There remains debate regarding whether small bowel cleansing is required prior to video capsule endoscopy, and if so, which method is best. This study prospectively tests cleansing with no preparation, preparation with picosalax, and preparation with polyethylene glycol.

Condition Intervention Phase
Drug: Clear fluids
Drug: Picosalax
Drug: Polyethylene glycol
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Diagnostic
