Direct Access Colonoscopy

Penn Medicine Princeton Medical Center’s (PMC) Center for Digestive Health is pleased to offer a convenient and innovative program, Direct Access Colonoscopy, to help speed the scheduling routine screening colonoscopies. You can schedule a procedure without first having an office visit with a gastroenterologist if you meet these criteria:

  • Must be aged 50 or over
  • If you have a family history of colon cancer, are 40 or older and have not been screened
  • If you have no significant heart, lung, liver or kidney disease (ask our nurse for details)
  • If you are not on blood-thinning medications other than routine aspirin use (ask our nurse for details)
  • Must not have a history of stroke or blood clots
  • Must not have active asthma

Individuals who meet the criteria above can call 609.853.6390, option 2 to make an appointment for a colonoscopy.

Individuals who do not meet these criteria, or those who have specific gastrointestinal complaints, should discuss colonoscopy with their primary care physicians or schedule an appointment to see one of our gastroenterologists prior to scheduling a colonoscopy.


Facilities where colonoscopies are provided include:

  • Penn Medicine Princeton Medical Center

Prep Instructions

Once individuals schedule a procedure through the Direct Access Colonoscopy program, a nurse will give them instructions on how to prepare. Prep instructions can vary by individual, but generally patients prepare the day before the procedure by fasting and taking laxatives to clear their digestive system. Patients can consume clear liquids, but will stop liquids prior to their procedure as instructed. Other instructions, such as stopping medications, may also be provided.

The Day of the Procedure

On the day of the procedure, the patient will arrive at the outpatient facility with a designated driver, as the patient will be unable to drive home after being sedated. One of the participating gastroenterologists will perform the colonoscopy, which involves passing an endoscope through the patient's rectum to find and remove suspicious tissue or growths for further testing. The physician will discuss any findings and instructions with regard to any follow-up care needed with the patient once he or she wakes up. Patients return home the same day and are able to return to work and normal activities the following day.

An Exceptional Team

The Direct Access Colonoscopy team consists of board certified gastroenterologists, anesthesiologists and specially trained nurses. The staff who perform colonoscopies are always focused on your health, safety and comfort.

Colonoscopy – the gold standard in detection

A colonoscopy screening after age 50 is highly advisable, even if you are healthy and have no symptoms or risk factors. By identifying and removing precancerous polyps, this exam can help to detect and prevent cancer.

The Direct Access Colonoscopy Program makes planning this recommended procedure quick and easy.
