Digestive diseases have always been a major threat to global health. Despite the rapid advances in various diagnostic modalities, many a time the final verdict can be elusive and present a diagnostic challenge for the attending doctor. Clinical Challenges & Images in Gastroenterology — A Diagnostic Guide presents 50 real-life cases to illustrate an evidence-based approach for the diagnosis, investigation, and management of gastrointestinal diseases commonly encountered in everyday practice, with a special focus on the interpretation of endoscopic and radiological images. This book provides a pragmatic approach for medical students, residents, specialist trainees, and specialists alike who have an interest in gastroenterology. Other healthcare providers, such as general practitioners, nurses, and dieticians, will also benefit from these case illustrations. The authors of this book are based at the Institute of Digestive Disease, Chinese University of Hong Kong.
