The open-access book Hepatobiliary Medicine and Surgery - Gallbladder is intended for surgeons, physicians, radiologists, nurses, researchers, scientists, educators, and other healthcare professionals interested in gallbladder diseases and surgery, both in specific and broad terms. The book comprises seven chapters and features eight distinctive characteristics that contribute to its originality. Richly illustrated with numerous original figures, it covers the etymology of specific terms and utilises Latin terms to emphasise the roots of modern medicine and medical ethics. It highlights the connection between anatomical details and surgical actions in a new way. The book outlines new hepatobiliary disease and surgery concepts, and it systematically presents the ultrasonographic features of intramural and extramural gallbladder wall thickening. It also highlights other fundamental aspects, such as emphasising the classification of cholecystectomies in the context of a safety-first culture in gallbladder surgery. Other details related to the anatomy, physiology, and pathology of the gallbladder that healthcare professionals less commonly address in forums and scientific literature are a distinct feature of this book.
