Endoscopy is the process of examining the hollow organs with visual or direct vision tools. Endoscopy is a general designation. According to the organ examined the name changes and is done by targeting different segments of the digestive system. However, when endoscopy is commonly used in the community, Gastroscopy is performed to see the esophagus-stomach-duodenum.
Gastroscopy is the examination of the esophagus-stomach-duodenum. Some also describe this as an Upper GIS (upper gastrointestinal tract) endoscopy. Gastroscopy is also progressed by the endoscope or the gastroscope, which is known as the duodenum, orally, with a light and flexible device with a camera at the end.
Colonoscopy is an endoscopy for large intestines. In colonoscopy, aneurysm is inserted through the endoscopy which is flexible and longer than the gastroscopy and the diseases related to the large intestines are investigated by observing a distance of approximately 70-120 cm. If an anterior endoscopic examination is performed in the last 30-50 cm of the large intestine, this is called flexible rectosigmoidoscopy.
It is very important for the endoscopic examination that the organ to be examined is cleaned. 8 hours of fasting is sufficient for gastroscopy. A few days of preparation is required for colonoscopy. The large intestines should be completely empty and clean. For this, a special program is applied and some drugs are used. You will be informed about this preparation when you make an appointment.
