Video endoscopes typically contain a video camera, light source, air channel, water channel, by all of them can perform interventional operations such as injecting sclerosing agents to stop bleeding or taking a biopsy. The channel passing through the scope lets to wash the area or pass the instruments such as biopsy forceps or metal clips to squeeze a bleeding vessel. The same channel is also useful to aspirate the liquid contents in the lumen to clean the visualization area.

How to do a Gastroscopy?

Anaesthetizing of throat

Before starting the procedure, the back of the mouth and throat is drugged with a local anaesthetic spray. This agent is applied to this area by spraying. The patient is then placed on his left side.


With intravenous sedoanalgesia drugs, the patient is put to sleep under close follow-up. The patient who is put to sleep with sedoanalgesia is followed for partial oxygen pressure with a pulse oximeter device from the finger. At the same time, the patient’s heart rate is monitored on the screen. A diagnostic gastroscopy process takes between 2 and 4 minutes.

What is done during the process

During gastroscopy operations, biopsy fragments are taken from the corpus or antrum which are parts of the stomach, for pathological examination with a small device called biopsy forceps that are passed through the endoscopy channel. After pathological examination of biopsies, the presence of helicobacter pylori bacteria on the surface of the stomach, the severity of gastritis, and the presence of intestinal metaplasia are generally evaluated.

The first part of the duodenum area is called bulbous Bulbus is the region where the upper gastrointestinal system bleeding most commonly occurs. The active bleeding in patients can be stopped during gastroscopy with a method called sclerotherapy. The sclerotherapy process is performed by injecting sclerotherapy solution around the bleeding area and in the middle through the sclerotherapy needle passed through the channel of the device.

Many other therapeutic procedures can be performed easily during the gastroscopy procedure. The removal of polyps in the stomach, the disintegration, and the removal of petrified foods called a bezoar, which occurs over time in the stomach, the removal of foreign substances accidentally swallowed (such as a pin, battery) are examples.

Considerations After The Procedure

According to the drugs given for sedoanalgesia, the patient’s recovery awakening period may differ. In some sedation drugs, the recovery time can take up to 30 to 60 minutes. In some of the patients, the awakening will be much quicker. However, in any case, these patients are strongly advised not to drive during that whole day, not to do signed in work, or not to arrange jobs that require responsibility.

Nursing mothers

It is recommended that they do not breastfeed for six hours after the procedure. The first milk after 6 hours should be drained and spilled with the pump, not given to the baby. Then breastfeeding can be started. Milk can be collected with the pump before the procedure and given to the baby after the procedure.
