The small intestine had represented a "diagnostic gap" that has now been bridged by video capsule endoscopy, which supplements and enhances the results obtained with traditional radiological and endoscopic investigations. It features: the only noninvasive procedure for direct visualization of the entire small intestine - interalia, to assess the source of hemorrhage, inflammations, and tumors; painless, easily managed, feasible on an outpatient basis, without radiation exposure; principles for classification, interpretation, and evaluation of clinical relevance; common and uncommon alterations of the small intestine; normal findings; variants; and postoperative alterations. With the most important corresponding images and findings, it also covers: images of push enteroscopy, sonographic images, X-rays, CT scans; histologies and surgical specimens; additional findings from the entire gastrointestinal tract; practical guide and reference resource; methods, procedure, technique; avoiding and managing complications; structured terminology: reproducible for obtaining findings and diagnoses. This is the definitive work on video capsule endoscopy - a unique achievement.
