Gastroscopy (esophagogastroduodenoscopy)

This is the endoscopy of the esophagus, stomach and the upper part of the small intestine.

When is this procedure done?
This procedure can clarify disorders and discomfort of the upper digestive tract. This can include difficulties swallowing, pain behind the breastbone, acid reflux, abdominal fullness and bloating, nausea, unexplained vomiting and the clarification of vomiting blood as well as black stool. Chronic deficiencies such as iron deficiency or vitamin deficiency can also be clarified via diagnostic investigation of the upper gastrointestinal tract.

What happens during a gastroscopy?
Prior to the procedure, we meet with you for a medical consultation during which we will explain the procedure and discuss your individual requests and risk factors. On the day of the procedure you must not eat any solid foods nor drink any liquids. The gastroscopy can be carried out while you are in a twilight sleep or while a topical anesthesia is applied to the oropharynx, depending on your preference. The endoscope is inserted via the mouth and advanced all the way to the duodenum. Applying insufflation to the digestive tract, the stomach unfolds, enabling a good assessment of the mucous membrane. Depending on the medical issue and the findings resulting from it, tissue samples may be retrieved, polyps may be removed, vessels may be cauterized (argon plasma coagulation), and larger ulcers may be treated. A gastroscopy of the upper digestive tracts takes about 10-15 minutes; if treatment is required, the procedure may take longer. During the twilight sleep phase, you will be monitored continuously. After waking up you will quickly feel fit and yourself again. However, we must point out that for 24 hours following local anesthesia your reaction time might be affected and you must not operate a vehicle. Prior to the procedure, please arrange for a person you trust to pick you up from our practice; if possible, you should also not be alone at home after the procedure.
