We look forward to your visit with us. Please take a few moments to read the following instructions:

    On the form titled “Patient Questionnaire” do not forget to list the name, address, telephone and fax number(s) of your referring physician and primary care physician who need a copy of the procedure report. HAND CARRY ALL COMPLETED FORMS WITH YOU TO YOUR APPOINTMENT.  Please fill out all forms accurately and completely. These will assist us in your care and expedite your waiting time with us.


  • Please check-in at Ambulatory Care Unit (ACU) located on the 3rd Floor of 1101 Van Ness, San Francisco, CA 94109.


  • VERY IMPORTANT: PLEASE PRE-REGISTER WITH CPMC. If you have not received a call from the CPMC Pre-Registration Department (Patient Access Center) one week prior to your appointment, please contact them at 855-398-1637 (toll-free) Monday – Friday from 8:00 am – 5:00 pm. Please tell them you have a procedure scheduled in Interventional Endoscopy. Registration is a two-step process. You will speak to a registrar who will take your insurance and demographic information. You will then speak with a registered nurse who will take your health history. Please have your medication list and insurance card available for this interview.


  • HAND CARRY YOUR X-RAY FILMS TO YOUR APPOINTMENT. If you have ultrasounds, MRI’s, CT, PET or HIDA scans and/or MRCPs in relation to your procedure in Interventional Endoscopy, please HAND CARRY these images on a CD to your appointment. If these images were done at CPMC, you do not need to bring them with you. We can view them internally. If you bring in images on a CD, the physician may keep them with your records.


  • PREOPERATIVE TESTING SUCH AS A HISTORY AND PHYSICAL, LAB WORK (within two weeks of the procedure) and/or EKG may be necessary prior to the procedure to ensure your safety during anesthesia. Please have your doctor’s office fax these items to 415-375-4861.


  • If you are on Coumadin, aspirin, or other anti-inflammatory drugs (i.e., Advil, Ecotrin, Motrin, Naprosyn, Celebrex, etc) please notify your prescribing physician that we are requesting you stop these medications five days prior to your procedure. If your prescribing physician requests that you remain on your blood thinner or anti-inflammatory medication, CONTACT OUR OFFICE IMMEDIATELY.


  • If you are on Plavix, please notify your prescribing physician that we are requesting you stop this medication 7 days prior to your procedure. If your physician requests that you remain on this medicine, PLEASE CONTACT OUR OFFICE IMMEDIATELY.


  • If you are diabetic, please inform the pre-registration nurse. Check your finger stick glucose before leaving home and notify the nurse of the result upon arrival in the Ambulatory Care Unit.




    If you have had ANY of the following: CT scans, PET scans, Xrays, Ultrasounds, Nuclear Medicine Tests, Barium Swallows, Esophagrams, MRIs, MRCPs IN RELATION to what you will be seeing our IES physicians for then YOU MUST OBTAIN THE IMAGES ON A DISC AND HAND CARRY to your appointment with us!

If you have had a Colonoscopy and/or Endoscopy (including Capsule Endoscopy) IN RELATION to what you will be seeing our IES physicians for then YOU MUST OBTAIN THE PRINTED REPORT WITH COLOR PICTURES from the procedure and HAND CARRY to your appointment with us!


Please make every effort to bring these items. Your care and procedure could be altered or even canceled in the absence of images and/or endoscopy reports and pictures.


Because of the high demand for interventional endoscopy services, your physician will go to help another patient while you are still in recovery.  For this reason, they may not be able to speak with you after your procedure is completed. A complete report will be sent to your referring doctor and you may follow up with him or her for results.

If once you have recovered, you would like to speak with the physician who performed your procedure, you will be escorted to the ambulatory surgery unit waiting area after you have met discharge criteria and are dressed. We will advise the physician of your request. Because of the very busy schedule and the length of time interventional endoscopy procedures take, it may be one or two hours before the physician has completed a case and is able to speak with you.


We wish to provide excellent patient care and meet the needs of both our patients and their families. Occasionally unexpected durations of prior procedures and emergent procedures may cause a delay in your scheduled appointment. We will do our best to minimize any delays. We ask for your understanding so that every patient receives dedicated care.
