This textbook on the digestive system was developed in collaboration with medical students to meet both students' and teachers' needs and objectives. It is currently the official gastroenterology textbook for undergraduate students in all French medical schools in Canada, and is also used in Europe and Africa. This update represents the second edition of the English language text. The text features contributions from GI experts from Quebec, France, French Africa, and from key Canadian GI experts.

The organization of the book has been updated. The text is now organized into eight parts, with each devoted to a specific digestive organ. Each part will contain a fully updated overview of the organ and then chapters detailing the relevant symptoms, signs, and diseases for that organ. This book is comprehensive and well-organized, and features color-coded and beautifully designed figures and tables that make the book helpful and accessible to trainees and students.
