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.

Condition or disease Intervention/treatment Phase
Gastrointestinal Bleeding Procedure: CT enterography Device: video capsule endoscopy Not Applicable

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 Intervention/treatment
Experimental: obscure gastrointestinal bleeding
Those patients who developed obscure gastrointestinal bleeding either overt or occult bleeding who will then undergo video capsule endoscopy and CT enterography.
Procedure: CT enterography
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.

Device: video capsule endoscopy
Video capsule endoscopy is performed using PillCam SB (Given Imaging, Yokneam, Israel). Polyethylene glycol (NIFLEC) is used for bowel preparation.

Primary Outcome Measures :
  1. number of significant gastrointestinal lesions detected [ Time Frame: up to 1 month ]
    Significant gastrointestinal lesions are ulcers, mucosal inflammation, angiodysplasia, and mass.
