two procedures that perform essentially the same function, with the name of the particular procedure being determined by the location that is being examined.
Endoscopy and bronchoscopy are primarily diagnostic procedures. An endoscope is used to examine the stomach, small intestine, and large intestine. A bronchoscope is used for airway examination, primarily the trachea and lungs. These procedures can also be therapeutic, as endoscopy and bronchoscopy can be used to non-surgically remove foreign bodies and take internal biopsies for further diagnosis.
The procedures involve the use of a magnifying scope connected to a light source that allows the surgeon to look at the actual internal organs that may have disease or injury not easily determined using other diagnostic methods.
