Fibrogastroscopy (FGS) - this is an examination of the esophagus, stomach and duodenum (the first bend of the small intestine). A thin flexible tube (fibrogastroscopy) is passed through the mouth, going through the esophagus and reaching the stomach and the duodenum, looking for diseases of these organs such as:  gastroesophageal reflux disease, peptic ulceration and duodenal ulcers, benign and malignant tumours. Fibrogastroscopy allows specialists to take samples for the histopathology (for diagnostic verification), as well as to perform various therapeutic procedures (for proper treatment).

Indications for carrying out Fibrogastroscopy (FGS)
Fibrogastroscopy is appointed after an examination by a specialist and is carried out mostly with the following indications: difficulty in swallowing, swelling and pain in the upper abdomen, nausea, vomiting, etc.

Preparation and performance
The examination is taken on an empty stomach, so the patient should not eat for at least 10 hours before the procedure. It is a short examination that lasts about 5-15 minutes.
At the beginning, the patient's mouth and throat are anaesthetized with local anaesthesia. A protector is placed in the mouth in order not to injure the instrument, and it gradually passes through it into the esophagus, the stomach and the beginning of the duodenum. The procedure is absolutely painless. Possible slight feeling of nausea.
