Brief Summary

Colonoscopy is the gold standard diagnostic procedure for colonic disease. Excellent bowel cleansing is critical for this procedure. However, an inadequate bowel cleansing is a common problem that occurs up to 20% of procedures. This fact has a deep clinical and economical impact. In fact, inadequate bowel preparation is associated to misdiagnosis in 30% of lesions. Moreover several clinical conditions such as cirrhosis, antidepressant drugs, and hospitalized patients are predictive factors of inadequate colonic preparations. These circumstances have promoted multiple clinical trials, however there is no consensus about the optimal strategy for colonic cleansing. Education in colonic preparation has obtained conflicting results. Polyethylene glycol (PEG) and sodium phosphate solutions have been the commonest preparations used with a similar efficacy. However, the large volume to ingest (4 litters) makes PEG compliance difficult. Likewise, sodium phosphate also contains high levels in sodium and phosphate which contraindicate its use in elderly patients and / or with comorbidity. The use of adjuvants such as olive oil and bisacodyl allows reducing the volume of polyethylene glycol thereby improving the tolerance and right colon preparation.

The aim of this study is to compare the efficacy of a multidisciplinary approach (education, fiber free diet, polyethylene glycol (PEG) 2L, and adjuvant bisacodyl + olive oil) vs. a conventional approach (fiber free diet+ PEG 4L in split doses ) in cleaning the colon of hospitalized patients.

Primary Outcome Measures
NameTimeMethod
percentage of patients with adequate bowel preparationat the time of performing the colonoscopy

Adequate bowel preparation is defined as a preparation which allows exploring the whole colonic mucose and detecting flat lesions (Rating as good or excellent in the Boston Bowel preparation scale)

Secondary Outcome Measures
NameTimeMethod
Percentage of patients with adequate bowel preparation by bowel segmentsAt the time of performing the colonoscopy

The boston scale will be assessed by the investigators during the procedure.

Tolerance to the colonoscopyfrom colonoscopy up to 24 hours after colonoscopy

Tolerance to the colonoscopy will be measured by VAS during the colonoscopy, 30 minutes after colonoscopy and 24 hours after colonoscopy

Percentage of complete/incomplete colonoscopies and reprogrammingAfter the colonoscopy

Evaluation of incomplete or inadequate bowel preparation will be assessed after performing the colonoscopy

Complications during and after the procedureup to 24 hours after colonoscopy
Doses of sedation needed during the colonoscopyDuring the colonoscopy process

Final dose will be calculated at the end of the procedure

Tolerance to the preparationup to 48 hours
Endoscopic findingsduring the colonoscopy
