X-ray (barium enema) colon: indications, preparation, conduct


With the growth in the share of cancer and other inflammatory processes in different areas of the intestine is straight, sigmoid, of the colon – the role of imaging techniques to rule out such situations. X-ray examination is the first method that doctors prescribe for the implementation of the diagnostic search. It can be in the form of the overview snapshot or with the use of contrast compounds (barium). In addition to the graphical methods successfully used barium enema. The article presents modern data on how research is conducted, what its advantages and disadvantages.

Varieties of x-ray methods for the study of colon

First we need to clarify which departments are considered part of the colon. This loop of the ascending, descending and transverse parts of the colon, Sigma (sigmoid colon), rectum. In all of these areas are features of the structure. They are taken into account when conducting an investigation such as x-ray.

The testimony, in order to assign x-rays of this area of the gastrointestinal tract are numerous. To start, here are the conditions in which the necessary x-rays of the abdomen.

  • Pain in the right hypochondrium.
  • Pain, combined with ulcerative lesions of the gastric mucosa and duodenum (section of small intestine).
  • Suspected urolithiasis.
  • Probable intestinal obstruction.

Study without contrast is able to eliminate the critical situation specified in the list of readings.

Diagnosis by this method has the main purpose the verification, and the exclusion of certain acute pathologies.

Diagnostic methods with barium and other contrast compounds more precisely identify inflammatory or oncological diseases of small intestine and colon:

  • Crohn’s Disease.
  • Inflammatory diseases of rectum and sigmoid.
  • Ulcerative colitis and suspected him.

  • Functional obstruction.
  • Diagnosis of tumors or the dynamic monitoring of their condition.
  • Colonic ulcerative lesions of the plot.

Approximately the same range of diseases it is possible to identify or exclude when performing a double contrast: barium and air.

There are situations when irrigoscopia study is contraindicated.

  • Somatic decompensation in cardiac and renal pathology.
  • Pregnancy.
  • Unconsciousness.
  • Perforation of the mucosa with the risk of getting intestinal contents into the abdominal cavity.

These pathologies should be considered when the direction of the patient for this examination.

How to conduct research?

An important role for adequate diagnosis of intestinal pathology plays a competently trained. It includes the use of a diet that eliminates the consumption of calabrossa and carminative products: cabbage, soy, dairy products, peas. Optimization of the water regime includes drinking at least 2 liters of fluid during the day.

The day before the study morning patient Breakfast as usual, but use laxatives. The best fit Bisacodyl. During lunch, which should be lightweight, you need to take the salt laxative drug. Dinner should be skipped. Overnight Bisacodyl is used in the form of candles. On the morning of the study day can not eat anything. Also used Bisacodyl or other laxative.

Then in the x-ray Cabinet under study. To start is the overview of the abdominal organs. Then the injected contrast mixture (oral barium). A series of snapshots at five-minute intervals. The film evaluates the doctor-the radiologist.
When you double contrast study using air injection in intestinal loops. The study produces pictures where you can see the various radiological signs of pathology. Frequent of them – filling defect. This indicates the presence of ulcerative lesions or tumors of the type «plus-cloth».

To make a diagnosis, should be combined x-ray picture with clinical manifestations.

The results of the study can be obtain during the day. A doctor specializing in imaging techniques, writes its conclusion that the determination of the disease and the treatment assignment is based doctor-Clinician.

How to make an x-ray examination of the large intestine?

The direction to this study fills in and gives the doctor a wide profile. This can be a General practitioner, a surgeon. It may also issue a gastroenterologist. Therefore, in order to get to the x-ray thin, colon or rectum, it is necessary to consult these professionals. They tell in detail about where to go and whether you want this survey, what risks it involves, how to prepare for it. You need to remember that radiation exposure from this technique is the maximum it can reach 12 mSv.

The analogue method can be sigmoidoscopy. But you need to know that this endoscopic technique only penetrates the rectum and sigmoid. Pathology of the upper sections of the intestine is not visualized in this study. An alternative would be a colonoscopy – endoscopic examination of the large intestine.
