Summary: "The world has turned upside down since the last edition of this textbook was published in 2016. The COVID-19 pandemic and its resultant need for social distancing has changed the manner in which we practice medicine with televisits now often being substituted for in-person visits. As uncomfortable as that has become for many clinicians, one outgrowth has been the need to emphasize once again the importance of the patient's history rather than relying on imaging and invasive testing that may be more difficult to arrange. The role of a central compendium of knowledge of pediatric gastrointestinal, hepatic, and nutritional disorders has never been more important. Having such a resource at the clinician's fingertips should facilitate a more directed and focused problem-based approach. That was our goal 27 years ago with the publication of the first edition of this textbook, and it remains our goal now. For novices to the field as well as for experienced clinicians, it is invaluable to have a primary resource even in this age of instant electronic searches. As powerful as today's search engines are, they cannot substitute for a well-written comprehensive textbook."--Preface.
