Colonic preparation before colonoscopy in constipated and non-constipated patients: A randomized study

Table 1 Bowel preparation quality grading score used by the endoscopists

Excellent	No fecal matter or nearly none in the colon, small-to-moderate amounts of clear liquids
Good	Small amounts of thin liquid fecal matter seen and easily suctioned, mainly distal to splenic flexure, small lesions may be missed, > 90% mucosa seen
Fair	Moderate amounts of thick liquid to semisolid fecal matter seen and suctioned, included proximal to splenic flexure, small lesions may be missed, 90% mucosa seen
Poor	Large amounts of solid fecal matter found, precluding a satisfactory study, unacceptable preparation; < 90% mucosa seen
