Colonoscopy

Preventative (Screening) Colonoscopy

A colonoscopy is an examination of the entire colon (large intestine) using a long, thin, flexible tube (colonoscope) with a camera on the tip. The most common goal is an effort to prevent colon cancer. Without any screening colonoscopy, about one in twenty people will develop colon cancer. A preventive colonoscopy (sometimes referred to as a screening colonoscopy) is performed on a patient who is asymptomatic (no gastrointestinal symptoms either past or present), is 50 years of age or older, or has no personal or family history of colon polyps and/or colon cancer. 

Diagnostic Colonoscopy

A colonoscopy is an examination of the entire colon (large intestine) using a long, thin, flexible tube (colonoscope) with a camera on the tip. The most common goal is an effort to prevent colon cancer. Without any screening colonoscopy, about one in twenty people will develop colon cancer. A diagnostic colonoscopy is performed on a patient who has gastrointestinal symptoms (e.g. rectal bleeding, abdominal pain, diarrhea) or who has past and/or present polyps or gastrointestinal disease (e.g. Crohn’s Colitis, etc.). If polyps are found during a screening colonoscopy, most insurance carriers re-categorize the screening colonoscopy as a diagnostic colonoscopy (and your screening benefit may no longer apply). 

 

Upper Endoscopy

An upper endoscopy or EGD (esophagogastroduodenoscopy) is a test performed with an endoscope, which is a long, flexible tube that is thinner than most food you swallow. The test allows your physician to examine the lining of the esophagus, stomach and duodenum (the first portion of the small intestine). Doctors perform an upper endoscopy to help find the cause of symptoms such as persistent heartburn, bleeding, nausea and vomiting, and problems swallowing. An EGD is also performed to diagnose GERD (gastroesophageal reflux disease), ulcers, Celiac Disease, or Barrett’s Esophagus.

 

Flexible Sigmoidoscopy

A flexible sigmoidoscopy is an examination of the lower portion of the colon (sigmoid) using a colonoscope. This test is indicated only for specific situations and is not the recommended test for colon cancer screening.
