Message from the Head of the Department

     Hello everyone. Welcome to the homepage of the Department of Gastroenterology.
It has been three years, since I arrived for the post in April 2018. Since I took office, I set to work with reckless. The team members of this department also fully demonstrated their potential in the new structure and construct a solid foundation for the new regime. Thanks to that, I feel that the three pillars of clinical, educational and research, which are the missions of the medical university, have definitely progressed and evolved in the last three years. This is the fourth year, all the team members will make further efforts so that we can further enhance our progress so far and make a significant contribution to the development of community medicine, medical education, and medical research.
      Now, since the World Health Organization (WHO) issued a statement on January 9, 2020 regarding the new type of pneumonia caused by the coronavirus, the coronavirus sickness has continued for a long time. The spread of the coronavirus has had a great impact on our gastrointestinal disease treatment. Gastrointestinal endoscopy, which can be said to be the mainstay of gastrointestinal disease medical care, has been severely restricted under the state of emergency due to the high risk of aerosol generation, and the lack of personal protective equipment. Recently, all the team members are making efforts to provide good medical care to patients with the principle "Safe and secure medical treatment for digestive diseases in coronavirus pandemic" by utilizing various experiences and researches so far. If I want to express my team in a Japanese kanji character, I would choose "和(wa)". "和" has various meanings such as lessened, gentle, calm, familiar, friendly, congruity, match, and harmonic. I think that all of the meanings match perfectly with this team.
