According to the American Cancer Society, Colorectal cancer is one of the most preventable yet deadliest cancers if not caught early. The good news? Screening options have expanded beyond the traditional colonoscopy, giving patients and providers multiple ways to detect and prevent cancer. But not all screening tools are created equal.
At Vantage Surgical Solutions, we believe that knowledge is power—especially when it comes to choosing the right GI screening tool for each patient. To help hospitals, providers, and patients make informed decisions, we’ve compared the most commonly used screening methods:
✅ Colonoscopy – The Gold Standard
✅ FIT (Fecal Immunochemical Test) – A simple, at-home test
✅ gFOBT (Guaiac-Based Fecal Occult Blood Test) – An older stool-based test
✅ Cologuard – DNA-based stool test
✅ PillCam (Capsule Endoscopy) – A newer, swallowable camera

Colonoscopy: The Gold Standard
Best for: High-risk patients, those with a personal or family history of colorectal cancer, and anyone looking for the most thorough screening.
How it Works: A flexible camera is inserted into the colon to detect and remove benign, pre-cancerous and cancerous growths in one procedure.
Pros:
✔ Most effective—detects 95% of colorectal cancers and precancerous growths
✔ Aids in the diagnosis of gastrointestinal conditions
✔ Only required once every 10 years for average-risk individuals
Cons:
⚠ Requires bowel prep and sedation
⚠ Slight risk of complications (bleeding, perforation, or anesthesia risks)
⚠ Some patients hesitate due to discomfort or fear
Bottom Line: Colonoscopy is the most effective preventative screening because it doesn’t just detect cancer—it removes pre-cancerous growths before they can become life-threatening.

FIT (Fecal Immunochemical Test): Convenient and Affordable
Best for: Average-risk individuals who prefer a non-invasive option.
How it Works: A stool sample is tested for hidden blood (a potential sign of colorectal cancer).
Pros:
✔ Non-invasive, done at home
✔ No dietary restrictions or bowel prep
✔ More sensitive than older stool-based tests (gFOBT)
✔ Affordable and widely available
Cons:
⚠ Needs to be repeated yearly
⚠ Cannot detect polyps—only signs of cancer
⚠ If positive, a colonoscopy is required for further diagnosis
Bottom Line: A great first step in screening, but patients who test positive still need a colonoscopy to confirm results.

gFOBT (Guaiac-Based Fecal Occult Blood Test): The Traditional Stool Test
Best for: Patients with limited access to newer tests.
How it Works: Detects hidden blood in stool using a chemical reaction.
Pros:
✔ Inexpensive, widely available
✔ Non-invasive and home-based
Cons:
⚠ Less sensitive than FIT (can miss cancers)
⚠ Requires dietary restrictions (no red meat, certain veggies, or medications before the test)
⚠ Higher false positives and false negatives
⚠ If positive, a colonoscopy is required
Bottom Line: An older test that is being replaced by FIT, which is more accurate and easier to use.

Cologuard: DNA-Based Stool Testing
Best for: Patients who want a more advanced stool test but are not high-risk.
How it Works: Tests stool DNA and blood for signs of colorectal cancer or advanced polyps.
Pros:
✔ More sensitive than FIT—detects 92% of colorectal cancers
✔ Non-invasive, done at home
✔ No dietary restrictions or bowel prep
Cons:
⚠ Still less effective than colonoscopy—misses 8% of cancers and over 40% of pre-cancerous polyps
⚠ Higher false positive rate than FIT (many patients still require colonoscopy)
⚠ Expensive compared to other stool tests
⚠ Not recommended for high-risk patients
Bottom Line: While convenient, it is not a replacement for colonoscopy unless the patient has a medial necessity for an alternate option.

PillCam (Capsule Endoscopy): The Swallowable Camera
Best for: Patients who cannot undergo colonoscopy due to medical conditions or past complications.
How it Works: A pill-sized camera captures images of the digestive tract as it moves through the body.
Pros:
✔ Non-invasive—no sedation required
✔ Can visualize parts of the small intestine that colonoscopy can’t reach
✔ Good alternative for patients who cannot tolerate a colonoscopy
Cons:
⚠ Not a first-line screening tool—usually used for patients who couldn’t complete a colonoscopy
⚠ Does not allow for polyp removal—if something is found, a colonoscopy is still needed
⚠ Expensive and not always covered by insurance
Bottom Line: A helpful tool for patients with medical necessity for an alternative to colonoscopy, but not a primary screening method for colorectal cancer.
Which Screening Tool is Right For You?
The Vantage Advantage: Expanding Access to Life-Saving Screenings
For rural hospitals, colonoscopy access is the biggest barrier to colorectal cancer prevention. Many patients rely on stool tests, but when a FIT or Cologuard result comes back positive, they still need a colonoscopy—and too many rural patients don’t get that follow-up care.
At Vantage Surgical Solutions, we bring GI services directly to rural hospitals, making it possible for patients to get the screenings they need close to home.
✔ One OR day per month can keep patients in the community for their follow-up colonoscopy.
✔ No need for a full-time GI specialist—our mobile solution makes it simple.
✔ Improve patient outcomes and hospital revenue with expanded GI services.
March is Colorectal Cancer Awareness Month—encourage your friends and family to get screened starting at age 45. It could save their life—or yours.
