With an endoscope, a doctor can look inside parts of the body that have openings, like the bowel, lungs, vagina or bladder. Endoscopes usually have a little light and a camera. Depending on the type of examination, an endoscope could be a short, stiff pipe that enables inspection of the bladder or vagina. Or it can be a long flexible tube that can be inserted into, for example, the stomach or bowel.
