Endoscopy and Colonoscopy
Endoscopy is a procedure that lets your doctor look inside your body. It uses an instrument called an endoscope, or scope for short. Scopes have a tiny camera attached to a long, thin tube. The doctor moves it through a body passageway or opening to see inside an organ. Sometimes scopes are used for surgery, such as for removing polyps from the colon.
There are many different kinds of endoscopy. Here are the names of some of them and where they look.
- Arthroscopy: joints
- Bronchoscopy: lungs
- Colonoscopy and sigmoidoscopy: large intestine
- Cystoscopy and ureteroscopy: urinary system
- Laparoscopy: abdomen or pelvis
- Upper gastrointestinal endoscopy: esophagus and stomach
Colonoscopy is a procedure that lets your doctor look inside your entire large intestine. It uses an instrument called a colonoscope, or scope for short. Scopes have a tiny camera attached to a long, thin tube. The procedure lets your doctor see things such as inflamed tissue, abnormal growths, and ulcers.
Your doctor may recommend a colonoscopy for a number of reasons:
- To look for early signs of cancer in the colon and rectum
- To look for causes of unexplained changes in bowel habits
- To evaluate symptoms like abdominal pain, rectal bleeding, and weight loss
Your doctor can also remove polyps from your colon during a colonoscopy.
