Brief summary

The aim of the study was to evaluate the application of water exchange method to upper endoscopy. We hypothesize that water exchange during upper endoscopy could reduce patient discomfort. The primary outcome will be the patient discomfort score during upper endoscopy. The secondary outcomes will include cleanliness score, techniques adequacy score, findings of the EGD, and willing to repeat the procedure, as well as the patient and endoscopist satisfaction score with the method.

Interventions

PROCEDUREGastric water exchange

Upon entering the fundus of the stomach the air button will be turned off. Air pocket and gastric fluids will be removed by suctioning. Distilled water, delivered by a 50-ml syringe in 10ml-to-20 ml increments, will be infused to dislodge debris and air bubbles adhering the gastric mucosa and open the lumen. The infused water will be removed to keep the lumen almost completely collapsed before the scope advance further.

PROCEDUREtraditional air insufflation

Air will be minimally insufflated and residual fluid suctioned during the entire insertion process. Usually, no water will be infused to cleanse the mucosa until the withdrawal phase.
