Feasibility and safety of string, wireless capsule endoscopy in the diagnosis of Barrett's esophagus.

Background: Capsule endoscopy is a major technological advancement in the visualization of the small bowell. Its utility in the evaluation of the esophagus is mainly limited by its rapid and unpredictable transmission, thus limiting the number of pictures of the esophagus, in particular, the distal esophagus.

Methods: Strings were attached to the wireless capsule endoscopy device to allow its controlled movement up and down the esophagus.
