Abstract
Colonoscopy is commonly accepted as the procedure of choice for the detection and treatment of colonic lesions. The current study was undertaken to compare effectiveness and tolerance of different bowel preparations. Three hundred patients were randomized into three groups, to be administered either a senna compound, a polyethylen glycol lavage, or an oral sodium phosphate (NaP) solution. Tolerance of the preparation was considered. After each colonoscopy, the endoscopist blindly scored cleansing for each bowel segment and defined the quality of the examination as “optimal,” “acceptable,” or to be repeated. Significantly more patients in Group C (68%) achieved a “good” cleansing compared with Group B (50%;P P
