What is the main target: a clearer colon with a sennoside-based regime, or adequate bowel cleansing before colonoscopy with a PEG-EL-based regime?

Results: The mean age of the patients and the male distribution were similar in the 2 groups. Both inadequate bowel cleansing and the best cleansed bowels were seen in Group 1. The number of inadequate colonoscopies declined when using a whole bowel-cleansing regime from 24.5% to 19.3% in Group 2, but it did not decline in Group 1. Conclusion: The best bowel cleansing can be achieved with sennoside-based regimes, whereas a greater proportion of adequate results via colonoscopy were reached with the PEG-EL-based regimes.
