Gastroendoskopie

Gastroendoskopie, commonly known as an endoscopy, is a medical procedure used to examine the interior of the upper gastrointestinal tract. This tract includes the esophagus, stomach, and the first part of the small intestine, known as the duodenum. The procedure involves inserting a long, flexible tube called an endoscope into the body. This endoscope has a light source and a camera attached to its tip, which transmits images to a monitor, allowing the physician to visualize the lining of these organs.

The primary purpose of a gastroendoskopie is diagnostic. It helps identify the cause of symptoms such as persistent heartburn, difficulty swallowing, abdominal pain, nausea, vomiting, or unexplained weight loss. Through the endoscope, doctors can detect abnormalities like inflammation, ulcers, polyps, or tumors. In addition to visualization, the endoscope can be used to perform biopsies, where small tissue samples are taken for further laboratory analysis. Therapeutic interventions can also be carried out during an endoscopy, such as stopping bleeding, widening narrowed areas, or removing polyps.

Before the procedure, patients are typically required to fast for several hours to ensure the upper gastrointestinal tract is empty. Sedation is often administered to make the patient comfortable and relaxed. The procedure itself usually takes between 15 to 30 minutes. Following the gastroendoskopie, patients are monitored until the effects of sedation wear off. Recovery is generally quick, with most people able to resume their normal activities the same day, though some may experience a sore throat.
