What is the purpose of a water flush during flexible endoscopy?

• A. To enhance the effectiveness of sedation
• B. To clear mucus and debris from the lens for improved visualization
• C. To test the pressure in the gastrointestinal tract
• D. To prepare the patient for discharge

Answer: (B)

The purpose of a water flush during flexible endoscopy is primarily to clear mucus and debris from the lens, which significantly improves visualization during the procedure. Flexible endoscopes are equipped with high-definition cameras that require a clear view to obtain accurate and informative images of the internal structures being examined. If the lens becomes obscured by mucus or other particles, it can hinder the endoscopist's ability to see the area of interest clearly, potentially affecting the accuracy of the assessment and any interventions that may be needed. Implementing a water flush helps maintain the cleanliness of the lens, ensuring that the endoscopist can visualize the anatomy and any pathological changes without obstruction. This practice enhances the overall safety and effectiveness of the endoscopic procedure, helping to increase the likelihood of identifying conditions or lesions accurately during the examination.
