Capsule Endoscopy-Where Are We at 2011 and Where Are We Headed?

Since its introduction over 10 years ago, capsule endoscopy has become an important investigational tool of small bowel, and thereafter of esophageal and colonic pathologies. Over the years, 2nd generation capsules were developed for all three sites, as was a non-video 2nd generation agile patency capsule to confirm functional patency of the GI tract. Three additional competitive small bowel video capsules have been introduced as well (EndoCapsule, Miro capsule and the OMOM capsule). The present review will describe the available capsules in the market, the procedure itself, present indications and future expectations.
