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

ANATOMY

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
