agents and anticoagulantsOptical characterization of colonic neoplasia and techniques and devices for optimizing neoplasiaOvert cancer and covert cancerFull thickness resectionsApproaches to the unwell post-colonoscopy patient, and prevention and management of post-polypectomy bleeding and perforationWaye's Colonoscopy is an essential reference for practicing colonoscopists, gastroenterology fellows, surgical and colorectal surgery residents, and others in training to perform colonoscopy or wishing to improve their knowledge base and colonoscopy skills.
