Cleansing efficacy and safety of bowel preparation protocol using sodium picosulfate/magnesium citrate considering subjective experiences: An observational study

Table 1 The Ottawa Bowel Preparation Scale (by colon segment)

Score	Description
0	Excellent: Clearly visible mucosal detail with almost no stool residue; any fluid present is clear with hardly any stool residue
1	Good: Some turbid fluid or stool residue, but mucosal detail still visible without the need for washing/suctioning
2	Fair: Some turbid fluid of stool residue obscuring mucosal detail; however, mucosal detail becomes visible with suctioning; washing not needed
3	Poor: Stool present obscuring mucosal detail and contour; a reasonable view is obtained by suctioning and washing
4	Inadequate: Solid stool obscuring mucosal detail, which cannot be cleared by washing and suctioning
