Gastroenterology and Hepatology Department

Message from the Director of the Department

The Department for Gastroenterological/Liver Internal Medicine is the new name for the former Department of Internal Medicine 1 because of reorganization undertaken by each organization. We specialize in all areas of gastrointestinal diseases represented by malignant diseases including gastrointestinal tract, liver, and biliary/pancreatic diseases, inflammatory bowel disease, H. pylori diagnosis (specialized outpatient), and diseases such as cholangitis, pancreatitis, hepatitis, and cirrhosis. We work on developing the pillars of our practice: high-quality medical treatment, research clarifying questions arising from clinical practices by conducting basic research and applying the results to clinical practices, and education to develop superior clinicians. Moreover, we attempt to provide optimum care to patients not only at our clinic, but also in close cooperation with related hospitals and practical doctors.

Features and Description of Medical Care

The Department of Gastroenterological Medicine specializes in gastrointestinal diseases, liver diseases, and diseases of the biliary tract/pancreas. Our endoscopic medical care includes providing endoscopic diagnoses with high precision and aggressive endoscopic treatment. We provide specialized outpatient service and medical service in cooperation with the Department of Bacteriology and Pathology for Helicobacter pylori infection. We are also introducing per-oral endoscopic myotomy ahead of other hospitals in the Chugoku and Shikoku regions for medical treatment. Our IBD center provides medical care for inflammatory bowel disease (ulcerative colitis, Crohn’s disease) and the latest specialized treatment in accordance with the condition of patients. For liver diseases, we have specifically examined the development and enforcement of novel therapies including clinical trials for the treatment of hepatitis B and C. We often carry out radiofrequency ablation for liver cancer, along with up-to-date treatments such as hepatic arterial infusion and molecular targeted drugs. For pancreatic carcinoma and biliary tract cancer, chemotherapy is often performed in cooperation with the Department of Surgery before and after surgery. In addition, biliary stenosis is frequently treated with endoscopic treatment such as stent indwelling and the removal of common bile duct stones.
