Gastrointestinal Endoscopy
Upper gastrointestinal endoscopy is a diagnostic procedure utilized to examine the inner lining of the esophagus, stomach, and the initial portion of the small intestine using a thin, flexible instrument called an endoscope. During the procedure, the endoscope is inserted through the mouth and gently guided down the throat into the esophagus, stomach, and upper gastrointestinal tract, known as the duodenum.
Commonly referred to as esophagogastroduodenoscopy (EGD), this examination allows physicians to visually inspect for conditions such as ulcers, inflammation, tumors, infections, and sources of bleeding. Additionally, tissue samples can be obtained for biopsy purposes, and polyps may be removed if detected. Furthermore, if bleeding is identified, it can often be addressed immediately using specialized instruments via the endoscope. Importantly, an endoscopy can reveal issues that may not be evident on X-rays and can potentially obviate the need for exploratory surgery in certain cases.
What are the potential risks associated with undergoing this test
While complications associated with this test are uncommon, there is a slight risk of puncturing the esophagus, stomach, or upper small intestine. In the event of a puncture, surgical intervention may be necessary for treatment. Additionally, there is a possibility of infection following the procedure.
When a tissue sample is collected, there is an increased risk of bleeding. However, this bleeding typically stops spontaneously without the need for treatment. In cases where vomiting occurs during the test and particles are aspirated into the lungs, there is a risk of developing aspiration pneumonia.
Furthermore, an irregular heartbeat may occur during the procedure, though it typically resolves on its own without requiring treatment.
