How to prepare for a colonoscopy examination?
In order to examine the intestinal mucosa, it is necessary that there is no feces in the lumen and on the walls of the intestine. The success and information content of the study is determined mainly by the quality of preparation for the procedure, so be careful about following the recommendations for preliminary preparation and following the method of using the drug.
Preliminary preparation of the intestine for examination
If you do not suffer from constipation, you should follow the following diet for two days before your colonoscopy.
Exclude from the diet:
- all fresh vegetables and fruits, including beets (borscht), potatoes, herbs, berries
- “coloring” drinks: tomato, pomegranate juice, black coffee, Coca-Cola, etc.
- black bread, mushrooms, beans, peas
- Activated carbon
Allowed for food:
- bouillon
- semolina
- egg
- omelette
- boiled meat
- fish
- cheese
- oil
- fermented milk products, except hard cottage cheese
If you have a tendency to constipation (lack of independent bowel movements for 3 days), then you need to take your usual laxatives 2 days before the test, and also adhere to the diet described above.
While taking the drug, only liquid food (broth, sweet green tea) is consumed.
On the morning of the test, you should drink green sweet tea.
Method of use of Lavacol and dose
Dilute the contents of 1 sachet of the drug in 1 glass of water (200 ml) at room temperature. You can add syrup or jam to the resulting solution (to adjust the taste).

Lavacol and colonoscopy. Including economic aspects
High-quality preparation of the colon is the most important factor determining the effectiveness of colonoscopy, its duration and the success of therapeutic procedures, reduces the risk of complications, eliminates the need for repeated examinations, which also affects the economic side.
The condition for ideal preparation of the colon for colonoscopy is the complete absence of contents in the intestine or a moderate amount of residual clear liquid, sometimes mixed with mucus, which does not interfere with a full examination and is freely aspirated. However, in daily clinical practice, endoscopists regularly encounter poor visualization during colonoscopy. Preparing the colon for colonoscopy is a complex process that usually disrupts the patient’s usual rhythm of life. The method of oral intestinal lavage using the drug Lavacol is the method of choice for the combination of safety, effectiveness and comfort for the patient when preparing the colon for examination and surgery. Taking the solution does not lead to disruption of the physiological constants of the body, hemodynamic parameters, and does not change the well-being of patients. Lavacol does not contain flavorings or additives, which makes it easier to take and improves compliance. Experience with the use of the drug Lavacol gives grounds to recommend it for widespread use in clinical practice. It is important that the use of the drug Lavacol is more economically justified for patients: Lavacol costs 170 rubles in pharmacies, Fortrans - 550 rubles. (both drugs are included in the Vital and Essential Drugs list), Endofalk - from 500 rubles, Fleet phospho-soda - from 1500 rubles. Undoubtedly, the classical scheme (using enemas) has the minimum cost, but with this method labor costs increase significantly, and such a scheme is much less comfortable for patients than taking modern means intended for high-quality preparation.*
