About Prof. Dr Heiner Wedemeyer

Prof. Dr Heiner Wedemeyer is a specialist in gastroenterology and director of the Clinic for Gastroenterology, Hepatology, and Endocrinology at the Hanover Medical School.

Together with his highly-skilled team, Prof. Dr Wedemeyer 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.

Clinic for Gastroenterology, Hepatology, and Endocrinology – State-of-the-Art Diagnostics and Therapy

The Clinic for Gastroenterology, Hepatology, and Endocrinology at the MHH has state-of-the-art diagnostic and therapeutic services for patients with liver, stomach, and intestinal diseases as well as disorders of hormone metabolism In addition to inpatient care, patients are treated and cared for in numerous special outpatient clinics.

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 Clinic for Gastroenterology, Hepatology, 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.
