Barium enema examination/Examen de enema de bario.

A barium enema is an x-ray examination of your large intestine or colon. This procedure is performed when patients have a change in bowel habits, experience abdominal pain or rectal bleeding or if your doctor suspects you have diverticuli (small pockets in the lining of your intestine where food can get trapped) or polyps (small growths) in your colon.

Patient Preparation

For the examination to be successful, your colon must be completely empty. You will be asked to follow a special diet the day before the exam and take a laxative to help clear your digestive tract. You probably will be asked not to eat or drink anything after midnight the night before the exam. Your doctor or the radiology department will give you specific instructions, which you should follow closely. If you are diabetic or take medication dally, notify the person who gives you the instructions and schedules your exam.

Before your exam, a radiographer will explain the procedure to you and answer any questions you might have. The radiographer, also known as a radiologic technologist, is a skilled medical professional who has specialized education in the areas of radiation protection, patient care and radiographic positioning and procedures.

You will be asked to remove your clothing and wear a hospital gown. If you are a woman of childbearing age, the radiographer will ask if there is any possibility you are pregnant. It is important that you tell the radiographer the date of your last menstrual period and whether there is a chance that you may be pregnant.

During the Examination

Inside the x-ray room, you will be asked to lie down on a tilting table attached to a fluoroscope, which is an x-ray unit combined with a television screen. The radiographer will take an x-ray image, also known as a radiograph, of your abdomen to make sure that your colon is clean. Next, the radiographer will insert a lubricated enema tube into your rectum.

A radiologist, a physician who specializes in the diagnostic interpretation of medical images, will come into the room and begin the examination. Liquid barium will flow through the enema tip, a little at at a time. Barium is a special compound that coats the walls of your colon and makes it show up more clearly on x-ray film. While the barium is being delivered, the radiologist watches images of your intestine on the fluoroscope. You may be asked to hold your breath, change your position or remain still. If you feel uncomfortable or are not able to turn over, you should tell the radiographer or radiologist. Their goal is to make you as comfortable as possible and at the same time perform a successful examination.

In some cases, the radiologist may pump air along with the barium solution into your intestine through the enema tip. You may feel bloated or experience cramping. It is important that you try not to expel the air or the barium. This examination commonly is called an air contrast barium enema examination. The air is used to expand the walls of the colon, allowing a more detailed image.

After the radiologist has taken the necessary images, the radiographer will take a series of images of your large intestine. Once the films are complete, you will be allowed to go to the bathroom to expel the barium. After you have expelled the barium, the radiographer may take another x-ray image to determine whether any barium remains.

Next, the radiographer will process your x-ray films and determine whether they are technically acceptable. The films then are interpreted by the radiologist.

Postexamination Information

After your radiographs have been reviewed, your personal physician will receive a report of the findings. Your physician then will talk to you about the results and discuss what further procedures, if any, are needed.

Increase your water intake in the days following your examination. The barium may make your stools white for a few days. This is normal. If you are constipated following the exam, tell your doctor. You may be advised to increase your water consumption or take a laxative.

La enema de bario es un examen de rayos X de su intestino grueso o colon. Se realiza dicho procedimiento cuando los pacientes sufren cambios en sus habitos intestinales, tienen dolor abdominal o sangrado rectal, o si su medico sospecha que pueda tener diverticulos (pequenas bolsas en el revestimiento del intestino donde los alimentados pueden quedar atrapados) o polipos (pequenos bultos) en el colon.

Preparacion del Paciente

Para que el examen tenga exito, su colon debe estar completamente vacio. Se le pedira que haga una dieta especial el dia antes del examen y que tome un laxante para limpiar su tubo digestivo. Probablemente, se le pedira que no coma ni tome nada despues de la medianoche anterior al examen. Su medico o el departamento de radiologia le dara instrucciones especificas, las que debera seguir al pie de la letra. Si usted es diabetico o toma medicamentos a diario, notifiqueselo a la persona que le de las instrucciones y marque su examen.

Antes de su examen, un tecnologo radiologo le explicara el procedimiento y respondera a sus preguntas. El tecnologo radiologo, tambien conocido como tecnologo en radiologia, es un profesional medico especializado con estudios en las areas de proteccion contra la radiacion, atencion de pacientes y posicionamiento y procedimiento radiologicos.

Se le pedira que se desvista y vista una bata de hospital. Si usted es una mujer en edad de tener hijos, el radiologo le preguntara si es posible que este embarazada. Es importante que le informe al tecnologo radiologo la fecha de su ultimo periodo menstrual y si es posible que este embarazada.

Durante el Examen

En la sala de rayos X se le pedira que se acueste sobre una camilla reclinable sujeta a un fluoroscopio, que es una unidad de rayos X combinada con una pantalla de television. El tecnologo radiologo tomara una radiografia de su abdomen para asegurar que su colon se encuentre limpio. A continuacion, el tecnologo radiologo le insefira un tubo de enema lubricado en su recto.

Un radiologo, medico especializado en la interpretacion diagnostica de imagenes clinicas, entrara a la sala e iniciara el examen. Poco a poco, pasara bario liquido a traves de la punta de la enema. El bario es un compuesto especial que reviste las paredes de su colon y hace que se vea mas claramente en la placa de rayos X. Mientras fluye el bario, el radiologo observa las imagenes de su intestino en el fluoroscopio. Se le podra pedir que no respire, cambie de posicion o permanezca inmovil. Si se siente incomodo (a) o no logra darse vuelta, debe decirselo al tecnologo en radiologia o al radiologo. El objetivo de ellos es lograr que usted se sienta lo mas comodo(a) posible y, al mismo tiempo, realizar un examen exitoso.

En algunos casos, el radiologo podra bombear aire dentro de su intestino, junto con la solucion de bario, a traves de la punta de la enema. Podra sentirse hinchado (a) o sentir dolor. Es importante que no intente soltar el aire o el bario. A este examen se lo llama comunmente examen de enema de bario con contraste de aire. El objetivo del aire es expandir las paredes del colon para permitir una imagen mas detallada.

Una vez que el radiologo haya tomado las imagenes necesarias, el tecnologo en radiologia tomara una serie de radiografias de su intestino grueso. Una vez tomadas las radiografias, se le permitira ir al bano y expulsar el bario. Una vez que haya expulsado el bario, el tecnologo radiologo tal vez le haga otra radiografia para determinar si quedaron restos de bario.

Luego el tecnologo en radiologia procesara sus placas de rayos X para determinar si son tecnicamente aceptables. A continuacion, el radiologo interpretara las placas.

Informacion de Pos-examen

Una vez analizadas sus radiografias, su medico personal recibira un informe de los resultados. Su medico luego conversara con usted sobre los resultados y discutira que procedimientos futuros, si los hubiera, serian necesarios.

Aumente la cantidad de agua que toma en los dias siguientes a su examen. Su materia fecal podra ser blanca durante algunos dias debido al bario. Esto es normal. Si tiene constipacion despues del examen, informeselo a su medico. Podra recibir instrucciones de aumentar su consumo de agua o tomar un laxante.
