What is Endoscopy?

EndoscopeAn endoscopy is a procedure that uses an endoscope to examine the inside a person’s digestive tract. An endoscope is a thin, tube-like instrument with a light and a camera lens at the end. It also can have a tool that removes tissue to be examined under a microscope for signs of disease.

Types of Endoscopies

Below are the different types of endoscopies performed at Christian Hospital.

Upper Endoscopy
An upper endoscopy is an endoscopy procedure that is passed through the mouth, throat and esophagus and views and examines only the upper part of the intestine.

A colonoscopy is an endoscopy procedure that is passed through the rectum to examine the large intestine or colon.

A sigmoidoscopy is an endoscopy procedure that is passed through the rectum to examine the sigmoid colon. This type of diagnostic test is used to screen for colorectal cancer.

Endoscopic Retrograde Cholangiopancreaticography (ERCP)
An ERCP is an endoscopy procedure that examines the pancreas and gallbladder.

Endoscopic Ultrasound (EUS)
Endoscopic Ultrasound is a minimally invasive diagnostic test that combines the technologies of endoscopy and ultrasound to diagnose conditions in the chest and abdomen. Applications for EUS include tumor staging (determining the severity of cancer based on the size and reach of the original tumor) in areas of the body that are difficult to see by standard endoscopic evaluation, including:

  • Esophagus
  • Stomach 
  • Rectum
  • Pancreas and bile ducts 
  • Gastrointestinal tract 

Besides diagnosis, EUS also has therapeutic (treatment) purposes. For example, biliary duct cannulation (a tube inserted into the body to either draw off excess fluid or introduce medicine) that is not successful during endoscopic retrograde cholangiogram (X-ray of bile duct) can be managed with an EUS-guided cholangiogram.
