A colonoscopy is a safe medical procedure, in which one of our Triborough GI gastroenterologists will visually examine your colon and rectum. This procedure is most commonly performed to test for colon cancer

A colonoscopy is performed by inserting a thin flexible tube (colonoscope) into the rectum, and guiding it through the colon. The colonoscope is fitted with a video camera and provides the doctor with an up-close look of the entire colon. If necessary, the colonoscope can be used to take biopsies (tissue samples). The procedure generally takes between 20 minutes to 1 hour.

Our Staten Island, Bronx, or Brooklyn based Colonoscopy doctors can schedule and perform your procedure at one of our Triborough GI clinics. 

One of our board-certified GI doctors will guide you through the Colonoscopy procedure and provide you with all the information you need prior to having the procedure. 

For more information on Colonoscopy or to schedule an appointment at our Bronx, Brooklyn or Staten Island office, please call (718) 332-0600 today.


A colonoscopy may be recommended by your physician to:

  • Screen for colon cancer or polyps (growths of tissue in the colon) 
  • Diagnose symptoms such as: rectal bleeding, abdominal pain, persistent diarrhea or constipation, etc.

Moreover, by visualizing the colon, your doctor will be able to see signs of other medical issues.


For your colonoscopy to be successful, your colon will need to be completely cleaned out. An unclean colon will make it difficult for the doctor to get clear images and may cause some abnormalities to be missed.

To make sure your colon is completely cleaned out; you may be asked to:

  • Take laxatives – Taking a laxative in either liquid or pill form, is a common recommendation and swill most likely need to be done the night before and the morning of the procedure.
  • Keep to a specific diet – You will not be able to eat solid food the day before your colonoscopy. All consumed liquids will need to be clear (water, tea, etc.). After midnight on the night before the procedure you will not be able to eat or drink anything.
  • Adjust your medications – Some medications may interfere with your colonoscopy results. Please speak with your doctor about any medication you may be taking. Your dosage may need to be temporarily adjusted.
  • Use an enema – Using an over the counter enema kit right before the procedure will effectively empty your lower colon. An enema is not a commonly recommended tool but may be helpful.

Transportation – Patients are usually given a sedative during a colonoscopy. You will need assistance after the procedure, and it is recommended to have someone take you home after your test.


In a typical colonoscopy procedure, your doctor will give you a sedative to help you relax. You won’t feel a lot of pain, but experiencing cramping, pressure, and bloating is not uncommon. The sedative will help you with any discomfort.

You will be asked to lie on your side or on your back while the doctor slowly inserts the thin flexible tube (colonoscope) into your rectum and moves it along your large intestine. Video from the device will display on a monitor, while your doctor controls the colonoscope’s movements.

You may experience an urge to use the bathroom. It is also normal to pass gas during this procedure. Make sure to let your doctor know if you are feeling any discomfort.


After your procedure you will be monitored by our office staff until the sedatives start wearing off. You may feel bloated or experience minor cramping. This is due to air that will have entered your colon during the procedure; these effects will pass quickly. After the procedure you will be allowed to eat. You may continue feeling bloated for several hours after the procedure. Flatulence may continue as well.

Your doctor will have to wait for any biopsy results to let you know if they found anything noteworthy. As previously stated, due to the sedative, you must have someone drive you home before you can be released.


While risks of a colonoscopy are rare, they are possible. The most severe of these is the perforation of your colon lining which would likely require a surgical repair.

Less severe complications can include:

  • Minor bleeding
  • Fever
  • Abdominal pain

You should immediately contact your doctor if you notice any of these complications.
