PillCam ESO video capsule is designed specifically to help the doctor see inside the esophagus to diagnose diseases such as esophageal varices. PillCam ESO contains an imaging device and light source at both ends of the capsule and takes up to 14 images per second or a total of 2,600 color images as it passes down the esophagus PillCam ESO provides patient-friendly alternative to esophageal endoscopy and the associated sedation and discomfort.

Increasing intra-abdominal pressure (IAP) with an abdominal binder will increase pressure within smaller esophageal varices which will therefore enhance the ability of capsule endoscopy to detect these varices better. Therefore, the aims of the current study are to determine if using an abdominal binder to increase IAP can increase the detection rate of small esophageal varices when using capsule endoscopy and to determine if using an abdominal binder to increase IAP during capsule endoscopy has a comparable detection rate of small esophageal varices to conventional endoscopy.
