Brief Summary
The purpose of this study is to compare the efficacy between video capsule endoscopy and CT enterography in diagnosis of obscure gastrointestinal bleeding.
Detailed Description
All adult patients with obscure gastrointestinal bleeding will undergo both video capsule endoscopy and CT enterography. The interval between two tests will be less than 1 month. The capsule reading gastroenterologist and the CT reading radiologist are blinded to each others' results.

Arm Title
obscure gastrointestinal bleeding
Arm Type
Experimental
Arm Description
Those patients who developed obscure gastrointestinal bleeding either overt or occult bleeding who will then undergo video capsule endoscopy and CT enterography.
Intervention Type
Procedure
Intervention Name(s)
CT enterography
Intervention Description
CT enterography is performed using 64-channel multi-detector row CT scanners (Siemens Sensation 64, Siemens Medical solution, Forchiem, Germany). Prior to the scan, 1500 cc of a neutral oral-enteric contrast material, polyethylene glycol (NIFLEC) is taken by the patient. During the scan, 2cc/kg of intravenous contrast (iohexol, Ominipaque Amersham GE-Health care, Princeton, NJ) is injected at the velocity 5 cc/sec.
Intervention Type
Device
Intervention Name(s)
video capsule endoscopy
Intervention Description
Video capsule endoscopy is performed using PillCam SB (Given Imaging, Yokneam, Israel). Polyethylene glycol (NIFLEC) is used for bowel preparation.
