Wireless Capsule Endoscopy of the Small Intestine
Wireless Capsule Endoscopy of the Small Intestine
Multiple capsule systems are available worldwide of which two Food and Drug Administration and capsule endoscopy-certified capsule devices are currently available (Table 1). Both are plastic capsules of disposable use. The Given (Given Imaging Ltd., Yokneam, Israel) small bowel capsule measures 11 × 26 mm and has a weight of less than 4 g. The field of view is 140° and the system can detect objects less than 0.1 mm. The SB2/4 capsule is capable of capturing four images per second. The operating time is between 6–8 h. The Given capsule for esophageal diseases (PillCam Eso) has the same size as the small bowel capsule but is capable to take up to 18 images per second as it passes down the esophagus. The endocapsule system from Olympus (Olympus, Tokyo, Japan) has a maximum field of view of 145°, a depth of field between 0–20 mm and a sampling rate of two frames per second. The dimensions of the capsule are 11 mm in diameter and 26 mm in length. The operating time of the device is about 8 h.
