History of Japan Biliary Association

The Japan Biliary Association (JBA) was initially founded as “Cholecystography Study Group” in November 1965. This catalyzed a momentum toward a national-level conference on cholecystography. The 2nd Study Group Meeting was held in Tokyo on August 6, 1966, and about 100 physicians gathered and debated vigorously. Since then, the meeting has become an annual event. It was renamed “Biliary Diseases Study Group” at the 5th Meeting held in Fukuoka and to “Japan Biliary Diseases Study Group” at the 18th Meeting in Tokyo, to widen the discussion issues of biliary diseases. During these periods, the Study Group grew into a large-scale association with larger numbers of study participants, presentations, and Study Group members.

The discussion on transiting from the Study Group to the JBA started at the 20th Japan Biliary Diseases Study Group Council Meeting in 1984, with over 2,000 members. In December 1985, a questionnaire “the JBA Draft Constitution” was sent to all Study Group members and further discussions continued after their feedback. On March 27, 1986, the Extraordinary Council Meeting for the Japan Biliary Diseases Study Group approved the JBA Constitution, and on August 22 of the same year, the 22nd Japan Biliary Study Group Council Meeting approved the transition to the JBA. On the same day, the 1st Council Meeting of the JBA was held, where the history of the association’s establishment was reported; the Chair, Vice-Chair, and officers were elected; the 1987 budget was approved; and the association was inaugurated.

The 1st Annual Meeting of the JBA was held on August 21 and 22, 1987, in Hirosaki City, Aomori Prefecture. Since then, the meeting has convened annually.
