The aim of this book is to provide them a strong foundation by familiarizing them with the basic concepts of endoscopy and aiding in correct interpretation of the pathology. Not withstanding the number of similar atlases available online, it is always quick and easy to refer to a printed copy that is lying in the endoscopist’s consultation chamber. Needless to say, printed images provide a longer lasting impression as compared to those seen on the computer screen. Effort has been made to replace some poor quality and repetitive images of the previous edition with new ones giving a fresh look to the current edition of the atlas. The atlas, in its current form, will find wide acceptance amongst the endoscopy practitioners.
