Crohn's disease (CD) is a subtype of inflammatory bowel disease (IBD) that can affect any part of the intestine and can lead to stricture, fistula, and abscess if left untreated. This book highlights the key aspects of the current state of the art of pathogenesis, diagnosis, and therapy for CD and its unique complications. CD has evolved from clinical observations to a network of advanced therapies and quality of care. Among the pathogenetic factors, a significant proportion of the latest research is focused on the gut microbiome, as rapidly changing environmental factors exert their effects primarily by altering the microbiome. This book highlights the enigmatic crosstalk between the gut microbiome and CD. Going further, CD is a great mimicker that is important to differentiate from other diseases, especially intestinal tuberculosis, which is still a significant problem in tuberculosis-endemic countries. This book addresses this issue as well. Among the diagnostic modalities, capsule endoscopy is a non-invasive, radiation-free, and accurate modality for pan-enteric evaluation. The book examines the role of capsule endoscopy in suspected and established CD, including its pros and cons in these scenarios. It also highlights technical advancements in the field.
