How is small bowel capsule used for endoscopy of the small bowel in patients with GIBOO

How is small bowel capsule used for endoscopy of the small bowel in patients with GIBOO? 

The most widely available and most commonly performed endoscopic test to evaluate the small bowel for GIBOO is small bowel capsule endoscopy. This capsule primarily supplies images of the small bowel, but can also supply limited images of the esophagus, stomach, and cecum. The capsule contains a light source to illuminate the gut, one or more cameras for color photography, a wireless transmitter to transmit the images electronically, and a battery to power these electronic operations. A recorder is usually worn by the patient to receive the transmitted images. The capsule battery generally permits transmission of endoscopic images for approximately 8 hours. The capsule is swallowed with water and passively traverses the alimentary tract by peristalsis. Patients fast overnight before the procedure and should receive a liquid polyethylene glycol–3350 bowel preparation shortly before the procedure to evacuate luminal debris and provide a clear fluid interface. 

Three small bowel capsule brands are commercially available. The PillCam is the latest model produced by Given Imaging (Yoqneam, Israel), which developed the first device. It has a variable frame rate, ranging from two frames per second when stationary up to six frames per second when moving quickly. Other brands include the EndoCapsule by Olympus Corporation (Allentown, PA), and the MiRoCam capsule marketed by Medivators, Inc. (Minneapolis, MN), which was recently approved for use in America.
