Objective: To compare the effectiveness of polyethyleneglycol and mannitol bowel preparation by Boston scale, in patients from the outpatient gastroenterology in the third quarter of 2012. Method: Prospective, cross, experimental with a sample of 100 patients randomized to group polyethyleneglycol and mannitol group, 50 in each. All were introduced liquid diet the day before the test with the appropriate indication for the intake of the solution to evaluate and colonoscopy was performed endoscopic evaluation scale as Boston. Result: tolerance was considered easy preparation by 88% in polyethyleneglycol group vs 100% mannitol group (p=0.041). 98% mannitol group had considered that this medicine palatable compared with polyethyleneglycol (78%) (p=0.002). The most common adverse event in both groups was nausea. Polyethyleneglycol reached full scans with remains at 82% right colon, transverse colon 56% and 72% left colon, whereas mannitol prevailed without full exploration remains at 66%, 90% and 68% respectively (p<0,05). The overall rating scale was polyethyleneglycol Boston 6 vs 8 in the mannitol group (p<0,05). Conclusions: mannitol was more effective for the preparation of polyethyleneglycol entire colon and segments.
