Endoscopic Procedures I: Esophagogastroduodenoscopy

Esophagogastroduodenoscopy is a diagnostic endoscopic procedure that visualizes the oropharynx, esophagus, stomach, and proximal duodenum.

It helps diagnose conditions such as GERD, peptic ulcers, gastritis, Barrett's esophagus, and celiac disease.

During the procedure, the patient wears a mouth guard and lies on their left lateral decubitus.

The nurse inserts an intravenous catheter to administer sedation.

Once sedated, a camera-equipped flexible tube is inserted through the mouth to examine.

Insufflation with air or carbon dioxide enhances visibility for real-time visualization of the gastrointestinal lining and allows for interventions such as polyp removal, stricture dilation, and biopsy collection.

After the examination, the endoscope is carefully withdrawn.

Nursing responsibilities include instructing patients to fast for 6 to 8 hours before the test, explaining the test, and obtaining consent.

During the procedure, nurses monitor vital signs and oxygen saturation.

Post-procedure, they observe patients until the sedation wears off and check for complications like bleeding.
