Gastroscopy

What is Gastroscopy?

• Gastroscopy is an endoscopic procedure used to directly view the lining of the esophagus, stomach, and duodenum. A gastroscope, a thin, flexible tube with a camera and light source on its end, is inserted through the mouth, allowing the doctor to examine the upper part of the digestive system in detail.

Why Is Gastroscopy Performed?

​

• Gastroscopy is often used to diagnose and treat the following conditions:

• Long-lasting stomach pain

• Difficulty swallowing

• Heartburn and reflux complaints

• Nausea and vomiting of unknown cause

• Upper gastrointestinal bleeding

• Suspicion of stomach ulcer

• Diagnosis of Helicobacter pylori infection

• Suspicion of a tumor in the stomach or esophagus

How is Gastroscopy Performed?

• Preparation: The patient must fast for 6-8 hours before the procedure. Drinking water is generally allowed up to 2 hours before.

• Application: The patient is laid in a side position. A local anesthetic spray is applied to the throat to reduce the swallowing reflex. If desired, mild sedation (sleep state) can also be provided.

• Procedure Time: Gastroscopy usually takes 5-10 minutes.

• Biopsy: If necessary, small tissue samples can be taken during the procedure. This procedure is painless.

Things to Consider After Gastroscopy

• There may be a slight burning or discomfort in the throat after the procedure.

• If sedation is used, the patient is kept under observation for several hours.

• Oral food should not be taken for the first few hours; after doctor's approval, water and soft foods can be started.

• If a biopsy was taken, results will be available within a few days.

When Should Gastroscopy Be Performed?

Gastroscopy is preferred in the following cases:

1. Difficulty swallowing, painful swallowing, or a feeling of being stuck when swallowing.

2. Abdominal pain, heartburn, excessive gas or burping.

3. Unexplained weight loss.

4. Nausea, vomiting or suspected bleeding.

5. Iron or Vitamin B12 deficiency.

6. Complaints such as bad breath.

In some cases, the procedure is performed under sedation (light anesthesia) so that the patient is completely asleep; this both increases patient comfort and allows the doctor to perform the procedure more comfortably.
