5th Congress of International Advanced HBP Surgery – Since 2017, we have been organizing the international advanced liver and pancreas symposium every year. The previous ISLS symposiums mainly focused on invited lectures, however, ISLS is now capable of hosting the congress with the fully diverse scientific program, including the free paper presentation sessions. The official name of the regular meeting will be changed to “The Congress of International Advanced HBP Surgery” We will change the annual symposium to a biennial congress and will organize small conferences in Seoul or Asia in the year when the congress is not held. “The 5th Congress of International Advanced HBP Surgery” will be held, the first of which will be in Zurich, Switzerland in 2023. Since it is a biennial congress, the congress after that will be held in 2025. In year 2024, we plan to consider hosting a two-day symposium in one of the Asian countries.
