At this conference, we focused on “the theme of nutrition-related disorders and digestive system,” as emerging common disorders in Asia-Pacific region. It includes a variety of aspects, not only topics relating to nutritional deficiency, but also including emerging topics which relate to nutritional excess, such as obesity or non-alcoholic fatty liver disease (NAFLD). Because such disorders are important public health issues, a review of the current practice for these diseases specific to the Asia-Pacific region is timely and has drawn our scientific interest very much. Around 120 participants attended the 3rd APTC meeting. The meeting started with an evening seminar. During the conference beginning on November 2, distinguished researchers representing Asian-Pacific societies gave plenary lectures including presentation of their recent data and information on the current situation in their countries. There were also two luncheon seminars and poster presentations by 34 active researchers. Best poster awards, which were selected on the basis of scores of the program committee members, were given to the four best posters presentations. The conference was a great success, and all the participants enjoyed the friendly atmosphere during the 2-day meeting. We were able to exchange the most recent information, and we thought that this conference was very much helpful for providing an opportunity to deepen friendship among different field of specialists, those include gastroenterologists, hepatologists, physiologists, and surgeons. I wish to express great appreciation to Professor Kentaro Sugano, president of the JSGE, and Professor Khean Lee Goh, president of the APAGE, for their kind consideration and help for this joint meeting. I hope that this proceeding will be helpful for exchanging the latest information on the important issues in the Asia-Pacific region and also play a great role in sending a lot of valuable new information to all over the world.
