This is a test that uses ultrasound waves. It allows the doctor to see the depth of unusual areas of tissue much better than typical exams. A small flexible tube is used to examine the area.

This means that a very small needle will be inserted through the flexible tube to sample cells in the unusual area of the esophagus (food pipe), stomach, lungs, bowel or pancreas noticed in previous tests or x-rays. You will not feel the needle when the sample is taken.
