摘要

Aim

Quality of bowel cleansing significantly increases the shorter the time between bowel solution intake and endoscopic examination. We tested the efficacy and patient tolerability following a modified polyethylene glycol electrolyte (PEG) splitting regimen.

Methods

This was a prospective, single-blind, randomized, study. Patients were assigned to receive either PEG 4 L the afternoon before colonoscopy or PEG 3 L the day before and 1 L 3 h before the procedure the day of colonoscopy.

Results

The study population consisted of 336 patients, including 168 participants in each study arm. Although the bowel preparation quality was similarly quoted as excellent/good following the split and full regimen (95.2%vs 92.8%; p = 0.3), a significant (p < 0.0001) shift from good towards an excellent preparation (26.8%vs 68.4%) was observed following the split regimen as compared to the full regimen (55.4%vs 37.5%). The incidence of side-effects did not differ. When patients were asked about a future preparation if needed, 69%and 31%following the split and full regimen, respectively, declared to accept again the same preparation, the difference being statistically significant (p < 0.001).

Conclusions

Our data found that an excellent bowel cleansing could be frequently achieved by simply modifying the split regimen from the standard PEG 2 plus 2 L to 3 plus 1 L.
