What is gastroscopy?
Gastroscopy (EGDS, FEGDS, FGS, esophagogastroduodenoscopy) is an endoscopic examination of the upper gastrointestinal tract using an endoscope, which is performed by an endoscopist. During gastroscopy, the doctor examines the esophagus, stomach and duodenum (the initial part of the small intestine) from the inside.
Gastroscopy (advantages of the method).
Gastroscopy is the "gold" standard (the best method) for the diagnosis of inflammatory, erosive, ulcerative, precancerous and neoplastic diseases of the esophagus, stomach and duodenum 12.
Any other methods for diagnosing these organs do not have such information content and accuracy.
A modern endoscope is a highly sophisticated high-tech device that allows a qualified endoscopist to see the image with optical magnification and examine everything in great detail. After all, any changes in color and surface, even a few millimeters in size, are very important for detecting not only the disease itself, but also its first signs.
During gastroscopy, a biopsy is performed, followed by histology, if necessary, examine the cells under a microscope and make a diagnosis at the cellular level, additionally conduct an analysis for the bacteria Helicobacter pylori (text Helicobacter), which is not only the cause of erosive and ulcerative lesions of the stomach and gastritis, but also for many years being in the stomach can lead to more serious consequences.
