Colonoscopy in New Jersey | Hackensack Meridian Health   

What is a Colonoscopy?

A colonoscopy is a simple outpatient exam that helps uncover any potential digestive issues, such as Colitis, Diverticulosis and colon cancer.

A colonoscopy visually examines your entire colon using a long flexible tube with a small camera at the end. During the procedure, a video monitor in the exam room shows the images captured on camera. The physician watches the monitor and may also remove tissue samples (biopsies) or polyps for further tests.

What to Expect

To allow for a thorough exam, your lower colon should be clean. This means you may only drink clear liquids, along with taking laxatives or an enema the day before the procedure.

Bloating and bowel distension are common and should only last about 30 to 60 minutes after the procedure. If your physician removes biopsies or polyps during the exam, you may experience some spotting of blood afterward. However, this is rarely serious. You should not drive or operate machinery for the remainder of the exam day.

Your physician will be able to provide you with additional information before your exam day.

How to Prepare for a Colonoscopy

Why are Colorectal Screenings Important?

The American Cancer Society recommends regular screenings starting at the age of 45. Colorectal cancer can often go undetected without symptoms. Early detection is critical to effective treatment.

You may be due for a colonoscopy if any of the following apply:

  • You are 45 or older
  • It has been 10 years since your last colonoscopy (5 years if you are considered at a higher risk)
  • You had polyps removed during your colonoscopy (speak to your doctor about your next visit)
  • Family history of colorectal cancer
  • Familial adenomatous polyposis (FAP) or Lynch syndrome
  • You have inflammatory bowel disease

Why It's Done

A colonoscopy is a preventative measure to help detect potential issues at an early stage, even before you may experience any symptoms.

It is also helpful in allowing your physician to diagnose the cause of certain symptoms you may already be experiencing, such as:

  • Bleeding
  • Diarrhea
  • Lower abdominal pain
  • Abnormal x-ray findings


Endoscopists can find and treat problems during the procedure. They commonly remove any polyps (abnormal growths) that they find and can test them for cancer. The removal of polyps also prevents possible cancer from developing or spreading.

During your colonoscopy, the endoscopist can:

  • Remove polyps (polypectomy)
  • Seal wounds
  • Inject medications
  • Remove blockages
  • Place stents
  • Treat tissues with laser-like therapy

Artificial Intelligence (AI) Technology

Hackensack University Medical Center is the only hospital in New Jersey, and the first in the tri-state area, to receive a grant to provide artificial intelligence (AI) assisted colonoscopy technology to low-income and underserved communities. The AI endoscopy module, authorized by the FDA in April 2021 uses computer-aided detection algorithms to identify colorectal polyps of varying shapes and sizes in real time, facilitating the diagnosis and prevention of colorectal cancer, the second leading cause of cancer-related death in the U.S. At the discretion of their doctor, any patient having a screening colonoscopy can be screened with the assistance of AI at no extra cost and the procedure is covered by all insurances. Patients with a history of polyps; younger patients and patients with a history of inflammatory bowel disease are likely to benefit most from the increased precision of the test.
