Drinking water before endoscopy is safe and does not impact view quality. However, consuming milk prior to the procedure leads to significantly poorer mucosal views, making it unsuitable.

Area of Science:

  • Gastroenterology
  • Endoscopic Procedures
  • Digestive Physiology

Background:

  • Traditional pre-endoscopy fasting protocols may be unnecessarily restrictive.
  • Previous research indicated that drinking water before endoscopy does not compromise mucosal visualization or gastric fluid volume.
  • The current study investigates the safety and efficacy of consuming milk, a fluid that may affect gastric emptying, prior to endoscopy.

Purpose of the Study:

  • To determine if drinking milk 90 minutes before upper gastrointestinal endoscopy adversely affects gastric fluid volume, pH, or mucosal view quality.
  • To compare the effects of milk versus water consumption on endoscopic outcomes.

Main Methods:

  • Forty-eight patients undergoing routine upper gastrointestinal endoscopy were randomized to consume 200 ml of either still mineral water or full-fat milk after an overnight fast.

  • Endoscopy was performed 90 minutes post-consumption.
  • Residual gastric fluid volume and pH were measured, and the quality of the mucosal view was assessed.

    • Main Results:

    • No significant differences in residual gastric fluid volume or pH were observed between the water and milk groups.
    • Patients who drank milk experienced significantly poorer mucosal views compared to those who drank water (p < 0.001).
    • The trend indicated a clear negative impact of milk consumption on endoscopic visualization quality.

    Conclusions:

    • Drinking water up to 90 minutes before endoscopy is a safe practice.
    • Milk consumption prior to endoscopy should be discouraged due to its detrimental effect on mucosal views.
    • These findings suggest a need to revise pre-endoscopy fluid intake recommendations.
