Endoscopy

High-resolution dermatoscopic mole screening, minimally invasive outpatient minor surgical procedures, and comprehensive dermatological care from infancy through adulthood.

Endoscopy services

Advanced gastrointestinal diagnostics and comfortable examinations under anesthesia

Endoscopic examinations are among the most accurate and informative diagnostic procedures in gastroenterology, allowing physicians to directly examine the inner lining of the digestive tract in high resolution. During the procedure, a flexible instrument equipped with a camera and light source (an endoscope) is introduced into the digestive tract. This enables physicians not only to identify abnormalities in the mucosal lining but also to perform painless tissue sampling (biopsies) for histopathological examination and certain therapeutic procedures, such as polyp removal.

What to know before your examination

Our goal is to ensure that your procedure is performed as safely and comfortably as possible, with minimal waiting times and stress. Whether you are scheduled for an examination under anesthesia or while awake, please review these essential preparation guidelines to help ensure an accurate and effective diagnostic procedure:

What should you know before your appointment?

  • Preparing for gastroscopy (upper endoscopy): The examination generally requires strict fasting for 6 hours beforehand, with no food or liquids, to ensure that the stomach lining can be clearly visualized.
  • Preparing for colonoscopy: Thorough cleansing of the colon is essential. This requires carefully following the prescribed bowel preparation protocol and drinking the special laxative solution as instructed on the day before and the day of your examination.
  • Requirements for anesthesia: If you choose to undergo the examination under anesthesia, a prior anesthesiology consultation is required. You must also arrange for a responsible adult to accompany you home safely after the procedure.

When is an endoscopic examination recommended?

Gastroscopy or colonoscopy may be recommended to investigate gastrointestinal symptoms or as part of preventive screening in the following situations:

  • Gastroscopy (upper endoscopy) is recommended for: Persistent heartburn, acid reflux, burning pain in the upper abdomen, difficulty swallowing, unexplained nausea, black stools, or suspected Helicobacter pylori infection.
  • Colonoscopy is recommended for: Blood in the stool, alternating diarrhea and constipation, persistent bloating, lower abdominal cramps, unexplained weight loss, or monitoring previously diagnosed inflammatory bowel conditions such as Crohn's disease or colitis.
  • Preventive screening (age 50 and older): Colonoscopy is strongly recommended for colorectal cancer screening, even in the absence of symptoms, particularly if there is a family history of colorectal cancer or colon polyps.

Available examinations

At our premium medical centers in Buda, Pest, and Újbuda, we perform endoscopic procedures using state-of-the-art imaging equipment and comprehensive anesthesia support.

Gastroscopy (upper endoscopy)

Gastroscopy is an endoscopic examination of the esophagus, stomach, and duodenum (the first part of the small intestine).

How is it performed? The patient lies on their left side. A local anesthetic spray is applied to the throat to reduce the gag reflex. The examination can also be performed under light sedation for additional comfort. The endoscope is gently inserted through the mouth. The procedure typically takes just 5–10 minutes.

When is it recommended? Gastroscopy is recommended for patients experiencing persistent heartburn, acid reflux, difficulty or pain when swallowing, unexplained nausea, vomiting, abdominal pain, unexplained weight loss, or iron deficiency anemia. It is also an important diagnostic procedure when celiac disease, a gastric ulcer, or Helicobacter pylori infection is suspected.

Precise internal diagnostics and the key to cancer prevention

Direct endoscopic visualization is essential to reliably detect the issues behind digestive symptoms—such as inflammation, ulcers, bleeding, or precancerous polyps. Advanced optical equipment not only reveals even the smallest mucosal changes, but also allows your doctor to take immediate action, collect biopsies, and remove polyps on the spot.

We make your comfort our top priority. With gentle sedation, a private and relaxed environment, and dedicated medical attention, we ensure your procedure is smooth and stress-free—laying the groundwork for an accurate diagnosis and effective recovery.

If you struggle with frequent heartburn, unexplained stomach pain, or are 45 or older, don't put off getting checked. Book an appointment with our specialist team for a clear diagnosis and proactive colon cancer screening.

Key specialties and diagnostic areas:

Upper endoscopy (Gastroscopy)

  • Detailed examination of the esophagus, stomach, and duodenum
  • Clear diagnosis of acid reflux, esophagitis, stomach ulcers, and hiatal hernias
  • Helicobacter pylori detection via rapid on-site tests or tissue samples
  • Painless biopsies whenever needed to rule out serious conditions

Colonoscopy

  • Thorough and gentle check of the rectum and the entire large intestine
  • Detection and immediate, painless polyp removal (polypectomy)
  • Assessing and staging inflammatory bowel disease (Crohn's, ulcerative colitis)
  • Colorectal cancer screening to catch and treat issues early

Sedation and supportive care

  • Safe, light IV sedation overseen directly by an anesthesiologist
  • Pre-procedure medical review to ensure everything is completely safe
  • Seamless teamwork with our gastroenterology and surgery departments
  • Dedicated multilingual coordinators guiding you from preparation to recovery

Frequently asked questions

Common questions about endoscopy and colonoscopy procedures.

Yes. With gentle intravenous sedation administered by an anesthesiologist, you remain asleep throughout the procedure. You will not feel any pain, discomfort, or gagging. After waking up, you can rest comfortably in our recovery room for a short observation period before heading home.

Yes. Combining both procedures into a single appointment is very common and convenient. This allows your doctor to thoroughly examine both your upper and lower digestive tract under one sedation session and with just one prep period.

The examination itself takes only 15 to 30 minutes. If you have sedation, please plan for check-in beforehand and about 1 to 2 hours of rest in our recovery room afterward. Once you are fully awake and cleared by our team, an adult escort can accompany you home.

Not automatically, but if your gastroenterologist notices signs of inflammation, an ulcer, or any tissue irregularities, they will take a tiny, painless biopsy. Analyzing these samples in the lab is essential for an exact, reliable diagnosis.

For people at average risk with no symptoms, screening is recommended starting at age 45 to 50. If results are normal, you generally only need to repeat it every 10 years. However, if you have a family history of colon cancer or polyps (especially in a parent or sibling), you should start by age 40—or 10 years earlier than the age your family member was diagnosed—and repeat the screening every 5 years.

International clinical guidelines recognize colonoscopy as the gold standard because it does two vital jobs at once: it spots potential issues with high accuracy and allows your doctor to find and remove precancerous polyps during the very same visit.

In Europe, routine upper endoscopy isn't generally used as a general population screening tool for people at average risk. It is primarily recommended for people without symptoms who have a strong family history of stomach cancer or previously diagnosed precancerous conditions (such as Barrett's esophagus or chronic atrophic gastritis). In these cases, your gastroenterologist will establish a personalized follow-up schedule.
