Endoscopy is a minimally invasive technique used to examine the internal organs of the body. It involves the insertion of a long, thin tube (endoscope) into the body through natural openings such as the mouth, anus, or through a small incision, such as in the knee or abdomen.

An endoscope has a tiny camera and a light on the end, which allows doctors to view the inside of the body in detail. Endoscopy can also be used for imaging, surgery, and other tasks. Endoscopy has become one of the most commonly used medical procedures.

It is a safe, effective, and quick way to gather detailed images of the internal organs. An estimated 75 million Trusted Source endoscopies are carried out each year in the United States.

Different Types of Endoscopy

There are various types of endoscopy. The most common are gastroscopy and colonoscopy. During a gastroscopy, an endoscope is inserted into the esophagus, stomach, and the first part of the small intestine.

During a colonoscopy, an endoscope is inserted into the large intestine, or colon. During both procedures, the doctor can look for any abnormalities such as ulcers, polyps, or cancer. Other types of endoscopy include bronchoscopy, laparoscopy, cystoscopy, and arthroscopy.

During a bronchoscopy, an endoscope is inserted into the windpipe to take a look at the lungs. During a laparoscopy, an endoscope is inserted into the abdomen to look at the internal organs.

During a cystoscopy, an endoscope is inserted into the bladder to look for abnormalities. During an arthroscopy, an endoscope is inserted into a joint to diagnose any joint problems.

The general procedure for an endoscopy is as follows:

  • Patients are usually asked to fast for at least 8 hours before the procedure.
  • The patient may be given a mild sedative to reduce any discomfort.
  • The patient is placed in a comfortable position on a bed.
  • The endoscope is carefully inserted into the body.
  • The doctor will then take images of the internal organs using a miniature camera.
  • The procedure usually takes between 30 minutes and 2 hours.
  • The patient can usually go home soon afterwards.

Although endoscopy is generally safe, there is a small risk of minor complications such as bleeding, infection, or reaction to the sedative. However, these risks are rare and the benefits of endoscopy usually outweigh the risks.

How to Prepare for an Endoscopy

Preparing for an endoscopy can seem daunting, but it is important to understand what is required to ensure the best possible outcome. An endoscopy does not require an overnight stay in the hospital and usually only takes around 1 hour to complete.

The doctor will provide instructions about the preparation for the procedure, so it is important to follow their advice to ensure the best results. For many types of endoscopy, the individual needs to fast for around 12 hours, though this varies based on the type.

It is important to stop eating or drinking the night before the procedure, or the doctor may advise to reduce the intake of food and drink. It is important to follow this advice as it can help to reduce the risk of complications.

For procedures investigating the gut, laxatives may be taken the night before to clear the system. This will help to make the exam easier and more comfortable. In addition, it is important to avoid taking any medications (including supplements) the day before the procedure.

A doctor will conduct an examination before the endoscopy. It is important to mention all current medications (including supplements) and any previous procedures or medical conditions that may be relevant.

The doctor may also need to know of any allergies or sensitivities. It is important to mention any of these to ensure the safest and most effective procedure is carried out.
