Rather than describing the general endoscopic treatment of biliary-pancreatic disease, this book focuses on the role of high-end (advanced and extreme) ERCP procedures in biliary and pancreatic diseases that are difficult to treat. Readers will find clear descriptions of innovative endoscopic techniques and the therapeutic endoscopy management solutions currently available for these diseases. It is anticipated that the described procedures will continue to be applied in clinical practice even if other procedures are developed in the future. The book will accordingly be of enduring value for all endoscopists who specialize in biliary-pancreatic disease, from beginners to experts. The precise explanations of treatment concepts and strategies will both increase readers’ knowledge and provide assistance in daily clinical practice. The authors are pioneering experts from around the world, and the text is supported by numerous informative illustrations and helpful summaries.
