We are pleased that the third edition of Current Diagnosis & Treatment: Gastroenterology, Hepatology, & Endoscopyhas been published within three years of the publication of the second edition. The editors felt this timetable was especially important in order to provide up-to-date information on a number of topics in which there is rapidly accumulating information, especially with regard to therapeutic considerations. Disorders in which there have been noteworthy advances in diagnosis and therapeutics include, but are not limited to, Barrett esophagus, eosinophilic esophagitis, esophageal motility disorders, inflammatory bowel disease, acute pancreatitis (revised Atlanta Guidelines), autoimmune pancreatitis, chronic hepatitis B, chronic hepatitis C (there is now an effective treatment), and nonalcoholic fatty liver disease.

A new chapter on gastrointestinal manifestations of mast cell disorders provides an important update on this increasingly recognized disorder. The references have been updated to include pertinent articles published in 2014. We have been particularly interested in incorporating important advances in therapeutics in many of the sections in the textbook. We especially want to thank Mr. Clayton R. Bemis for his fine efforts in incorporating the many changes submitted by the authors into the final revisions.
