Colonoscopy
Colonoscopy is a completely painless procedure in which a flexible, tubular instrument (colonoscope) uses an electronic camera to observe the inside of the entire large intestine, including a short section of the small intestine from the inside and check for pathological changes. If necessary, tissue samples can also be taken painlessly and polyps completely removed as possible preliminary stages of cancer that are still benign. Subsequently the tissue samples are subjected to a fine-tissue analysis. The coloscopy is carried out with the patient fasting and after colonic irrigation. Before this examination a detailed pre-examination discussion is held with the doctor.
