How long does an endoscopy take?
This depends on the location, i.e., the section of the gastrointestinal tract to be examined, and whether it is a purely diagnostic or also a therapeutic examination. A purely diagnostic gastroscopy normally takes around 15-30 minutes and also includes an assessment of the duodenum and esophagus. A colonoscopy, for example for preventive purposes, takes 20-40 minutes. If any procedures need to be performed, the examination time will be longer.

- Insurance card
- Previous findings from other doctors
- Diagnosis list
- List of medications

When is an endoscopy indicated?
As a preventive measure, a colonoscopy is recommended for everyone aged 50 and over, regardless of whether they have any symptoms and/or illnesses. This procedure removes lesions that could later develop into cancer, thereby prolonging life. If there are warning signs (e.g., unintentional weight loss), an endoscopy is recommended as soon as possible, regardless of age.
An upper endoscopy (examination of the esophagus, stomach, and duodenum: esophagogastroduodenoscopy) should be performed in cases of bloody vomiting and persistent symptoms such as difficulty swallowing or vomiting. A colonoscopy is indicated in cases of blood in the stool or chronic diarrhea. However, even in patients without warning signs, an endoscopic examination can be useful and valuable as part of the diagnostic process. This may be the case, for example, in cases of digestive problems that persist despite taking antacid medication.
What is an endoscopy and how is it performed?
Endoscopy means "seeing inside," i.e., it is an examination of the inside of the body, the gastrointestinal tract. During an endoscopy, a flexible tube (endoscope) is inserted into the digestive tract through the mouth or anus. The latest generation of endoscopes enables excellent assessment of the mucous membrane with outstanding light and image quality and 4K resolution. Depending on the examination, special endoscopes with different lengths and additional functions (e.g., linear endosonography) are used along the entire length from the mouth to the anus.

Is an endoscopy painful?
Endoscopic examinations are not normally painful. You may experience some discomfort or a feeling of pressure from the air insufflated when the endoscope is inserted through the mouth or anus after the examination.
How should one prepare for an endoscopic examination?
The colon must be cleansed before a colonoscopy. We ask that you drink the recommended medication to prepare your colon at the specified times before the examination. You should also drink 1 liter of a clear liquid of your choice. Before the colonoscopy, you should avoid raw vegetables, raw fruit, and high-fiber foods (e.g., whole grain products, legumes such as beans and lentils) for three days. We will provide you with detailed instructions before the examination.
Can gastroscopy and colonoscopy be performed in a single examination?
A combination of gastroscopy and colonoscopy is always possible and is a very efficient procedure for clarifying unclear symptoms.
Can complications arise during endoscopies?
Yes. Normally, diagnostic and therapeutic endoscopic examinations proceed without problems and as originally planned. Complications during purely diagnostic endoscopies are very rare and usually not serious. Mild side effects such as nausea, vomiting, or abdominal pain are treated with infusions, and the patient can go home without any complaints. Moderate complications such as bleeding or tears in the mucous membrane can usually be treated and cared for during the examination. Serious complications such as perforations, which require laparoscopy or other surgical or medical treatment, are extremely rare. Even in these cases, injuries can often be repaired with the endoscope. However, clinical monitoring after such an event is still necessary.

Do I need to fast before an endoscopy?
You must have an empty stomach for an endoscopy:
This means that you must not eat any solid food for 6 hours. You must not drink any liquids for 2 hours before the examination. For a colonoscopy, there are additional dietary rules that you must follow in the days leading up to the examination.
Will I need someone to take me home after the endoscopy?
To make the examination as comfortable and safe as possible for you, we usually administer a sedative to our patients before and during the endoscopy. This allows us to achieve optimal examination conditions. As your reaction time may be impaired for up to 24 hours after the examination, you must not drive any motor vehicles for 24 hours. You should also refrain from entering into any legal transactions. If you have traveled to the hospital privately, you will need someone who is fit to drive to accompany you on your journey home. Alternatively, we recommend traveling to and from the hospital by public transport.
When can I eat and drink again after an endoscopy?
After a purely diagnostic gastroscopy or colonoscopy, you may eat and drink again immediately after the examination. We will serve you a light snack in a relaxed atmosphere. Special examinations and interventions require a short-term adjustment to your diet. Your doctor, Dr. Schlosser, will inform you of this after the examination.
When can I expect the results?
Once you are sufficiently awake after the examination, your doctor, Dr. Schlosser, will talk to you and explain the findings of the examination. If tissue samples were taken during the endoscopy, these must first be stained and examined under a microscope in the pathology department. In most cases, the results are available after 3-4 working days.
Why do we offer the use of CO2 gas during colonoscopy?
In order to obtain a clear view during colonoscopy, it is essential to distend the colon with gas. This is usually done using room air, which is insufflated into the intestine via the endoscope in quantities of up to 15 liters per examination. Since room air is poorly absorbed by the intestinal mucosa, this air remains trapped in the intestine. Many patients therefore report at least unpleasant, often painful flatulence and abdominal cramps when they wake up after the examination. Although this is ultimately a medically harmless occurrence, many patients remember this time after the examination as unpleasant. For this reason, we use CO2 during colonoscopy. Carbon dioxide (CO2) is absorbed by the colon mucosa 150 times faster than room air. The insufflated CO2 gas is then transported to the lungs with the blood, just like the CO2 that is continuously produced in the body throughout life through combustion processes, and exhaled unnoticed. The aforementioned flatulence and abdominal pain after colonoscopy are now a thing of the past.
Which preventive examinations are advisable if colorectal cancer runs in the family?
If there are no symptoms, the first preventive examination should be carried out 10 years before the age at which the disease occurred in other family members. Regular colonoscopies every 5 years are recommended in cases of familial clustering. In cases of polyposis syndromes (FAP, aFAP, MAP), you will need to consult a specialist.
