Infectious Diseases of the Small Intestine

Infectious diseases of the small intestine are prevalent around the world. Intestinal infections can be caused by viruses, fungi, bacteria, and parasites. Conventional endoscopy has a limited role in the evaluation of infectious disease of the small intestine. Capsule endoscopy is a noninvasive modality to examine the small bowel. The characteristic capsule endoscopic features of select diseases have been described to help diagnose and manage these conditions. However, the role of capsule endoscopy in small intestinal infections is still evolving.
