Aims:

The data on the salvage option for patients whose bowel preparation is predicted to be inadequate are limited. This study aimed to evaluate the impact of additional oral preparation at the same day of colonoscopy on the quality of bowel preparation in patients showing opaque yellow with particles or brown effluent.

Methods:

Between September 2015 and June 2018, a multicenter, prospective endoscopist-blinded randomized controlled trial was conducted. Patients reporting their last effluent as opaque yellow with particles or brown at the time of arrival to the endoscopy unit were randomized to additional oral preparation (further preparation with 1L of PEG+Asc) group vs. Control (strongly recommend walking without taking additional purgative) group. All colonoscopies were performed on the afternoon. Bowel preparation was considered to be adequate if total Boston Bowel Preperation Scale (BBPS) ≥5 points in per-protocol analysis.

Results:

A total of 157 patients were enrolled (male, 53.5%, 61.4 ± 13.9 years old). Adequate bowel preparation was significantly higher in patients assigned to additional oral preparation group compared with control (83.3% vs.61.0%, p = 0.002). More patients allocated to additional oral preparation group showed nausea during the preparation compared with those in control. There were no difference in willingness to repeat bowel preparation between two groups.

Conclusions:

Additional oral preparation could be considered in patients who is predicted to be inadequate bowel preparation before colonoscopy. ClinicalTrial.gov (NCT02540031).
