title: Capsule endoscopy: a review.
abstract: Capsule endoscopy (CE) is a novel technology that allows direct noninvasive visualization of the entire small intestine. CE permits a detailed examination in the ambulatory setting, allowing identification of clinically relevant lesions, and it is appealing to both patients and providers. There are two types of capsules that are currently commercially available: one specifically designed to view the small bowel and the other for the esophagus. Common indications for small bowel CE include obscure gastrointestinal bleeding, initial diagnosis of suspected Crohn's disease, and other small bowel pathology. The esophageal capsule is currently used to evaluate Barrett esophagus and esophageal varices. It is a well-tolerated procedure with relatively few complications. Although CE performance may be superior to existing technologies, its impact on clinical decision-making and patient outcomes are of even greater importance. Herein lies a review of the latest information on CE, its indications, complications, future utilities, and developing technology.
