• Panchromoendoscopy using Oral Indigo Carmine Mixed with Polyethylene Glycol Prep Scottsdale/Phoenix, Ariz.

  This study first is designed to see what dose of indigo carmine ingested orally mixed with the standard colonoscopy prep is needed to provide adequate staining of the right colon. It then will use this adequate staining concentration of Indigo Carmine to study whether this dye will increase the detection of polyps during colonoscopy.
