One of the important studies in gastroenterology is gastroscopy. Simplicity, painlessness and high accuracy of the results obtained make gastroscopy indispensable in the diagnosis of diseases of the digestive system.

Gastroscopy is an endoscopic examination of the digestive tract, which allows you to study the inner wall of the stomach. It is currently the reference study for the esophagus, stomach and duodenum. Gives the opportunity to highlight any foci and perform a biopsy (removal of a fragment of tissue for study under a microscope).

Fibrogastroscopy as a method of examining the state of the gastrointestinal tract has its advantages. This examination can be performed at the top top clinics in Switzerland.

Indications for gastroscopy

Why is a gastroscopy performed?

There are various situations in which a gastroscopy can be useful. It can be long-term diffuse symptoms or a very specific suspicion of a disease.

A gastroscopy may be performed for symptoms such as these:

If bleeding is suspected in esophageal varices, gastroscopy is very important for gastric ulcers (peptic ulcers) or cancer.

What diseases can a gastroscopy detect?

 Gastroscopy can detect inflammation of the gastric mucosa (gastritis) ,

  • gastric or duodenal ulcers,
  • changes in the esophageal mucosa (Barrett's esophagus is a special condition characterized by metaplasia of the esophageal squamous epithelium (replacing it with cylindrical epithelium like intestinal epithelium). Such a picture is observed in the prolonged course of gastroesophageal reflux disease and is one of its most serious complications),
  • esophageal varices
  • cancers of the esophagus and upper digestive tract, such as esophageal cancer and stomach cancer, are diagnosed and sometimes even treated.

Gastroscopy is a very effective examination method that has almost completely replaced X-rays. You will get a good overview of the condition of the esophagus, stomach and duodenum.
  • You can take various tissue samples and take photographs through the gastroscope. Videography is also possible so that you can examine the mucosa on the screen and record it on video. The recording can be useful for later comparison, for example, after treatment has been completed. cancer.
  • fo Procedures that can be performed with a gastroscope:
    • Narrowings can be dilated.
    • Tissue samples can be taken.
    • Polyps can be removed.
    • The lining of the stomach can be removed.
    • Bleeding can be stopped.
    • Endoscopic ultrasound can be performed.
    • Gallstones can be removed from the bile ducts.
