Clinical Trial Summary

Bowel preparation is a crucial step prior to colonoscopy to help with the optimal assessment of the colonic mucosa. Inadequate bowel preparation increases the length of the procedure, and is associated with decreased lesional detection rates. The ideal bowel preparation formulation should be able to completely clean the bowel, without leaving solid or liquid residues, and without modifying the mucosal appearance.

Bowel preparation may be administered in hospitalised patients or in the ER. Patients have less control on their environment and the intake of the bowel preparation. For example, there may be a delay in pharmacy delivery or inadequate supervision by the treating personnel. Hospitalised patients have more comorbidities, are usually less autonomous and mobile - both can add to the barriers leading to an adequate bowel preparation. Multiple studies have identified hospitalization status as an independent risk factor for poor bowel preparation.

The objective of this study is to access which bowel preparation regimen, between PEG 3350 with electrolytes 2L the day before and 2L the day of the colonoscopy vs bisacodyl + PEG 3350 with electrolytes 1L the day before and 1L the day of the colonoscopy, results in the cleanest bowel preparation in hospitalised patients.

Intervention

Drug:
• PEG/electrolytes 2L/2L split dose
Polyethylene glycol 17gm X 4 At 18h00 the day prior the colonoscopy, dilute 2 sachets in 2 L of water and drink 240 mL every 10 minutes On the day of the procedure, 4-5 hours prior the colonoscopy, dilute 2 sachets in 2 L of water and drink 240 mL every 10 minutes
• Bisacodyl 15 mg and PEG/electrolytes 1L/1L split dose
Bisacodyl 15 mg x 3 At 14h00 the day prior the endoscopic procedure: take 3 tablets of Bisacodyl ER (15 mg) orally then 5 hr later: PEG/electrolytes 1L/1L Polyethylene glycol 17gm Dilute one sachet of Polyethylene glycol 17gm in 1 L of water Start drinking at around 19h00 the night prior the colonoscopy Drink 240 ml every 10 minutes The day of the colonoscopy. At (4 hrs prior the procedure). Dilute on sachet of PEG and drink 240 ml every 10 minutes

Primary	Efficacy	Which bowel preparation regimen, between PEG 3350 with electrolytes 2L the day before and 2L the day of the colonoscopy vs bisacodyl + PEG 3350 with electrolytes 1L the day before and 1L the day of the colonoscopy, results in the cleanest bowel preparation in hospitalised patients.	following colonoscopy
Secondary	Tolerability	A questionnaire will be used to assess which is the most tolerable and acceptable to patients between the two bowel preparation regimens	Before colonoscopy
