Upper Endoscopy (EGD) Services in New Jersey

Persistent heartburn, trouble swallowing, upper abdominal pain, nausea, or unexplained digestive symptoms may require a closer look at the upper digestive tract.

AZZ Medical Associates provides upper endoscopy (EGD) services in New Jersey to evaluate the esophagus, stomach, and first part of the small intestine. Our gastroenterology team reviews your symptoms, medical history, medications, and previous test results to determine whether an upper endoscopy is appropriate.

What Is an Upper Endoscopy?

An upper endoscopy is a procedure that allows a gastroenterologist to examine the lining of the upper gastrointestinal tract using a thin, flexible tube with a small camera.

It is also known as upper GI endoscopy, EGD, or esophagogastroduodenoscopy. The procedure examines the esophagus, stomach, and duodenum, which is the first part of the small intestine.

An EGD can also allow your gastroenterologist to take a biopsy or perform certain treatments during the same procedure when needed.

When Is an Upper Endoscopy Recommended?

Not every episode of heartburn or stomach discomfort requires an endoscopy. Your gastroenterologist may recommend an EGD when symptoms are persistent, unexplained, worsening, or require further evaluation. Common reasons include:

Persistent acid reflux or heartburn
Difficulty or pain when swallowing
Persistent upper abdominal pain
Frequent nausea or vomiting
Unexplained upper digestive symptoms
Suspected stomach or duodenal ulcers
Barrett’s esophagus evaluation
Abnormal findings from another digestive test
Possible celiac disease
Gastrointestinal bleeding

What Can an Upper Endoscopy Detect?

An upper endoscopy gives your gastroenterologist a direct view of the upper digestive tract and may help identify:
If an abnormal area is seen, a small tissue sample may be taken for laboratory testing.

Biopsy During an Upper Endoscopy

A biopsy may be taken during an EGD to evaluate inflammation, abnormal tissue, Barrett’s esophagus, celiac disease, certain infections such as H. pylori, or other gastrointestinal conditions.

Taking a biopsy does not automatically mean cancer is suspected. Biopsies are commonly used to help confirm a diagnosis.

If tissue is collected, it is sent to a pathology laboratory. Your gastroenterologist will review the results and explain whether treatment or additional follow-up is needed.

Preparing for Your Upper Endoscopy

Your stomach needs to be empty so your gastroenterologist can clearly and safely examine the upper digestive tract.

You will receive specific instructions about when to stop eating and drinking before the procedure. Your provider may also review prescription medications, blood thinners, diabetes medications, supplements, allergies, and previous reactions to sedation.

Do not stop prescription medication unless your healthcare provider specifically instructs you to do so.

What Happens During an Upper Endoscopy?

Sedation is commonly used to help keep you comfortable during an EGD.

A gastroenterologist carefully guides the flexible endoscope through the mouth, down the esophagus, and into the stomach and duodenum. A small camera allows the lining of the upper digestive tract to be examined closely.

During the procedure, your gastroenterologist may take a biopsy, evaluate abnormal areas, treat certain sources of bleeding, or perform other necessary endoscopic treatments.

What Happens After an Upper Endoscopy?

After the procedure, you will remain in recovery while the effects of sedation wear off.

Some patients experience temporary bloating, mild nausea, or a sore throat. If sedation was used, you will generally need someone to drive you home.

Your gastroenterologist may discuss the initial findings soon after the procedure. If tissue samples were taken, pathology results may require additional time.

Your follow-up plan will depend on the findings and the reason the procedure was performed.
