What is an Endoscopy?


An endoscopy is a non-surgical procedure that can be used for an examination of the digestive tract, as well as other organs including the lungs, bladder, uterus, and so on. The procedure is performed using a flexible tube that is inserted via an orifice or incision to give your doctor a clear view of internal structures. The tube, which is called an endoscope, has a light and tiny camera that sends detailed images to a TV monitor.

What are the types of Endoscopy?

There are different types of endoscopies, depending on the structure to be examined or treated. These can include:

  • Endoscopies for the GI tract such as esophagogastroduodenoscopy to examine the esophagus or stomach, enteroscopy for the small intestine, colonoscopy for the colon or large intestine, and rectoscopy for the bile duct and rectum.
  • Endoscopies for the respiratory tract including rhinoscopy and bronchoscopy for the nose and lower respiratory tract respectively.
  • Gynoscopy for examination of the female reproductive tract, including colposcopy, hysteroscopy, and falloposcopy, for examination of the cervix, uterus, and fallopian tubes respectively.

Additionally, endoscopic procedures may also be used to examine structures of the ear (otoscopy) and the urinary tract (cystoscopy). For some types of endoscopy, the tube must be inserted via a small incision, as in the case of laparoscopy to examine the abdominal or pelvic cavity, arthroscopy to examine joint interiors, and thoracoscopy to examine organs in the chest cavity.

Today, gastroenterologists also use an advanced form of endoscopy known as capsule endoscopy, in which a wireless camera is fitted into a capsule that can be swallowed, recording extensive data while travelling through the digestive tract. It is mainly used for the examination of the small intestinal mucosa and is passed out of the body with 24 to 48 hours.

Preparation for Endoscopy

Your doctor will give you personalized instructions on how to prepare depending on the type of procedure required. In most cases, these requirements are fairly standardized.

Before the Procedure

Upper GI endoscopy will only require fasting for 6 to 8 hours before the procedure, while a colonoscopy will require administration of laxatives to clear the colon of faeces before the procedure.

During the Procedure

In most endoscopic procedures, patients receive a sedative to prevent discomfort. This may be administered via injection and promotes relaxation and induces light sleep. You can expect to wake up within an hour with almost no recollection of the procedure.

After the Procedure

The effects of sedatives that are administered during the procedure can last for some time after the procedure, making it important to avoid driving or use of any machinery that can pose a risk of injury to yourself or others. Make arrangements to have someone drive you home after the procedure.
