Endoscopic Ultrasound

Endoscopic ultrasound is a tool to detect cancerous growths and abnormalities in the digestive system. It has two procedures. One is used to check the esophagus ( food tube ) for growths and obstructions. The transducer is a small flexible tube that is inserted in the patients throat. A camera on the tip transmits a picture on the computer screen so the doctor can examine it down to the stomach.For more on the transducer and how ultrasound works, click here

An exam of the colon is one that is inserted into the small intestine ( duodenum ) through the anal canal. It is similar to the esophagus exam. It detects cancer, pancreatitis, abnormalities in the gallbladder and liver. It is also to study nodules on the intestinal wall, and study the sphincter muscle to determine the reason for fecal incontinence.

Preparing for the exam. Also see exam prep for various ultrasounds.

You will be asked to fast and take a laxative to clear out your intestines. You will be asked to drink only clear liquids such as water, apple juice, ginger ale, sprite, beef or chicken broth with no noodles, black coffee or tea without milk or cream. You can also have milk, most sodas, sherbet, popsicles and jello. Avoid anything with red or orange color.

You should not be taking aspirin or anti-inflammatory drugs (Motrin, advil, etc). There is a a chance is bleeding if the doctor removes a polyp or biopsy. If you take insulin, consult with your doctor about changing regimen.

You will be sedated and will need to have a ride home later because you will not be able to operate machinery of any kind. Many lives have been saved by early detection using endoscopic ultrasound. Back to types of ultrasound
