There have been significant developments in the fields of gastroenterology and hepatology since the previous edition and this new edition has been entirely revised, updated and considerably expanded. The format and layout have also been updated to include key points at the start of each chapter, bulleted lists and text boxes for tips and warnings. A new author team - which, for the first time, is international - has brought a new global perspective to this book. This is still the leading book for trainees/fellows in gastroenterology and hepatology, as well as junior doctors and general medicine interns. The series title is Pocket Consultant - and that's exactly what the reader gets - the advice and guidance of a consultant on hand when and where they need it.
