Description Introduction: The outcome of bowel preparation depends on several factors. One such factor is proper timing, especially the duration from completion of the preparation to colonoscopy.This interval should not exceed 4 hours when using polyethylene glycol (PEG). lt is unknown whether this recommenciation is also valici for low-volume formulas. This study aimed to determine the Appropriate timing of bowel cleansing using such formulas. Methods: Subjects referred for a colonoscopy were prepared using PEG/ascorbic acid (MOV), picosulphate/ magnesium citrate (PICO), or sulphate solution (EZI). The quality, tolerability, length of the preparation (T-pripr), and interval from completion of the preparation to colonoscopy (T-vys) were assessed. Results: Preparation quality depended on both T-pripr and T-vys (p s 0.006). The predirted T-pripr in the two best preparations was longer for PICO than for EZI and MOV (> 9.0 vs. > 7.0 and > 6.5 hours, p = 0.01). T-vys was also longest for PICO (5 13.0 hours, p = 0.001). There was no difference between MOV and EZI (< 10 and < 11 hours). Time factors did not affect preparation tolerability. Conclusion: The quality of bowel cleansing depends not only on the interval to colonoscopy but also on the length of the preparation. Optimal time points are cornparable for osmoticagy acting low-volume laxatives, but longer for PICO. Time factors do not affect preparation tolerability.
