Message from the Professor

Since I became a Professor of the Faculty of Medicine, Hiroshima University, in September, 2000 and the head Professor of the Division of Gastroenterology of Hiroshima University Hospital in April 2002, our laboratory has evolved steadily as the result of the hard work of its doctors, staff and graduate students in the field of medical examination, education and research. We really appreciate the support of persons concerned with these activities.

The gastrointestinal tract, which includes many organs such as the esophagus, stomach, small intestine, colon, liver, gallbladder and pancreas, is our target area of practice, and many patients suffer from diseases affecting these organs. Our mission is to provide state-of-the-art treatment, to develop new therapies and to graduate splendid doctors by providing education to medical students and junior doctors in this area.

We mainly practice endoscopic diagnosis and endoscopic therapy of the gastrointestinal tract, diagnosis and therapy of chronic hepatitis and hepatic carcinoma and do medical examination of a wide range of diseases such as inflammation and carcinoma of the biliopancreatic duct or fatty liver and hyperlipidemia, which are related to metabolism. More cases of diagnosis and therapy are made in our hospital than in local hospitals. Moreover, we do various types of research in this area. The research is divided into two categories. One is clinical research, in which data from patients are analyzed. The other area is basic research, which involves laboratory experiments. We conduct basic research so that we can apply results to clinical research and try to develop new therapies. The results have been reported in academic papers and publications. The latest papers have been published in high-impact-factor journals highly recognized in this area worldwide. Many presentations have been made at international conferences. The practices and research at our laboratory are well recognized globally.

While we do diagnosis and therapy, we continue to cultivate doctors who can play an important role as physicians in Gastroenterology. Though the number of new members of our laboratory has been decreasing since the introduction of a new training system, we still welcome more than 10 new members a year on an average. We would not deny that we are busy, as we have a lot of goals to accomplish. However, we are motivated and have fun. We expect that more people will become interested in our work and want to work together with us.
