BACKGROUND Conventional placement of a wireless esophageal pH monitoring device in the esophagus requires initial endoscopy to determine the distance to the gastroesophageal junction. Blind placement of the capsule by the Bravo delivery system is followed by repeat endoscopy to confirm placement. Alternatively, the capsule can be placed under direct vision during endoscopy. Currently there are ...

1 One of the significant challenges in Capsule Endoscopy (CE) is to precisely determine the pathologies 2 location. The localization process is primarily estimated using the received signal strength from sensors in 3 the capsule system through its movement in the gastrointestinal (GI) tract. Consequently, the wireless 4 capsule endoscope (WCE) system requires improvement to handle the lack of t...

It is a fact that performing endoscopy using conventional methods requires substantial time and development of alternative diagnostic modalities. Replacement of rigid endoscopes with flexible and digital devices in time, faster performance of the procedures and reduced time for them to turn back to work brought about the expectancy. It was possible that easier and more reliable methods could ex...

CT enterography is a new imaging modality that has distinct advantages over conventional CT, wireless capsule endoscopy, and barium examination. CT enterography is noninvasive and allows rapid mapping of disease activity before endoscopy and in cases where the endoscope cannot reach the diseased segment. CT enterography is readily available, is operator independent, and allows evaluation of ext...
