Research Achievements

Field of Study

    Digestive surgery, Endoscopic surgery, Portal hypertension, Hepato-biliary-pancreatic surgery

Research Title

  • Expression of heat shock protein (HSP) and its role in the portal hypertensive gastric mucosa., Portal hypertensive gastric mucosa, which is called portal hypertensive gastropathy (PHG) can become a cause of gastrointestinal bleeding. An experimental study regarding PHG and heat shock protein (HSP) has never been reported. The aim of this study is to determine a relationship between HSP expression and hemodynamic and impaired changes in the gastric mucosa.
  • Establishment of dendritic cell immunotherapy as a postoperative adjuvant treatment for hepatocellular carcinoma., We previously performed a phase I study of autologous dendritic cell-based immunotherapy (DC therapy) in 10 patients with unresectable primary liver cancer from April 2000 (Iwashita Y, et al. Cancer Immunol Immunother 2003). The aim of this study is to determine effectiveness of DC adjuvant therapy in the postoperative patients with hepatoma and to establish the new treatment of DC immunotherapy.
  • Development of new endoscopic treatment: laparoscopic hepatectomy and pancreatectomy, Laparoscopic resection of liver and pancreas has not often been done. Laparoscopic hepatectomy and pancreatectomy were performed in 38 patients for recent 10 years in Department of Surgery I, Oita University. Laparoscopic resection of liver and pancreas may safely be done now, and further effectiveness of the operations should be examined in future.
