If the patient suffers from persisting stomach aches, vomiting, bleeding or anemia, in order to diagnose him/her, the internist may prescribe an endoscopic examination. The endoscope can detect minor, otherwise unnoticeable abnormalities in the gastrointestinal tract. Upon request, we can perform the examination in anesthesia. It usually does not have any side effects, on rare occasions it causes throat dryness, coughing or mild bleeding.
The endoscope is a flexible tool made of optical fiber with a small camera at the end. It visualizes the esophagus, the stomach and the small intestine on a screen, enabling to evaluate the condition of their mucous membrane.
Before the treatment the pharynx is partly anesthetized then a tube is inserted towards the direction of the stomach. The specialist pumps some air into the stomach to ensure visibility during imaging. Through the tube the optical fiber is led down to the area subject to examination.
Endoscopy provides an opportunity to take tissue samples painlessly. The same method is suitable for other therapeutic interventions such as the treatment of varicosity (swelling of the veins) in the stomach.
At the end of the interventions the tube is carefully removed from the pharynx. The whole process takes less than 30 minutes but in case of a therapy it could take longer. The patient can leave after a short rest.
