Thank you for visiting the website of the Department of Gastroenterology at the University of Tokyo Hospital. I am Mitsuhiro Fujishiro, and as of July 1, 2021, I have taken over the role of overseeing this department, succeeding Professor Masao Omata, the first Chair, and Professor Kazuhiko Koike, the second Chair.

The Department of Gastroenterology primarily deals with a wide range of diseases affecting the gastrointestinal tract (esophagus, stomach, small intestine, large intestine), as well as the liver, biliary tract, pancreas, and spleen. Under the motto "Science in Gastroenterology with Technology and Compassion," approximately 100 highly motivated physicians are dedicated to patient care, cutting-edge medical research, and the training of the next generation. In patient care, our team of cool-headed specialists, with a burning passion inside, works closely with medical staff such as nurses, pharmacists, dietitians, and medical clerks to ensure the best possible treatment.

We also focus on research. The gastrointestinal system, our area of expertise, is not only essential for digestion and nutrient absorption but also plays a crucial role in endocrine metabolism and immunity. It has been found to be central to the interplay between various organs, including the brain-gut axis. Therefore, I believe that by unraveling the unknown phenomena occurring within the gastrointestinal system, we can contribute to the prevention and treatment of not only gastrointestinal diseases but also a wide range of other conditions.

Therefore, in my specialized field of gastrointestinal endoscopy, I aim to lead the world by advancing endoscopic diagnostics from morphology-based disease pathology observations to the observation of life phenomena. Additionally, I seek to evolve endoscopic treatments from techniques focused on tissue destruction and resection to those aimed at the restoration and transplantation of cell and tissue functions. Ultimately, my goal is to develop methods for disease prediction and prevention as well as aging control. To this end, I welcome the support of young physicians so that we can contribute to the well-being of patients around the world, including those we do not have the opportunity to examine directly, and help protect the happiness of healthy individuals.
