NCT01887158

Brief Summary

Studies that have investigated different bowel preparations in patients with history of colorectal surgery are surprisingly lacking.Therefore, which is the best colon preparation in this subgroup of patients is still unknown. Polyethylene glycol (PEG)-based solutions are the most popular and safest bowel preparation regimens, however the 4-Liter volume is often poorly tolerated. More recently, it has been shown that the use of a low volume preparation (2-Liter PEG solution with the adjunct of a laxative, bisacodyl) achieves comparable bowel cleanliness rates to 4-Liter PEG in general population.The primary aim will be to compare the efficacy of 2-L mixed preparation (bisacodyl plus PEG) to 4-L PEG preparation.

Outcome Measures

Primary Outcomes (1)

  • quality of bowel preparation rated according to a modified Ottawa bowel preparation scale

    about 2 weeks after the randomization

Secondary Outcomes (3)

  • Tolerability to the preparation (specific questionaire)

    participants will be followed from the randomization until the time of colonoscopy, about 2 weeks after the randomization

  • safety (adverse event rate)

    participants will be followed from the randomization until the time of colonoscopy, about 2 weeks after the randomization

  • Lesion detection (type and lesion detection rate/patient)

    about 2 weeks from the randomization

Study Arms (2)

bisacodyl plus 2-Liter Polyethylene glycol

ACTIVE COMPARATOR

Patients randomized to the low-volume arm, will be invited to consume 2 sachets of Lovol-esse (Polyethylene glycol) in one liter of water at 8:00 PM the evening before the colonoscopy and 2 sachets in one liter of water 4 hours before their scheduled colonoscopy appointment; furthermore, the patients will be instructed to take three 5-mg tablets of bisacodyl the day before the procedure, at 5:00 PM.

Drug: Polyethylene glycolDrug: Bisacodyl

4-Liter Polyethylene glycol

ACTIVE COMPARATOR

Patients assigned to the high-volume arm will be invited to consume 2 envelopes of Selg-esse 1000 (polyethylene glycol) in 2 litres of water and drink the resulting solution in about 2-3 hours starting at 6:00 PM the evening before the colonoscopy; the day of the procedure, starting 5 hours before the procedure, the patients will be invited to complete the preparation with 2 others envelopes of Selg-esse 1000 (polyethylene glycol) dissolved in 2 litres of water.

Drug: Polyethylene glycol
