An endoscopy is a medical way to look inside the body.

Doctors use a special tool called an endoscope for this task. This tool is a tube that goes directly into a hollow organ. It is different from other ways doctors take pictures of the body. Most often, the word refers to looking at the upper digestive tract. This specific test is called an esophagogastroduodenoscopy.

Doctors or surgeons perform these procedures on many different parts of a person.

How does the tool work during a procedure? The endoscope enters the body to examine the inside of an organ. A doctor might use a cutting tool at the tip. This allows them to perform minor tasks like a biopsy. A biopsy is when a doctor takes a tiny piece of tissue to check it. They can also use the tool to remove a polyp. They might even use it to take out a stuck object.

The tool can even help by cauterizing a bleeding vessel.

People have been finding ways to see inside the body for a long time. Adolf Kussmaul was once fascinated by sword swallowers. He saw them put swords down their throats without gagging. This gave him an idea for a hollow tube for observation. Later, engineers had to figure out how to add light. In 1855, Charles Chevalier used the term endoscope for the first time. In 1894, John Macintyre developed a self-illuminated version in Scotland. He used it to study the larynx, which is part of the throat.

There are many different types of endoscopy for different body parts. Doctors can look at the stomach, small intestine, or large intestine. A colonoscopy looks at the colon, while an enteroscopy looks at the small intestine. They can also look at the nose or the lungs. Some tools look at the ears or the bladder. Even the reproductive system can be checked with this method.

There are also tools for looking inside joints or the chest.

Endoscopy is not just for doctors in hospitals. People use similar tools called borescopes for non-medical work. These help inspect complex technical systems from the inside. Architects even use a type of endoscopy to see scale models. This helps them plan buildings and cities before they are built. Bomb disposal teams also use them to check for dangerous devices. Law enforcement can use them to look through very tight spaces. It is a helpful tool in many different jobs.
