English: preparation for colonoscopy
A colonoscopy is a diagnostic measure in which the inside of the large intestine can be inspected and diagnosed with a flexible endoscope.
To prepare for the colonoscopy, the colon must first be cleaned laxative drug to take in
The instrument with which one Colonoscopy is carried out is called Colonoscope. It belongs to the group of endoscopes. A colonoscope is an endoscope specially designed for intestinal examination. This colonoscope consists of a partially flexible tube with a camera attached to the tip. It consists of flexible glass fibers that are approximately 10 micrometers in diameter.
A glass fiber strand is made up of approx. 40,000 individual fibers. One light and one color point is transmitted per fiber. From the tip of the colonoscope, the images captured by the camera can be passed along the fibers and made visible on a monitor. In addition to flexible endoscopes, there are also rigid endoscopes, which are primarily used for examinations of the Rectum be used because only a short distance has to be covered here. If, on the other hand, the entire colon is to be examined, a 1m -1.5 m long flexible endoscope required ..

In addition to the camera attached to the tip, there is also a cavity running along the hose through which a wire can be passed, with a small clamp at the tip. The clamp can be used to take tissue samples from the intestine during a colonoscopy. The clamp can be controlled from the outside during the examination. Furthermore, there is a very bright light on the tip of the colonoscope, which is intended to ensure a suitable view for the examiner during the diagnosis. Furthermore, air can be fed into the intestine via a colonoscope and fluid can be sucked out again.
In order to be able to perform a colonoscopy, the Intestines of the patient completely emptied and cleaned be.
If there are still food residues in the intestine, the examining doctor cannot assess the conditions in the intestine very well, as they can be seen by the camera or the view of the mucous membrane is only limited.
For this reason, it is very important that the patient follows a few dietary rules a few days before his colonoscopy so that the patient can have a cleaned intestines can come for examination.

It is necessary in advance laxative to take. There are many different laxatives that can be used in preparation for the colonoscopy, and the examining doctor will recommend a preparation to his patients.
The schedule for taking the laxative depends on the preparation chosen, but the basic process is mostly similar.
For the optimal effect of the laxative it is important that the day before the colonoscopy after breakfast nothing fixed more can be eaten.
The laxatives only work in combination with a lot of liquidwhy the patient drink a lot have to. This is often found to be very uncomfortable.
Most preparations require the first dose to be taken the evening before the examination (e.g. Moviprep®, Citrafleet®).
The laxative must be dissolved in water for this. The amount of water varies depending on the preparation a few milliliters up to 2-3 liters and can be found in the package insert.
The laxatives usually don't taste particularly good, so drinking them takes some effort.

The term Moviprep® is a laxative that is intended to cleanse the intestine, especially the large intestine, before a colonoscopy. So that the mucous membrane of the intestinal section to be examined can be examined properly, no residues of past food in the intestine must block the path.
One pack of Moviprep® is put into a total of 2 liters of water to obtain a solution. The administration and the procedure for taking it will be explained in advance by a doctor or pharmacist. The 2 liters of water, some of which are drunk the evening before the examination and some the next morning, should achieve a complete cleansing of the colon.
You have to expect that liquid stool will go off when you absorb the solution and should therefore stay near a toilet. After drinking Moviprep® and having a colonoscopy, the stool should normalize on its own.
However, side effects can occur in the form of abdominal pain (abdominal pain after colonoscopy), nausea, hunger, thirst and vomiting.
The use of Moviprep® is a standard procedure in everyday hospital life and is generally harmless.
However, if you have a number of pre-existing conditions, you should avoid Moviprep® and other laxatives. These include intestinal obstruction, allergies to ingredients and individual metabolic diseases.
An enema is the injection of liquid into the large intestine to clean the last section of the intestine.
In contrast to the laxative, the last section of the bowel is cleaned from behind. The enema, or "enema syringe", is used when other laxatives fail, when there are intestinal passage problems, in preparation for a colonoscopy or before operations.
Sometimes a colonoscopy has to be done spontaneously, whereby the enema is used to briefly cleanse the intestine. Subsequent diarrhea and liquid stool can also be expected here.
