About the department

The Department of Gastroenterology deals with the diagnosis, treatment and prevention of the organs of the digestive system. Every year, it carries out about 1,000 examinations of the internal surface of the colon, which allows for early detection of tumors in the colon. In 25% of these cases doctors diagnose polyps, which are removed without pain. In this field, the department has 40 years of experience. The department closely cooperates with other specialized departments of the clinic, which allows to work out the individual treatment program for each patient as precisely as possible. The department is headed by Dr. med. Peter Maure.

  • Diarrhea with enzyme deficiency (histamine, lactose,  fructose intolerance, etc.)
  • Bile acid loss syndrome
  • Gynsonococcal fistula
  • Nervous diarrhea
  • Parasitic diarrhea (Lamblia, Amoeba, M. Whipple, Trichiuren, etc.)
  • Paradoxical diarrhea in case of intestinal stenosis
  • Sprue syndrome
  • Toxic diarrhea (without pathogens, e.g. drug-induced)


  • Dysbacteriosis
  • Habitual constipation
  • Mechanical obstacles
  • Drugs or malnutrition

Indications for rehabilitation for the rehabilitation stay:

  • Complaints after gastrectomy or bowel removal
  • Chemotherapeutic follow-up treatment of gastrointestinal tumors
  • Functional and wound disorders after surgery on the liver / bile / pancreas
  • PEG or parenteral nutrition in severe malabsorption or palliative care
  • Treatment of pain due to chronic visceral hyperalgesia 

In addition, since recently the department has offered video capsule endoscopy of the large and small intestine. This examination method is especially useful if patients need non-invasive and safe screening for a colorectal tumor. Also, capsule endoscopy is an excellent alternative to conventional examination.

When examining the colon, the new method involves swallowing of a small capsule containing two chambers that remove the passage through the intestine. It captures up to 35 images per second, which allows an excellent assessment of the intestinal mucosa in a well-prepared colon. Polyps and other changes can be displayed in very good quality.

When examining the small intestine, a person swallows a capsule with miniature video cameras (slightly larger than a standard tablet), 26x11 mm in size. The video cameras produce approx. 80,000 images of the small intestine for 8 hours, after which they are sent to an electronic receiver, which patients wear on the waist belt.

Capsule endoscopy is excellent for diagnosing small intestinal diseases, especially in case of unclear bleeding from the gastrointestinal tract or for clarifying chronic anemia, if the previous gastric or colonoscopy has not been adequately explained. In addition, this method is used by default for inflammatory bowel disease and for suspicion of small intestinal tumors.

Compared to traditional radiological and endoscopic methods, this procedure has the following main advantages:

  • Simple and non-invasive alternative
  • Lack of contrast medium
  • Lack of sedation or anesthesia
  • Lack of radiation exposure
  • During the examination, the patient can live an everyday life without any restrictions
