This information will help you prepare for your upper endoscopy at Memorial Sloan Kettering (MSK). The doctor will use a flexible tube called an endoscope to see the inside of your esophagus (food pipe), stomach, and first part of your small intestine on a video monitor. The doctor can remove a small sample of tissue (biopsy) and take photos during your procedure.
A Week Before Your Procedure
You may need to stop taking some of your medication before your procedure. We have included some common examples below.
- If you take medication to thin your blood, such as to treat blood clots or to prevent a heart attack or stroke, ask the doctor who prescribes it for you when to stop taking it. Some examples are aspirin, warfarin (Coumadin®), dalteparin (Fragmin®), heparin, tinzaparin (Innohep®), enoxaparin (Lovenox®), clopidogrel (Plavix®), and cilostazol (Pletal®).
- If you take insulin or other medications for diabetes, you may need to change the dose. Ask the doctor who prescribes your diabetes medication what you should do the day before and the morning of your procedure. If you take metformin or a medication that contains metformin, do not take it the day before or the day of your procedure.
- If you have an automatic implantable cardioverter-defibrillator (AICD), you need to get a clearance letter from your cardiologist (heart doctor) before your procedure.
- If you’ve had chest pain, trouble breathing that is new or worse, or have fainted in the last 6 weeks, you will need to get a clearance letter from your doctor before your procedure.
- Your MSK doctor’s office must receive your clearance letter at least 1 day before your procedure.

After changing into a hospital gown, you will meet your nurse. He or she will place an intravenous (IV) catheter into a vein, usually in your hand or arm. At first you will receive fluids through the IV, but it will be used later to give you anesthesia (medication to make you sleepy). Your doctor will explain the procedure, and answer any questions you have.
When it’s time for your procedure, you will be brought into the procedure room and helped onto an exam table. You will be attached to equipment to monitor your heart, breathing, and blood pressure. You will also receive oxygen through your nose. A mouth guard will be placed over your teeth to protect them.
You will receive anesthesia through your IV, which will make you fall asleep. Once you are asleep, your doctor will pass the endoscope through your mouth, down your esophagus, into your stomach, and into your small intestine. Your doctor will take biopsies if necessary, then remove the endoscope.Back to top
