Clinic for Gastroenterology

‘Our department’s mission is to detect and treat diseases of the internal organs. The patient, with his or her individual concerns and complaints, is always the focus of all our efforts.’
(Provisional Chief Physician Dr. med. Michael Mullen)

The Clinic for Gastroenterology treats patients with diseases of the gastrointestinal tract and of the liver. The responsibilities also include problems with the endocrine glands (endocrinology) and diseases of the kidney (nephrology). Certified by the German Diabetes Society (DDG – Deutsche Diabetes Gesellschaft), this treatment facility also specialises in diabetes mellitus, together with all of the problems associated with the disease; together with the Clinic for Cardiology, it covers the entire spectrum of internal medicine.

Abdominal pain, jaundice, weight loss, diarrhoea or internal bleeding are only some of the symptoms treated in the Clinic for Gastroenterology. The mission also extends to viral and bacterial diseases (infectology) and problems with the lungs (pneumology). In the context of treatment of cancer (oncology), since 2012, the Municipal Hospital of Pirmasens has met the stringent requirements of a colorectal centre. An interdisciplinary tumour conference is held on a weekly basis.

Interdisciplinary treatment concepts are created thanks to dovetailing with the Clinic for General and Abdominal Surgery, specialists in private practice as well as national centres of excellence. In addition to its specialities, the Clinic for Gastroenterology offers a comprehensive treatment spectrum for General Internal Medicine.


GastroenterologieThe Clinic for Gastroenterology covers a broad spectrum in the field of Internal Medicine. In additional to General Internal Medicine, the emphases here are on diagnostics and treatment of complaints of the digestive and metabolic organisms as well as infectiological and malignant diseases. Patients with acute and chronic kidney failure are treated through a cooperation arrangement with MVZ Nephrocare in Pirmasens; this includes execution and initiation of procedures in haemodialysis. A large Central Endoscopy department permits not only routine diagnostics but also emergency interventions – round the clock and without delay. Patients with diabetes mellitus receive optimal support and consultation by diabetologists and diabetes consultants during their stay.

Patients benefit from a holistic treatment approach based on proven partnerships in a cooperative system among the disciplines, general practitioners and specialists as well as secondary facilities.

Very great importance is attached to the training and continuing training of medical staff. At the same time, the Clinic for Gastroenterology offers a variety of seminars and workshops and presents the results obtained at scientific congresses.

Ambulante EndoskopieEndoscopy offers extensive possibilities for diagnosis and treatment. It is also gentle on the patient, much less unpleasant than often thought, as well as largely unproblematic and low-risk. In an entire array of endoscopic possibilities, gastroscopy is the most common outpatient examination, alongside the colonoscopy.

Upon referral by physicians working in endoscopy, for instance, outpatient examination appointments are arranged with the patient through the secretariat of the Clinic for Gastroenterology. The examinations are regularly preceded by informed-consent discussions where, among other things, physician and patient discuss the precautions to take in terms of medications and diet prior to the treatment. All preparatory measures aim to make the examination as safe and pleasant as possible for the patients, but also to make the results themselves more meaningful as well.

Prior to the examination, the physician and patient discuss whether a (usually useful) brief anaesthesia is desired or required. In this case, an accompanying person should certainly be enlisted to collect the patient after the examination, particularly since a patient will not be able to operate a motor vehicle at all on the day of the examination. Following the examination, all sedated outpatients are cared for in a recovery room, looked after by medical specialists and appropriately monitored.

Inpatient treatments in the Clinic for Gastroenterology are typically made following medical referral. The patient or the referring physician phones in to register the patient through the secretariat. Naturally, medical emergencies are admitted round the clock via the outpatient service.

If at all possible, the following things should be brought along:

  • Health insurance chip card or declaration of cost coverage of the private health insurance scheme
  • Card exempting the patient from payments, together with receipts documenting deductible amounts already paid
  • Identity card
  • Physician’s referral slip

By the time of the medical consultation and the admission examination, the following things should be in hand (if available):

  • Recent findings of examinations or X-ray images
  • Medical information, doctor’s letters relative previous hospital stays as well as pre-existing conditions and operations
  • Vaccination certificate and emergency pass
  • Overview of medications regularly taken
