This comprehensive book features high-quality images, videos, and step-by-step instructions for capturing detailed views of the upper and lower gastrointestinal tract from the oral cavity to the anus. In addition to covering areas such as the tongue, head and neck, non-Barrett’s esophagus, Barrett’s esophagus, stomach, duodenum, colon, and rectum, the atlas is authored by leading GI experts from the Asian Novel Bio-Imaging and Intervention Group in the Asia-Pacific region, known for their unparalleled expertise and commitment to excellence.

The book covers various aspects, including equipment reviews and diagnostic technologies using the latest unified global standard system. It explains techniques such as high-definition endoscopy, magnifying endoscopy, chromoendoscopy, NBI, TXI, RDI, and AI, while also providing insight into classifications such as the Japan Esophageal Society Classification, the VS Classification/MESDA-G, and the JNET Classification. Each case section provides expert analysis and notable endoscopic images, accompanied by histopathologic images depicting various benign lesions and early cancers.

The Atlas of Advanced Endoscopy serves as an invaluable resource to enhance the reader’s knowledge and understanding of the complexities of gastrointestinal endoscopy. It is designed to help practitioners, clinicians, gastroenterologists, and medical students learn diagnostic strategies, procedures, and clinically significant cases. We hope this atlas will always be at your side in the endoscopy room.
