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. An updated and improved 3rd edition was published in French in 2020; this translation and update make the book available in English for the first time. The text features contributions from GI experts from Quebec, France, French Africa, and from key Canadian GI experts. The first part of the book covers the eight main organs of the digestive system, while the second half discusses the major clinical diseases and symptoms that affect the digestive system. 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 students.
