Endoscopy allows a visual examination of internal organs and body parts without invasive exploratory surgery. One of the main functions of endoscopy is foreign body removal. It was first described in the early 1800's, but it was not until the late 1800's that optical lenses were developed which could be used in viewing devices and endoscopy could start to be used.

Endoscopy is performed with either a rigid or flexible fiberoptic instrument. Flexible endoscopes such as those used in the examination of the stomach consist of a long, flexible insertion tube with a bending tip at the end that enters the body, an eyepiece, and a control section. The tip of the endoscope is manipulated using a control knob in the hand piece.

In addition to the fiber bundles which provide the light source, two channels are present within the endoscope. One channel permits various endoscopic tools to be passed, fluids to be suctioned, or samples taken. The other allows air or water to be passed into the stomach/intestine to insufflate (inject air into the area), or wash away mucus from the viewing port.
