Like most technologies, endoscopy is constantly advancing. Newer generations of endoscopes use high-definition imaging to create images in incredible detail. Innovative techniques also combine endoscopy with imaging technology or surgical procedures.
Here are some examples of the latest endoscopy technologies.
Capsule endoscopy
A revolutionary procedure known as a capsule endoscopy may be used when other tests aren’t conclusive. During a capsule endoscopy, you swallow a small pill with a tiny camera inside. The capsule passes through your digestive tract, without any discomfort to you, and creates thousands of images of the intestines as it moves through.
Endoscopic retrograde cholangiopancreatography (ERCP)
ERCP combines X-rays with upper GI endoscopy to diagnose or treat problems with the bile and pancreatic ducts.
Chromoendoscopy
Chromoendoscopy is a technique that uses a specialized stain or dye on the lining of the intestine during an endoscopy procedure. The dye helps the doctor better visualize if there’s anything abnormal on the intestinal lining.
Endoscopic ultrasound (EUS)
EUS uses an ultrasound in conjunction with an endoscopy. This allows doctors to see organs and other structures that aren’t usually visible during a regular endoscopy. A thin needle can then be inserted into the organ or structure to retrieve some tissue for viewing under a microscope. This procedure is called fine needle aspiration.
Endoscopic mucosal resection (EMR)
EMR is a technique used to help doctors remove cancerous tissue in the digestive tract. In EMR, a needle is passed through the endoscope to inject a liquid underneath the abnormal tissue. This helps separate the cancerous tissue from the other layers so it can be more easily removed.
Narrow band imaging (NBI)
NBI uses a special filter to help create more contrast between vessels and the mucosa. The mucosa is the inner lining of the digestive tract.
