X RAY ENTEROCLYSIS Enteroclysis is an x-ray of the small intestine that looks at how a liquid called contrast moves through the area
INDICATION Mal absorption Small bowel obstruction Inflammation of the small bowel (such as Crohn's disease) Intestinal stricture Tumors of the small intestine Polyps Unexplained gastrointestinal bleeding
CONTRA INDICATION Pregnant women and children are more sensitive to the risks of x-ray radiation Allergies to contrast
EQUIPMENT AND ACCESSORIES Fluoroscopy machine. NJ tube Methyl cellulose
GOAL OF THE STUDY Both "real time" pictures and still images are taken. Patient is asked to change positions during the exam. The test usually lasts several hours, since it may take a while for the contrast to move through the entire small bowel.
Patient preparation A clear liquid diet is suggested for at least 24 hours before the test. Laxatives may be prescribed to make sure the bowel is clear of any particles that might interfere with the study. Previous investigation reports Check for allergic reaction Well informed written consent. Enquire about glaucoma and heart disease Radio opaque materials should be removed from the region of interest
PROCEDURE This examination will be performed by Radiologist (a doctor specializing diagnosis using x-rays) with the help of a radiographer or nurse. The patient will be positioned on an examination table A local anesthetic spray is sprayed into your nose and/or throat to allow for a smooth and comfortable passage of a small soft plastic tube (NJ tube) through your nose and throat into your stomach, and then into your small bowel. For single contrast microbar suspension given. For double contrast methylcellulose is given
Cont.. Barium liquid and a solution called methylcellulose (contrast medium) is then put down the tube and a series of x-rays are taken. This is watched on a television screen. You will be in a lying position at the start of the examination but during the test the x-ray machine will tilt slowly up and down. You may be asked to lie in various positions to have x-rays taken. Sometimes the barium is slow to pass into the small bowel and the procedure may take up to an hour. The placement of the tube may be uncomfortable. The contrast medium may cause a feeling of abdominal fullness.
Cont… During the examination you may be given an injection of muscle relaxant to help speed up the passage of the barium. The catheter is being held up at the pylorus. When this occurs, rolling the patient to the left will widen the bulb, allowing the catheter to advance into the duodenum. Additional x-rays may be made immediately after the procedure in order to obtain greater details of the area under examination. Often, additional x-rays are made after the barium has been excreted from the bowel, which is usually one or more days after the procedure.
complication The placement of the tube may be uncomfortable. The contrast material may cause a feeling of abdominal fullness. Rupture the loop as the tube pass through
