Department of Gastroenterology, Hepatology, Infectious Diseases and Endocrinology

The highly-skilled team of the Department for Gastroenterology, Hepatology, Infectious Diseases and Endocrinology offers patients with liver, stomach, and intestinal diseases a state-of-the-art range of diagnosis and treatment at the modernly equipped clinic. Because of the close cooperation with the other clinics and institutes of the Hanover Medical School and the Comprehensive Cancer Centre Lower Saxony, patients receive interdisciplinary care as needed. The focus is always on personalized care.


Research and teaching

Research and teaching is an important part of our clinic and is closely linked to clinical work. Both basic and clinical research is carried out in a large number of working groups. Employees of the clinic are involved in various research groups and cooperations. Clinical studies give us the opportunity to test new treatment methods, they form the basis for the broad establishment of new therapies. The transfer of existing knowledge and new findings within the framework of student training is important to us.

Hepatology and Liver Centre Hanover

Prof. Dr Wedemeyer is a proven liver specialist. The diagnostics and therapy of liver diseases are among his specialities. At the MHH Liver Centre, all procedures of liver and bile duct surgery are performed on children and adults. One of Prof. Wedemeyer’s main focuses is the hepatological treatment of acute and chronic liver diseases and the treatment of liver cancer that can lead to liver transplantation. Cancers of the liver, pancreas and gastrointestinal tract are treated on an interdisciplinary basis at the Comprehensive Cancer Centre of Lower Saxony. Another focus of Prof. Dr Wedemeyer’s work is the diagnosis and treatment of rare liver diseases (e.g. hepatitis D infection). The MHH is one of five German university hospitals in the “ERN-rare” network for rare liver diseases.

Congenital liver diseases are detected and treated with the help of sonography and interventional radiology as well as the most modern methods of genetic diagnostics. Treatment concepts (e.g. for monogenetically determined liver diseases using innovative gene therapy) are developed and established.

Endoscopy MHH – Modern Diagnostics

In the Department of Gastroenterology, Hepatology, Infectious Diseases and Endocrinology, standard endoscopic procedures such as gastroscopy, colonoscopy, and ERCP are routinely performed. By inserting the smallest probes equipped with cameras, it is possible to visualise the organs. If necessary, treatment can be carried out directly in the same session.

State-of-the-art, flexible, high-resolution endoscopes are used to investigate the gastrointestinal tract. At the tip of the endoscope is a camera that directly transmits images from inside the body to a monitor. Various instruments and tools can be inserted via a working channel to take samples or remove polyps.

The endoscopic operations are performed by experienced specialists. Through cooperation with other specialist disciplines, treatment at the highest level is guaranteed. In addition to common and special endoscopic methods, new therapeutic procedures are regularly developed and evaluated in clinical studies.

The examinations and operations are usually carried out under short anaesthesia (even in outpatients if desired) so that the patient is deeply asleep and experiences no pain during the endoscopy. The medication is administered and monitored by experienced and specially trained professionals.

Visceral Oncology Centre – Interdisciplinary Diagnosis and Treatment of Gastrointestinal Tumours

People with cancer of the intestine, liver, stomach, bile ducts, pancreas, and oesophagus receive the best care in all phases of the disease at the Visceral Oncology Centre Hanover.

Experienced specialists in visceral surgery, gastroenterology, hepatology, radiology, and radiotherapy work together on an interdisciplinary basis and can draw on the latest diagnostic and therapeutic methods for individual therapy planning. This interdisciplinary cooperation is supplemented by a close network of psychosocial care, nutritional counselling, specialist oncological care, wound and stomatotherapy, outpatient aftercare, and rehabilitation. This guarantees the best possible care of patients at the highest quality level.

The four general surgery wards have a total of 93 beds as well as four gastroenterological wards with a total of 80 beds, 10 therapy places in the gastroenterological-oncological day clinic and 5 additional treatment places in the visceral surgery polyclinic. The well-trained medical and nursing staff help ensure the success of therapy. Diagnostics as well as medical and surgical therapy are carried out according to the latest scientific findings and are individually tailored to the patient. The Visceral Oncology Centre Hanover also has an extensive range of new therapeutic agents for when standard therapies fail.
