Colonoscopy is an outpatient procedure in which your large bowel (colon and rectum) is examined. We perform the procedure to diagnose and treat, when possible, certain diseases of the lower gastrointestinal (GI) tract, which includes the rectum and colonoscopy. Sigmoidoscopy is examining Rectum & sigmoid colon.
A colonoscopy may be used to screen for colon cancer and evaluate many problems, including:
- Abdominal pain
- Anemia (low red blood cells)
- Blood in the stool
- Change in bowel habits
- Unexplained weight loss
Endoscopy may also be done to:
- Bleeding from diverticula or other lesions can be treated by injecting medicine around them or by applying heat to cauterize -- or seal -- them.
- Polyps, some of which may be cancerous, can be removed using a lasso-like device through the colonoscope.
- Narrowed areas or strictures can often be dilated using a balloon.
