When digestive symptoms persist or cannot be fully explained through an office evaluation alone, a gastroenterologist may recommend an upper endoscopy. For patients in The Woodlands, TX, this procedure can provide a closer look at the upper digestive tract and help physicians investigate symptoms involving the esophagus, stomach, and beginning of the small intestine.
An upper endoscopy is also called an EGD, or esophagogastroduodenoscopy. It uses a thin, flexible instrument equipped with a camera so the gastroenterologist can visually examine areas of the upper gastrointestinal tract.
What Can an Upper Endoscopy Help Diagnose?
A gastroenterologist may recommend an EGD or upper endoscopy when a patient has persistent symptoms that require further investigation.
Depending on the individual, these may include:
- Persistent heartburn or acid reflux
- Difficulty swallowing
- Upper abdominal pain
- Ongoing nausea or vomiting
- Gastrointestinal bleeding
- Unexplained anemia
- Other persistent upper digestive symptoms
An upper endoscopy may allow the physician to identify inflammation, ulcers, growths, or other abnormalities. Tissue samples, called biopsies, may also be collected when medically appropriate.
What Happens During an Upper Endoscopy?
During an upper endoscopy, a gastroenterologist guides a flexible endoscope through the mouth and into the upper digestive tract. A small camera allows the physician to examine the esophagus, stomach, and duodenum.
The procedure is generally performed in an outpatient setting. Patients receive specific preparation instructions beforehand and need to arrange for an adult to drive them to and from the procedure. The practice advises patients not to drive or make important decisions on the day of the procedure.
Patients can explore the practice’s other gastrointestinal diagnostic procedures to learn about additional testing that may be recommended based on their symptoms.
Is an Upper Endoscopy the Same as a Colonoscopy?
No. Although both are endoscopic procedures performed by gastroenterologists, they examine different parts of the digestive system.
An upper endoscopy examines the upper gastrointestinal tract, including the esophagus, stomach, and beginning of the small intestine. A colonoscopy examines the large intestine and rectum.
Which procedure is appropriate depends on a patient’s symptoms, medical history, risk factors, and the clinical judgment of the treating physician.
Can a Gastroenterologist Take a Biopsy During an EGD?
Yes. If a physician identifies an area that needs additional evaluation, small tissue samples may be collected during the procedure and sent for laboratory analysis.
Biopsies may be used to help investigate conditions associated with inflammation, bleeding, H. pylori, anemia, or other abnormalities. A biopsy does not automatically mean that cancer is suspected; tissue sampling can be useful for diagnosing several gastrointestinal conditions.
When Should You Ask a Gastroenterologist About an Upper Endoscopy?
Persistent symptoms deserve appropriate medical evaluation. If heartburn, swallowing problems, upper abdominal discomfort, nausea, or other digestive concerns continue or worsen, a physician can determine whether an upper endoscopy or another diagnostic approach is appropriate.
