Pancreatology, as a discipline, has not been in focus for long has become a vanishing specialty for a variety of reasons. As a consequence, pancreatologists face several issues despite the ongoing their e orts in managing their practice and maintaining their identity in the fraternity. e changes in medical practice in many parts of the world have led to a shift of responsibilities, away from the surgeon and towards the gastroenterologist. e latter may not be equipped with su cient resources to acquire the knowledge. While the mainstream issues in pancreatology are taught at various levels and conferences, as well as guidelines, the remaining is mostly left to the experts, not to say connoisseurs. A selection of such experts from around the globe have contributed to this book with very special cases and exemplifying problems in the form of case reports for better application and understanding of the same in clinical practice. Medical journals in the hunt for their respective impact factors have stopped publishing case reports as these cannot be cited, therefore other channels become imperative to impart this knowledge to the medical community. Puzzling Cases in Pancreatic Diseases is a logical initiative in this direction. A good deal can be learned from these case reports that are professionally presented and discussed.
