Atsushi Imagawa et al. Water consumption during bowel preparation for colonoscopy before and after a simple infographic-based intervention: a prospective observational study Although the environmental impact of endoscopy is still high owing to patient transport, scope cleansing, and use of consumables, a simple intervention with patient education on toilet flushing during bowel preparation significantly reduced the amount of water used for flushing. While the per-session reduction was only modest, implementing these measures on a regional or national scale could result in significant water conservation over time.
