Endoscopy is a general term for diagnostic procedures that utilize various endoscopic instruments. The procedure usually refers to the examination of the upper digestive tract and is therefore sometimes called gastroscopy.
However, endoscopic procedures are named according to the organ being examined.
For example, an examination of the lower digestive tract is called colonoscopy and is performed using a colonoscope.
An upper gastrointestinal endoscopy typically involves introducing a long, flexible tube (endoscope) into the esophagus through the mouth.
A small camera at the tip of the device enables examination of the esophagus, stomach, and the upper part of the small intestine (the duodenum).
