NCT05871801

Brief Summary

The main purpose of the study is to evaluate in a prospective cohort of patients with an appointment for the performance of an outpatient colonoscopy the prediction of the quality of colonic cleansing through the use of 3 predictive models. The colon cleansing quality will be assessed by a validated scale (Boston Bowel Preparation Scale, BBPS). Patients will be prepared with polyethylene glycol (PEG), PEG plus ascorbic acid (PEG-Asc) or sodium picosulfate-oxide magnesium solution (PS).

Conditions

Outcome Measures

Primary Outcomes (1)

  • Rate of poor bowel cleansing assessed by the Boston Bowel Preparation Scale

    Quality of bowel cleansing assessed by the Boston Bowel Preparation Scale. This scale goes from 0 (no preparation) to 3 points (excellent preparation) in the three segments of the colon (proximal, transverse and distal). The maximum score is 9 points

    3 months

Secondary Outcomes (1)

  • Number of predictive factors of poor bowel cleansing

    3 months

Interventions

one day liquid diet will be administered to every patient included in the study and: split-dose bowel preparation with 4 Liters of Polyethylenglycol (PEG) solution, 2 Liters of PEG-Asccorbic acid or 2L sodium picosulphate.

Colonoscopy will be performed to every patient included in the study

Study Population

The researchers will offer to participate in the study to outpatients scheduled for a colonoscopy who meet all the inclusion criteria and none of the exclusion criteria. The researchers will explain the purpose of the study and will ask to sign the informed consent. They will give verbal and written information.

You may qualify if:

  • Age \>18
  • To sign the informed consent,
  • Patients with indication of outpatient colonoscopy
  • Patients ingesting preparation

You may not qualify if:

  • Resection of more than one colon segment.
  • Ileus, intestinal obstruction, megacolon.
  • Poorly controlled hypertension (HTAS\> 180 HTAD\> 100).
  • Terminal renal failure (pre-dialysis or dialysis).
  • Congestive heart failure (NYHA III-IV).
  • Acute liver failure.
  • Severe psychiatric illness.
  • Dementia with difficulty in the intake of the preparation.
  • Pregnancy or breastfeeding.
  • Refusal to participate in the study.
  • Allergies.
  • Incomplete colonoscopy except for poor bowel cleansing
