GI Lab - Gastrointestinal Endoscopy

Drawing of intestinal tract

Welcome to the Rocky Mountain Regional VA GI Lab! Our doctors, nurses and technicians are committed to providing high quality, state-of-the-art gastrointestinal endoscopy services for our Veterans, and we offer several resources here to help you understand and prepare for your upcoming procedure. If you have questions after reading about your procedure here, please don't hesitate to call us at the phone number above.

COVID-19: Currently, all patients are required to have a COVID-19 screening test 48 to 72 hours prior to their scheduled procedure. COVID-19 testing is offered at the Rocky Mountain Regional VA Emergency Department and at the PFC Floyd K. Lindstrom VA Clinic in Colorado Springs. If you do not have a COVID test prior, your procedure will be canceled.

How to find the GI Lab for Your Procedure

We are in the Rocky Mountain Regional VA Medical Center in Aurora, Colorado. After entering the building, take elevator 1 to the third floor. (Elevator 1 is located near the South entrance on N. Wheeling St.) Check in at the Mt. Harvard waiting area, third floor of Building D, Diagnostic & Treatment South.

Procedures We Do, and How to Prepare for Them

If you do not see your specific procedure on this list, or if you are having several procedures at one time, please call us at the number listed at the top of this page.

Sometimes, our doctors “customize” procedure preparation for a patient. If your doctor does so, you will receive in the mail specific instructions or we will call you to discuss them. Please call us with any questions or concerns.

General Information for the Day of Your Procedure

Most of our procedures require that you not have anything to eat or drink after midnight on the day of the procedure, for your own safety. Please see your instructions for specific information.

We usually make an exception to the “no eating or drinking after midnight” rule for prescription medications. Most medications may be taken but you must do so at least FOUR HOURS BEFORE your procedure, with a few sips of water to swallow any pills, tablets or capsules. Please see your instructions for specific information as certain procedures require you stop certain types of medications.

Most blood thinning medications (anticoagulants such as warfarin or apixaban and antiplatelets such as clopidogrel or 325 mg sized aspirin) must be stopped several days prior to your procedure. If you have a provider or team that manages your blood thinning medications, such as a cardiologist, primary care provider, or an Anticoagulant Clinic, please reach out to them for specific information.

If you are managed by the Eastern Colorado Health Care System VA Anticoagulant Clinic and are taking any of the following medications, please call (720) 723-6756 or (719) 227-4131:

  • Warfarin (Coumadin®)
  • Apixaban (Eliquis®)
  • Dabigatran (Pradaxa®)
  • Edoxaban (Savaysa®)
  • Rivaroxaban (Xarelto®)
  • Dalteparin (Fragmin®)
  • Enoxaparin (Lovenox®)
  • Fondaparinux (Arixtra®)

Usually, the doses of diabetes medications must change during preparation for a colonoscopy. Diabetes medications are generally not taken the day of any procedure. Please see your instructions for specific information.

Check-in for your appointment 60 minutes beforehand.

Being Sedated

Most (though not all) of our procedures are done with intravenous sedative medications. There are different types of sedation that might be used:

  • Moderate – You will feel very drowsy and may fall asleep during the procedure. You may or may not remember parts of the procedure.
  • Deep – You won’t be unconscious, but you’ll sleep through the procedure and will probably have little or no memory of it.

A few of our procedures are done under general anesthesia, depending upon the procedure and your overall health.

No matter the type of sedation, you are not permitted to leave by yourself after a sedated procedure. Driving after you’ve had sedatives is like driving under the influence of alcohol. If you are being sedated, you must have a responsible adult companion with you on the day of your procedure to take you home or it will be cancelled.

If you are having an unsedated procedure, you may come alone for it. The staff member who schedules you will tell you whether your procedure requires sedation. Please call us with any questions or concerns you might have about sedation.

Because of current COVID-19 precautions, your driver will not be allowed inside the facility and must have a phone so that we can call them when you're ready to leave.

FAQs

Note: Click on the question to see the answer.

You can get instructions from this website! Just click on the “Getting ready” link for your procedure above. We can also mail them again but need about a week to do so.

If you use secure messaging in MyHealtheVet, call us at 720-723-6166 and leave a voice mail asking us to send the instructions that way.

The instructions are also recorded and available for you to listen to on the phone, at 720-723-6166. (Please listen to the automated menu options to be connected to the right recording.)

You will need a driver if you are to be sedated. We may have resources available to assist you with a ride but generally need two weeks to arrange for these. You will need to call and reschedule if a driver cannot be found.

Currently, due to COVID-19 safety measures, no companions are allowed with you inside the hospital for an appointment. You will still need that driver though. They must have phone access so we can call them after your procedure; they can pick you up at our south entrance once you are discharged.

This depends on your procedure and the type of sedation you are to receive. Our goal is to keep you comfortable and still breathing! Under moderate sedation, most patients fall asleep and then wake up towards the end of the procedure. Please see “Being Sedated” for more information.

We request that you show up and check in one hour before your procedure time.

We ask that you refer to the instructions for your specific prep medication, but most require you take one dose the night before your colonoscopy, and a second dose early in the morning on the day of your colonoscopy (“split dose”).

This depends on your procedure and your prep. Please refer to the specific instructions.

This depends on the medications. Routine medications such as blood pressure pills and heart medicines should be taken. Blood thinning and diabetes medications should not be taken unless you’ve been told otherwise by a health care provider. Please refer to your instructions.

The procedure time varies depending on the procedure, your anatomy, health history, and what the doctor finds. We need time to get you ready for the procedure, and for you to wake up afterwards if you’ve been sedated. Most colonoscopies take anywhere from 15-45 minutes, and most upper endoscopies take between 5-15 minutes. Of course, there are many factors that could cause a procedure to take longer. It is best to prepare to be at the hospital for 3-4 hours.

We make every effort to be on time for you! However, it’s difficult to know exactly how long any procedure will take, and our providers are very thorough and careful with each Veteran to make sure all their needs are taken care of. We ask for your patience if we do run late and cannot start your procedure exactly on time.
