Gastroscopy is an examination of the esophagus, stomach and duodenum. It determines the true cause of problems, that is, pathological (malignant) changes so that they could be identified sooner and treated properly.
What are the reasons for a gastroscopy examination?
- Heartburn, nausea, vomiting
- Difficulties with swallowing, a discomfort in the upper part of the abdomen
- Blood in vomit or a black stool
- Removing a foreign object (swallowed object)
- Examining the healing process or a progression of previously diagnosed polyps or ulcers
- Loss of appetite or weight loss
- Unspecified anemia
- Palpable mass in the abdomen
How is the procedure done?
In order to perform the examination, a flexible optical instrument (endoscope) is inserted through the mouth into the esophagus, stomach and duodenum. The process of pushing air prevents from disturbing the digestive system so that the malignant pathological changes can be easily detected. If it is necessary, during the examination small tissue samples could be taken using small pincers, which could be sent for a further histopathological analysis.
What are the necessary preparations?
In order to properly examine the upper digestive system, it is required that it has no food remains. Hence, you should not eat or drink on the day of the examination, which means you should not consummate food or drinks at least six hours before the procedure.
What are the advantages of the procedure?
Pathological changes are detected and diagnosed with greater certainty via this examination and a histopathological analysis of the tissue sample.
What should you pay attention to?
If you were given pharyngeal anesthesia or a sedative injection, you should not eat or drink at least one hour after the examination. When it comes to consummating food and other rules afterwards, you should adhere to the advice of your physician. If you experience pain or other problems (such as dizziness, nausea, blood vomiting), consult your physician immediately.
