Endoscopy has revolutionised the practice of medical and surgical gastroenterology. The authors of this new edition, the leading endoscopists in the UK, aim to provide the newcomer to this field--or the practitioner requiring an update--with all the practical advice they need. In discussing the procedures themselves, the authors begin at the top of the gut and end at the bottom, digressing into the bile and pancreatic ducts along the way. As one reviewer has commented, the discussions throughout the text are characterized by the same "clarity of expression, perception of other endoscopists" difficulties and depth of their vast experience that is so evident when [the authors] are lecturing or teaching."
