Gastroscopy, also known as esophagogastroduodenoscopy, is an endoscopic procedure used to examine the esophagus, stomach, and small intestine (duodenum).

When is gastroscopy performed?                 

Gastroscopy is usually performed to diagnose and treat conditions such as:

• Upper gastrointestinal tract diseases;
• Ulcers;
• Inflammation;
• Bleeding;
• Tumors.

Additionally, tissue sampling (biopsy) may be performed for further cytological or pathomorphological examination.

How to prepare for gastroscopy?                                       

At least 14-16 hours before the procedure, you should stop eating, and 4-5 hours before, you should refrain from drinking water. For better visualization, the stomach must be empty.

Your doctor will also review your medical history. Before the procedure, dose adjustments or cessation of certain medications may be required, in case of taking blood thinners or insulin.

The specialist may also provide additional instructions based on your needs.

How is gastroscopy performed?

During gastroscopy, a thin, flexible tube called an endoscope is inserted into the mouth. The tube with a small camera and a light, is carefully maneuvered into the digestive tract, allowing the endoscopist to see the inner lining of the digestive system on a screen.

Before the procedure, local analgesia (numbing) is applied to reduce discomfort by spraying lidocaine into the throat. Intravenous sedation may also be administered upon the patient’s request for short-acting anesthesia.
