Endoscopy is a fast moving field, and new techniques are constantly emerging. Flexible endos‐ copy became the principal investigational tool of the pathological abnormalities with great im‐ pact on modern medicine. In recent decades, endoscopy has evolved and branched out from a visual diagnostic modality, to enhanced video and computer assisted imaging, with impressive interventional capabilities. Some new endoscopic techniques will be too complex or expensive to make the leap into general practice, others already show major progress in the management of diseases. Modern endoscopy has seen advances not only in the types of endoscopes availa‐ ble, but also the types of interventions amenable to the endoscopic approach. As in any field, demands of service delivery by conventional equipment and newer, more glamorous, and usu‐

Modern endoscopic equipment provides us with the benefit of many technical advances. New video-endoscopes, magnification endoscopes and confocal of narrow band imaging endoscopes emerged. An increased knowledge of normal and pathologic endoscopic patterns has been in‐ creasing in the last decades. Endoscopy is an effective and safe procedure even in special popu‐ lations including pediatric patients, pregnant patients and liver transplant patients. It served as the tool for diagnosis and therapeutic interventions of many organs including gastrointestinal tract, head and neck, respiratory tract and others. In this book the authors will discuss some of the emerging techniques and technologies used to increase the diagnostic and therapeutic yield

The contributions in this book are very valuable. InTech Open Access Publisher selected several known names from many countries with different levels of development. Multiple specific points of view were presented together with various topics regarding diagnostic or therapeutic endoscopy. The readers can take into consideration of practical knowledge in the endoscopic field. This book actually represents a valuable tool for formation and continuous medical edu‐ cation in the endoscopy considering the performances or technical possibilities in different
