Microbiological and Organizational Impact of the Use of Bacteriologically Controlled Water in COLOscopy

This study examines whether it is safe — from a microbiological standpoint — to use reusable bottles of bacteriologically controlled water instead of single-use sterile water bottles during colonoscopies that use a water-flushing technique. The water-exchange method (irrigating the colon with water during colonoscopy) improves comfort and polyp detection, but requires about one liter of water per procedure, generating significant waste. Adults of legal age who are scheduled for a routine colonoscopy on specific days and shifts at the study site are eligible. Participation involves undergoing the colonoscopy as planned, with a 200 mL water sample collected from the wash bottle at the end to check for bacterial contamination. This summary was generated with AI assistance and is intended to help patients understand the study in plain language.
