EUS refers to endoscopic ultrasound, this is the comprehensive evaluation of the walls of your upper and lower gastrointestinal tract. The upper tract contains the esophagus, stomach, and duodenum; the lower tract includes your colon and rectum. EUS examines the internal organs adjacent to the gastrointestinal tract, these include the gall bladder and pancreas.
A tube known as an endoscope will be used for the procedure. This is passed through the mouth or anus. Ultrasound equipment will be activated to render visual restorations of the digestive area.
An EUS is done to provide a better picture of the digestive tract anatomy. EUS can also be used to diagnose the causes of abdominal pain or abnormal weight loss. Abnormalities such as growths can also be detected at a previous endoscopy procedure or x-ray. The growth is examined in detail and used by the doctor to determine the best method for treatment.
Patients with cancer are frequent candidates for EUS. They examine the extent of cancers affecting the digestive and respiratory systems. An accurate assessment of the cancer’s depth and progress can be made. This assists in the determination of the proper treatment.
You can prepare for EUS by avoiding any foods for at least six hours before the exam. Inform the doctor about any medications you are taking or allergies you may have. You will be provided with instructions on what medications are safe to take. Aspirin and nonsteroidal anti-inflammatories are generally acceptable before an EUS examination.
Possible complications of EUS include bleeding at the biopsy site, this is generally minimal and will quickly dissipate. A sore throat may also be experienced for one or two days. On the same day after the treatment, you may be free to eat a light meal. The results of the procedure may be provided on the day of the exam as well, although some tests may require a longer wait.
