Preparation of patients for examination of the gastrointestinal tract with contrast agents:

 Irrigoscopy (X-ray examination of the colon)


Cleansing the colon from feces, fluids and mucus is the main task of preparing for the procedure, the solution of which ensures the success of the examination.

On the day of the examination:

         In the morning, put 2 cleansing enemas with a volume of 1.5 liters each. To put a cleansing enema with cool or cold water is not recommended because of stimulation of gas formation in the intestine. After the last enema, the wash water should not contain impurities of stool, otherwise the procedure is repeated until the indicated effect. Controlling the nature of the stool by the patient himself is an extremely important preparation moment!
