E-Mail Knowledge in medicine is a very dynamic process due to the continuing progress in this field. New developments influence research, but also the clinical practice. Hence the continuous need for improvement in the field in which we work is required. Gastroenterology and hepatology, as part of internal medicine, are very dynamic fields of medicine, with numerous innovations, in the last 20-30 years at least. Starting with clinical medicine and continuing with endoscopy, interventional endoscopy or ultrasound and ending with precision medicine, with proteomics or metabolomics, the future of medicine seems to be here. The book 'What is New in Gastroenterology and Hepatology' aims to bring to the readers' attention the latest advances in gastroenterology and hepatology. The book offers a variety of topics in the field of gastroenterology and hepatology, approached in a structured, clear and comprehensive fashion, but also with practical applications.
