Registration Number
NCT01909219
Lead Sponsor
Luigi Sacco University Hospital
Brief Summary

This is an endoscopist-blinded, prospective, multicenter study involving adult outpatients aiming at evaluating whether sodium picosulphate/magnesium citrate split dosing is associated to higher efficacy and acceptability in comparison to the standard dose regimen in bowel cleansing before colonoscopy

Detailed Description

Picosulphate/magnesium citrate is a very effective, safe and tolerated low-volume preparation for colon cleansing. This study evaluates whether split dosing is associated to a further increase in efficacy and acceptability in comparison to the standard dose regimen. This is a multicenter, randomized, single-blind study performed in 15 endoscopic services in Italy.

Adult outpatients undergoing colonoscopy will receive picosulphate/magnesium citrate either in the standard dosing (group A, two sachets the day before endoscopy), or in the split dosing (group B, the second dose in the morning of colonoscopy). Bowel cleansing will be assessed using the Boston Scale (BBPS) and rated as adequate if \>2 in each segment. Patient acceptance, satisfaction, and related symptoms will be also recorded.

GroupInterventionDescription
Group BSodium picosulphate/magnesium CitratePatients in the group B (split regimen) will be instructed to take the first sachet of sodium picosulphate/magnesium citrate at 7 pm the day before colonoscopy and the second one at 6 am in the morning on the day of colonoscopy.
Group A: standard regimenSodium picosulphate/magnesium CitratePatients in the group A (standard regimen) will be instructed to take the two sachets of sodium picosulphate/magnesium citrate diluted in a glass of water 2-4 hours apart, starting at 5 pm the day before colonoscopy.
Primary Outcome Measures
NameTimeMethod
Rate of adequate colon cleansing24 hrs

The primary endpoint of the study was the quality of overall colon cleansing, assessed by the endoscopist. Colon cleansing quality was dichotomized as "adequate" (score \> 2 in each colon segment) or "inadequate" (score \< 2 in one or more colon segments

Secondary Outcome Measures
NameTimeMethod
Patients' acceptance, tolerability and compliance to the cleansing regimen24 hrs

The overall tolerance of the preparation and the severity of symptoms during the preparation period will be rated on a scale ranging from 0 (no discomfort) to 3 (severe discomfort). Patient acceptance of the preparation will be evaluated by a questionnaire with a 5-point scale ranging from 1 (worse) to 5 (best), assessing interference with daily activity, palatability, easiness in taking the product and the adjunctive clear fluid, and taste of product. Moreover, a nurse will ask the patient whether s/he have completed the prescribed regimen: compliance will be defined as poor for patients who consume less than 75% of product. Willingness to repeat the same preparation in the future will be also recorded.
