Upper Gastrointestinal Endoscopy (Esophagogastroduodenoscopy, EGD)

Upper gastrointestinal endoscopy (esophagogastroduodenoscopy, EGD) is a modern diagnostic procedure that allows the physician to examine the lining of the esophagus, stomach, and duodenum using a flexible endoscope equipped with a high-definition camera.

What does an upper GI endoscopy show?

During the procedure, the physician evaluates:

The lining of the esophagus, stomach, and duodenum
Inflammation, erosions, ulcers, polyps, and tumors
Signs of bleeding or gastroesophageal reflux disease (GERD)
Tissue samples (biopsy), when necessary, for histopathological examination
The possibility of performing a rapid Helicobacter pylori test to detect the bacteria associated with gastritis and peptic ulcer disease

In addition to diagnosing gastrointestinal disorders, upper GI endoscopy can also be used for therapeutic procedures, including polyp removal, bleeding control, and follow-up evaluation after treatment.

Benefits

Safe and minimally invasive procedure
Highly accurate diagnosis of upper gastrointestinal diseases
Ability to perform a biopsy or therapeutic intervention during the same procedure
Typically completed within 5–15 minutes

Location: Almaty, Aksai-5 district, 12A

Preparation

Do not eat for 8–12 hours before the examination. Your last meal should be no later than 8:00 PM the evening before the procedure.
Do not drink water or other fluids for at least 4 hours before the examination, as this may affect visualization.
Do not smoke on the day of the procedure, as smoking increases gastric secretions and may trigger the gag reflex.
Inform your physician about any medications you are taking, particularly blood thinners (anticoagulants) or aspirin, as these may affect the ability to perform a biopsy.
Inform your physician if you have allergies to local anesthetics (such as lidocaine) or if you wear removable dentures.
Bring your physician's referral (if applicable) and the results of any previous upper GI endoscopy examinations.

After the Procedure

If local anesthetic spray is used, do not eat or drink for 30 minutes, or until normal sensation in your throat has returned.

A written medical report with the examination findings is usually provided immediately after the procedure.

Upper GI endoscopy may be recommended for patients with:

Heartburn or upper abdominal pain
Nausea, vomiting, or a persistent unpleasant taste in the mouth
Suspected gastritis, peptic ulcer disease, gastroesophageal reflux disease (GERD), or tumors
Unexplained anemia or suspected gastrointestinal bleeding
Follow-up after treatment of esophageal or gastric disorders
Detection of Helicobacter pylori infection
