Recommendations
Salvage Options for Inadequate Preparation
➤ Large-volume enemas can be attempted for patients who, presenting on
the day of colonoscopy, report brown effluent despite compliance with
the prescribed colon-cleansing regimen. (Weak; Very Low Quality of
Evidence)
➤ Through-the-scope enema with completion colonoscopy on the same day
can be considered, especially for those patients who receive propofol
sedation. (Weak; Very Low Quality of Evidence)
➤ Waking the patient entirely from sedation and continuing with further
oral ingestion of cathartic with same-day or next-day colonoscopy has
been associated with better outcomes than delayed colonoscopy.

Evaluation
Table 1. Aronchick Bowel Preparation Scale
Excellent Small volume of clear liquid or >95% of surface seen
Good Large volume of clear liquid covering 5%–25% of the surface but
>90% of the surface seen
Fair Some semisolid stool that could be suctioned or washed away
but >90% of the surface seen
Poor Semisolid stool that could not be suctioned or washed away and
<90% of the surface seen
Inadequate Re-preparation needed
