Gastroscopy

Gastroscopy (EGD - esophagogastroduodenoscopy, fibrogastroscopy, endoscopic examination of the stomach and duodenum ) is the most accurate diagnostic study that allows the physician endoscopist not only to examine the lining of the esophagus, stomach and duodenum, but also to perform more accurate diagnostic manipulation:

• staining of the mucosa with a special dye to diagnose changes, including precancerous (chromoendoscopy);
• to study the vascular pattern using narrow-band modes ( NBI ) on the monitor with high resolution;
• establish the presence of infection (Helicobacter pylori) and to take small pieces of material mucosa for histological examination (polypositional biopsy).
