Gastroscopy and colonoscopy
Gastroscopy is an endoscopic examination of the upper gastrointestinal tract: esophagus, stomach and duodenum, involving the insertion of a flexible tube equipped with a light source and a system transmitting an image from the inside of the body. The test takes about 5-10 minutes and is performed under local or throat intravenous anesthesia.
Colonoscopy is an endoscopic examination of the large intestine – that is, the lower gastrointestinal tract, consisting in the introduction of a special speculum through the anus with a camera and the image being sent outside.
