Abstract
The 49th annual meeting of Japan Biliary Association was held on September 19-20, 2013 at Chiba wih the main thema " Challenge for Innovation in Professionalism". In the presidential address I told five different sections as follows. 1. The history of biliary tract diseases and biliary surgery. 2. The history of percutaneous biliary cholangiography and the contribution of our department to its development 3. Recent clinical and experimental research of our department in biliary surgery 4. Professinonalism for physician and Challenge for innovation 5. The memory of Japan Biliary Association and acknowledgement I would like to talk about the attitude of " challenge for innovation" as academic physician from my personal experiences. The importance of these attitudes was addressed for especially young doctors in the audience. I have always kept this attitude in the clinical practice and research work from post-graduate time to the present time. I hoped to demonstrate the medical implications of this attitude, " Challenge for Innovation" for all physician's who have faced to the patients.
