Before the Procedure
You should drink only clear liquids after midnight the night before the exam and have nothing by mouth four hours prior to the procedure.
You should always check with your physician about taking any medication the day of your exam. This includes over-the-counter medications and herbal supplements. You may be advised to stop taking any blood thinners (such as aspirin, vitamin E, ibuprofen or Coumadin) two weeks prior to the exam, or modify the dose (insulin, oral hypoglycemic, blood pressure and cardiac medications) the day of the exam. Please bring a list of ALL medications you take with you.
During the Procedure
The procedure for an EUS is similar to that of an upper endoscopy: after registering, you will be brought to a private exam room where a specially trained nurse and your physician will review your medical history, explain the procedure and answer your questions prior to the procedure. In the Preparation Room, an IV site will be established and your vital signs will be monitored closely.
You will be placed on your left side, and after sedation is achieved, the physician will pass the scope through your mouth along your esophagus into your stomach while watching a TV monitor. Air and water is used to slightly inflate the stomach and wash away any residual food so that the lining of the stomach and small intestines can be seen clearly. If an abnormality such as a mass or abnormal appearing lymph nodes is seen, a sample of tissue (needle biopsy) may be taken during this procedure. The tissue sample will be sent to the pathology lab for evaluation. Results are usually available within a week. The actual procedure may take 30 - 60 minutes, longer than an upper endoscopy.
The EUS is usually well tolerated and rarely causes discomfort. After the procedure, you will be brought to a recovery room where your vital signs are monitored for a brief period. You will be discharged with a family member or a friend. You should allow 2- 3 hours for the total visit.
After the Procedure
Discharge instructions will be reviewed with you prior to the start of the exam and will be given to you on discharge from the unit. The doctor will speak with you and a family member (if you wish) after completion of the procedure. The results of your exam and any other instructions will be written upon completion of your procedure.
You must be discharged with a person who will drive you home and assure your well being after arriving home. Please arrange to have someone stay with you or be accessible if a problem arises after discharge. This is especially important for elderly patients and those with significant medical histories, such as diabetes and cardiac conditions.
You will be instructed not to drive or drink alcohol for the rest of the day. Patients are advised not to do any activities that require mental acuity or physical activity, such as sports, legal decisions, or using power tools. You should rest at home with light activity for the remainder of the day.
In most cases, patients may resume their usual diet immediately. If your doctor advises differently, this will be noted on the instructions.
A small percentage of patients experience a mild sore throat after the procedure and this usually resolves in a day or so. If persistent discomfort persists, you should contact your doctor.
You may resume your usual medications unless indicated on the discharge instructions. If biopsies were done, your doctor may advise holding blood thinners, such as aspirin, Ibuprofen and Coumadin for several days to prevent bleeding.
