This procedure uses different approaches to look at internal organs and tissues.
An endoscopy is a procedure that’s performed to look inside the body at a specific organ to detect a range of conditions and diseases.
Your doctor will insert an endoscope into your body through an entryway (mouth, anus, vagina, nose, or urethra) or through an incision, notes MedlinePlus.
What Is an Endoscope?
An endoscope is an instrument designed to look at different parts of the body. The instrument comes in different shapes and lengths, according to Cancer.Net.
Most are thin, hollow, flexible tubes that have a light attached. Some also come with a tiny video camera attached that transmits images to a computer.
The newest versions of endoscopes, known as capsule endoscopes, are small enough to be swallowed and send images wirelessly to a computer.
