Bacteriologically controlled reusable water bottles for colonoscopy.
Evaluation of the Microbiological and Organizational Impact of the Use of Bacteriologically Controlled Water in COLOscopy for an Evolution of Our Practices Towards a More Ecoresponsible Endoscopic Activity COLO SOUS L'EAU
NA · University Hospital, Bordeaux · NCT06688955
We will test whether using bacteriologically controlled reusable water bottles during colonoscopy is microbiologically safe for adults having scheduled colonoscopies at Bordeaux University Hospital.

What this trial studies
Colonoscopy using the water-exchange technique requires about 1 L of water per patient and can improve scope progression, comfort, and polyp detection. This single-center interventional project at CHU de Bordeaux will use bacteriologically controlled water in reusable wash bottles and collect a 200 ml sample from each bottle after the procedure for bacteriological analysis. The study will also set up and assess a sterilization and reconditioning circuit for the bottles, gather staff feedback on feasibility and acceptability, and compare the carbon footprint and waste generation versus single-use sterile bottles. Findings will indicate whether the reusable-bottle process is microbiologically safe and operationally practical for wider adoption.
Who should consider this trial
Good fit: Adults scheduled for a colonoscopy in room 4 during the Monday or Tuesday morning shifts at CHU de Bordeaux who can give informed consent and are covered by social security.
Not a fit: Patients who are pregnant, require emergency colonoscopy, need indigo-carmine chromoendoscopy, are under guardianship, or lack social security coverage are excluded and would not benefit from participation.
Why it matters
Potential benefit: If successful, this could let centers replace single-use sterile bottles with safe reusable bottles, reducing plastic waste and sterilization costs without increasing infection risk.
How similar studies have performed: While water-exchange colonoscopy is supported by international recommendations, the specific use of bacteriologically controlled water in reusable bottles has not been previously validated and remains largely untested.
