Efficacy of Small Bowel Preparation in Capsule Endoscopy

Now days, the endoscopic video-capsule is the more appropriate exam for unexplained gastrointestinal bleeding exploration. The responsible damage of this unexplained bleeding are frequently small vascular damages, hard to be detected in the bowel or ulcerations or tumors. The exam quality can be limited by food residues, bubbles or bile.

30% of damage are probably undetectable because of a lack of visibility. An efficient preparation will probably increased the quality of the video-capsule exploration.

The bowel exploration by endoscopy video-capsule will be realized in the usual condition. The study included 4 steps:

• Inclusion
• Randomization
• Video-capsule exploration
• Reading of the video-capsule exam by endoscopist doctors who are in blind.

Inclusion criteria

• Age >= 18 years old.
• Patients who have an indication for video-capsule endoscopy exploration for unexplained gastrointestinal bleeding associated with anaemia (man : haemoglobin <13 g/dl and woman haemoglobin <12g/dl)
• Less than one year Endoscopic assessment by colonoscopy and gastroscopy
• Not participated to an another clinic study.
• Written consent.

Exclusion criteria

• Age<18 years old.
• General physical health deterioration such as dehydration or cardiac insufficiency.
• Clinical or radiological suspicion of digestive stenosis.
• Oral iron taking in the 4 days before video-capsule exploration.
• Functional or organic disorders of the gulp
• Pregnant women.
• Sensibility known about the polyethylene glycol.
• No signed consent.
