Using a fiber-optic endoscope, your doctor can view your esophagus, stomach and part of your duodenum.
Endoscopes are minimally invasive and can be inserted into the openings of the body such as the mouth or anus.
Alternatively, they can be inserted into small incisions, for instance, in the knee or abdomen. Surgery completed through a small incision and assisted with special instruments, such as the endoscope, is called keyhole.
Because modern endoscopy has relatively few risks, delivers detailed images, and is quick to carry out, it has proven incredibly useful in many areas of medicine. Today, millions of endoscopies are carried out each year.
