NCT04502485

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.

Outcome Measures

Primary Outcomes (1)

  • Discomfort during the procedure

    A VAS discomfort score (0, no discomfort; 10, most discomfort) graded by the patient,

    5 minutes after the procedure

Secondary Outcomes (3)

  • patient satisfaction score

    5 minutes after the procedure

  • mucosa cleanliness score

    1 minutes after the procedure

  • technique adequacy score

    1 minutes after the procedure

Study Arms (2)

Gastric water exchange

EXPERIMENTAL

Air will be minimally insufflated to partially open the lumen and any residual fluid will be suctioned when the scope passes through the esophagus. 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. Air will be opened when the scope enter the prepylorus area where there is usually an air pocket. The scope will enter the duodenal bulb and 2nd portion of duodenum where withdrawal inspection will start.

Procedure: Gastric water exchange

Traditional air insufflation

ACTIVE COMPARATOR

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.
