A guide to colonoscopy: 

Supporting early detection, prompt treatment 

A colonoscopy is an important screening method for colon polyps and colorectal cancers, which is one of the most common cancer types affecting U.S. adults. Not only is colonoscopy the gold standard for colorectal cancer screening, it can also be used to biopsy or remove tissue for further analysis. In this way, it can serve to prevent cancer by resecting pre-cancerous polyps. 

By partnering with the talented team at Triborough GI, you know all of your procedures are in excellent hands. Our practice is led by seven board-certified gastroenterologists at four New York City locations in Brooklyn, Bronx and Staten Island. This level of expertise supports utmost safety, one of a kind care, leading to optimal treatment outcomes.

A quick intro 

The colonoscopy involves using a long, thin tube or colonoscope to examine the inside of your colon or large intestine. This flexible tube has a small camera and light to see growths and other anomalies better. It is also equipped with other instruments, which may be used to remove tissue/polyps for further investigation and to perform certain minimally invasive treatments.


 Screenings for cancers of the colon and rectum (known collectively as colorectal cancers) should be done at regular intervals, starting at the age of 45, for individuals who are at “average risk.” We can also advise on the most suitable age to begin screenings if you are at higher risk of developing colorectal cancer. 

Risk factors include: 

  • Family history
  • Personal history of certain syndromes associated with the widespread development of polyps 
  • Comorbidities, such as Crohn’s disease and ulcerative colitis
  • Previous abdominal radiation therapy

Additionally, a colonoscopy may be performed to get to the source of changes or concerns, ranging from persistent belly and rectal pain to bleeding in the stool and loose stools. 

What to expect

While a colonoscopy can seem daunting, with the right preparation and planning it is a quick and manageable procedure with major health benefits.

It is essential to share your medication and supplement list with one of our specialists. Some medications need to be stopped prior to the procedure. It is also necessary to properly cleanse the colon. This involves drinking a specific bowel prep, which is prescribed prior to the procedure. It is important to follow all the instructions, as we must be able to see inside the colon clearly, and failure to properly cleanse can affect the results.

Before starting the colonoscopy, an anesthetic medication will be administered through an intravenous catheter. So you won’t feel any discomfort. After the colonoscope is inserted the entire large intestine (colon) will be examined. We carefully inspect the walls of the colon for any irregularities and precancerous changes. Photos are taken for documentation. After any abnormalities are biopsied or resected, the scope is then withdrawn, and you will relax in our recovery room until the medication wears off. The results from the colonoscopy will be reviewed promptly with you, and we will discuss further steps, such as other testing or follow-up appointments. We will also advise when to return to your “routine” and what to eat or drink following the procedure. A colonoscopy is nothing to fear. It can be a lifesaver and a vital preventative measure that supports early detection and treatment. Call (718) 332-0600 to speak with one of our skilled professionals in Brooklyn, NY, today.
