Mayo Clinic Gastroenterology and Hepatology Board Review, Sixth Edition, has been thoroughly revised to review the core essential knowledge in gastroenterology, hepatology, and relevant related areas of radiology, pathology, endoscopy, and nutrition for physicians, trainees, gastroenterology fellows in training, medical residents, medical students, gastrointestinal assistants, nurses, allied health care personnel, and other persons caring for patients.

This edition has been edited by a new team of Mayo Clinic gastroenterologists and hepatologists, under the stewardship of Dr. Stephen C. Hauser, the editor-in-chief of the previous fifth edition. The faculty who authored this edition are all Mayo Clinic physicians who spend their time caring for patients and teaching in an academic medical center. Accordingly, the emphasis of this edition is on clinical knowledge to enhance patient management. Case-based presentations and numerous board examination-type, single best-answer questions with annotated answers facilitate self-testing and studying.

· Features such as key facts and key definitions are included in each chapter
