Gastroscopy

A gastroscopy, also known as an endoscopy is a procedure performed by a doctor, a well-trained subspecialist who uses the endoscope to diagnose and, in some cases, treat problems of the upper digestive system.

The endoscope is a long, thin, flexible tube with a tiny video camera and light on the end.

By adjusting the various controls on the endoscope, the doctor can safely guide the instrument to carefully examine the inside lining of the upper digestive system.
