Two multicenter trials have evaluated the potential of capsule endoscopy as a diagnostic tool for screening and surveillance of esophageal varices in cirrhotic patients. Their results are similar and show that capsule endoscopy has good performance characteristics, although it is somewhat inferior to esophagogastroduodenoscopy.
