Preface

Since the time when endoscopy and colonoscopy were first introduced, small bowel disorders have remained a diagnostic challenge. The small bowel or the midgut is difficult to assess due to its location and distance from the oral and anal openings. Whereas endoscopy and colonoscopy were commonly used for the diagnosis and treatment of acid peptic, neoplastic, and inflammatory gastrointestinal disorders, the midgut remained an endoscopic mystery. With the exception of surgically assisted scope insertion through a jejunal enterotomy, entry to the small bowel was limited to the edges reaching only to the proximal jejunum or terminal ileum. Imaging modalities like barium studies and computed tomography scans were the

The past few decades have seen many developments in imaging modalities for the small bowel, leading to better diagnosis and focused therapy. This includes the innovation of capsule endoscopy, which was a revolution in small bowel imaging and led to a change in the diagnostic algorithm for obscure gastrointestinal (GI) bleeding. Later advances like double balloon and spiral enteroscopy now provide a therapeutic option for small bowel diseases. Although this book mainly covers the endoscopic aspect of small bowel diseases, we have included a separate chapter on radiological imaging in inflammatory bowel diseases (IBD). Radiological imaging is

an important complementary tool for the diagnosis of small bowel diseases.

This book reviews not only the history and art of small bowel endoscopy but also covers other aspects like endoscopic ultrasound assessment of the duodenal wall, intra-operative endoscopy, and management of small bowel perforations. We hope it will help readers in the management of patients with small bowel diseases.
