About us

Prof. Heiner Wedemeyer is a specialist in gastroenterology and hepatology in Essen. Here, he is the Medical Director of the Department of Gastroenterology and Hepatology at the University Hospital, Essen. In addition to the treatment of inflammatory and viral diseases of the liver and the gastrointestinal tract, Prof. Wedemeyer in Essen also focuses on liver transplants. Prof. Wedemeyer was the head of the workgroup that developed the national S3 guidelines on hepatitis B, hepatitis C and hepatocellular carcinoma and a panel member of various European Clinical Practice Guidelines of the European Liver Society (EASL). In addition, he currently holds the position of Medical Director of the Liver Foundation GmbH Germany, which has established the German Hepatitis C Register, which with more than 13,000 patients represents one of the largest "real-world cohorts" for hepatitis C therapy worldwide. Prof. Wedemeyer was involved in more than 100 Phase I to IV studies as coordinator of the hepatitis outpatient department at the Hanover Medical School for many years, where he not only acted as Principal Investigator but also as Head of the Clinical Trial for Germany (LKP). As an expert in gastroenterology and hepatology, Prof. Wedemeyer also carries out liver replacement procedures for tumors, endoscopies of the gastrointestinal tract or minilaparoscopies as well as midilaparoscopies (keyhole technique).

Using these techniques, Prof. Wedemeyer is able to treat particular conditions such as inflammatory and viral liver diseases (hepatitis A - E) or chronic inflammatory intestinal diseases. In addition, Prof. Wedemeyer's clinic treats all diseases of the visceral organs including the liver, esophagus, stomach, intestines and pancreas, such as gastrointestinal tumors (HCC, CCC), liver cancer, pancreatitis, reflux disease, diseases of the bile ducts and colitis ulcerosa. Another special area of focus is the liver transplantation, whereas the preparation and evaluation of the transplantation as well as the long-term aftercare takes place in the clinic of Prof. Wedemeyer.

As a maximum care gastroenterology and hepatology centre, Prof. Wedemeyer’s clinic covers the entire spectrum of gastroenterology and hepatology. All diagnostic, endoscopic, interventional endoscopic and sonographic (ultrasound) techniques are utilised in the Endoscopy Department of the University Hospital, Essen and approximately 10,000 examinations are performed annually. In addition to a general gastroenterology clinic, the Department’s Out-patients’ Clinic under the gastroenterology specialist, Prof. Wedemeyer, also holds specialist clinics for liver and biliary tract diseases, chronic inflammatory bowel diseases, functional gastrointestinal conditions, diseases of the pancreas and gastroenterological tumors, particularly hepatocellular carcinoma. A large proportion of the patients of the specialist in gastroenterology hepatology is referred by hospitals or private medical practitioners from outside the Essen metropolitan area. Increasingly, in recent times, this includes patients with advanced liver diseases, including acute and chronic liver failure, for further clarification with regard to a liver transplant.
