Translated into seven languages, Cotton and Williams' Practical Gastrointestinal Endoscopy has for the last 25 years been the basic primer for endoscopy around the world, providing clear, clinical and practical guidance on the fundamentals of endoscopy practice, from patient positioning and safety, how to perform different endoscopic procedures, and the latest in therapeutic techniques and advances in technology.

It's key strength and reason for its popularity is its step-by-step, practical approach, especially with the use of outstanding colour artwork to illustrate the right and wrong ways to perform endoscopy. Add to this the weight and expertise of its author team, led by Peter Cotton and Christopher Williams, and the final result is an essential tool for all gastroenterologists and endoscopists, particularly trainees looking to improve their endoscopic technique.

Joining Peter Cotton, Christopher Williams and Brian Saunders in the seventh edition are two exciting stars in UK and US endoscopy, Adam Haycock and Jonathan Cohen. New to this edition are:

Approximately 35 high-quality videos illustrating optimum endoscopy practice, all referenced via “video eyes” in the text Self-assessment MCQs to test main learning points An online clinical photo imagebank to complement the line illustrations, perfect for downloading into scientific presentations Key learning points in every chapter Much more information on mucosal resection techniques and small bowel endoscopy—for capsule and “deep” enteroscopy The latest recommendations and guidelines from the ASGE, ASG, UEGW and BSG. Cotton and Williams' Practical Gastrointestinal Endoscopy, seventh edition is fully modernised, masterful as ever, and once again, the number one endoscopy manual for a whole new generation of gastroenterologists and endoscopists.
