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 for certain patients who are ages 50 and over.

Individuals can call 609.750.3040, option 3 to make an appointment for a colonoscopy and if they meet certain screening criteria, they will be scheduled to have a colonoscopy performed by a board certified gastroenterologist.


To be eligible to schedule through the Direct Access Colonoscopy program, individuals must 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
  • Cannot have a history of chronic obstructive pulmonary disease
  • Must never have been diagnosed with congestive heart failure
  • Must not have experienced chest pains or a heart attack within the past 12 months
  • Cannot be on blood-thinning medication other than routine aspirin use or have a history of bleeding disorders (ask our nurse for details)
  • Must not have a history of stroke or blood clots
  • Must not have active asthma

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, Stephen & Roxanne Distler Center for Ambulatory Surgery, 5 Plainsboro Road, Suite 200, Plainsboro, NJ 08536
  • Center for Ambulatory Surgery — Monroe, 8 Centre Drive, Monroe, NJ 08831

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.
