Top Doctors: Understanding colonoscopy

Routine colonoscopy, which provides an internal image of the rectum and colon, is widely considered the best way to prevent colon cancer. Yet health experts say that too few middle-age Americans get screened because they don't know they need to be tested or they find it inconvenient, embarrassing or unnecessary.

Prepping for a colonoscopy - more than the procedure itself - is what many people dread. The day before a colonoscopy, the person must go on a clear-liquid diet. Also, the bowels must be cleared. This means drinking special solutions, taking laxative-type pills or some combination.

"A lot of people want to bury their heads in the sand," noted Dr. Alfredo Kalafatic, a colon and rectal surgeon in Bethpage. "They don't want to hear bad news, and they don't want to put up with the prep, especially male patients."

Most colonoscopies are performed under sedation, to keep the person relaxed. The physician uses a colonoscope, which is a lighted, flexible tube equipped with a tiny video camera. It is inserted into the anus and guided though the rectum and into the colon to look for abnormal growths, called polyps. If anything looks suspicious, a biopsy can be done, removing a small piece of tissue for testing, or whole polyps can be removed. Instruments needed for this can be passed through the colonoscope.


Colorectal cancers often begin as polyps. Removing them can prevent this typically slow-growing cancer from ever developing.

"In 30 years of doing colorectal cancer surgery, it was the exception to the rule that I operated on any patient who had colon or rectal cancer who had had a colonoscopy," said Dr. Michael D. Moseson, a Great Neck colon and rectal surgeon who serves as chief of the division of colon and rectal surgery at ProHEALTH Care Associates in Lake Success.

Though the death rate has declined over the past two decades, colorectal cancer remains the third most common cancer in men and women. The American Cancer Society estimates that 142,570 new cases of colon and rectal cancer will develop this year, and 51,370 people will die.


Colonoscopy is generally considered a safe procedure, but there is a small risk of complications, according to the American Gastroenterological Association. The scope can puncture the wall of the colon or rectum, for instance, sometimes requiring surgical repair. Removing polyps also can cause bleeding, and controlling the bleeding sometimes requires blood transfusion or reinsertion of the scope.


Colonoscopy is considered the gold standard for colorectal cancer detection, but it is not the only method around.

So-called virtual colonoscopy, a popular alternative used to detect polyps, captures images using computed tomography (CT) or magnetic resonance imaging (MRI).

The problem with virtual colonoscopy, Kalafatic and Moseson agreed, is that, if a polyp is discovered or something questionable turns up on the scan, the person will end up having a colonoscopy anyway.

The Cancer Society's recommendations for colorectal cancer screening vary, depending on how at risk people are for the disease. Risk factors for colorectal cancer include:

  • Being older than 50.
  • Having had precancerous polyps or colorectal cancer.
  • Having inflammatory bowel disease, including Crohn's disease and ulcerative colitis.
  • Having a strong family history of colorectal cancer or polyps.
  • Having a family history of an inherited type of colon cancer.
  • People with no identified risk factors, other than age, should begin regular screening at age 50 and have the testing repeated every 10 years, the Cancer Society recommends.


    From 2005 to 2009, Stony Brook University Medical Center and the Suffolk County Department of Health Services participated in a federally funded demonstration project designed to boost colon cancer screening rates among the region's uninsured and underinsured.

    To increase people's compliance with the colonoscopy protocol, a lead clinician conducted the initial visit by phone, taking a detailed medical history, scheduling the colonoscopy and providing detailed instructions. That phone call eliminated the need for the person to make two visits to obtain a colonoscopy.

    Based on the success of "Project SCOPE" (the Suffolk County Preventive Endoscopy Project), Stony Brook's gastroenterology service now routinely places precolonoscopy telephone calls to people before their procedures.
