The Asian Society of Transplantation (AST) was formed in 1981 when the charter members met at the annual congress of Asian Society of Nephrology (ASN).
The objectives of the Society are defined as:
• Promotion of exchange of information relating to transplantation
• Development of medical, biological and social disciplines in transplantation in Asia
• Cooperation in the training at all levels of professional involvement – nursing, transplant coordinator, pharmacists, physicians, surgeons and other disciplines involved in transplantation.
The Asian Society of Transplantation is a platform to provide assistance and help and plays an important role in the development of transplantation in the region.
It serves as a forum for doctors and scientists involved in the field of transplantation to exchange views, present research findings and develop networks for mutual benefit through its biannual conferences.
The AST also has future plans to help and assist its member countries to develop and make further progress in organ transplantation, progress in related research and form a network for organ exchange through a central registry.

Established in 1966, The Transplantation Society (TTS) serves as the principal international forum for the advancement and development of both the science and clinical practice of transplantation throughout the world. Its mandate is fulfilled through scientific communication, continuing education of its membership and guidance on the ethical practice of transplantation. The Transplantation Society is a Non-Governmental Organization (NGO) in official relations with the World Health Organization, and is composed of over 6500 professionals including but not limited to, physicians, surgeons, scientists and allied health professionals in 105 countries. TTS is one of two parent organizations of the Declaration of Istanbul, the other being the International Society of Nephrology. In addition, TTS has nine Sections specializing in solid organ and cell transplantation, including VCA. TTS also partners with 35 national and regional transplant societies from around the world.

TTS is delighted to endorse the 5th International LDLT meeting in Brussels in October 2021 in support of living liver donor transplant for altruistic, non-directed living unrelated transplants. TTS does not support commercial transplants.

The International Association of Surgeons, Gastroenterologists and Oncologists (IASGO) was founded in Amsterdam in 1988. Today, IASGO is a vibrant, strong and influential body of surgeons, gastroenterologists, and oncologists from over 90 different countries worldwide and with over 1,700 members. We are proud that our members include leading international personalities in the field of GI diseases as well as a younger generation of doctors who share our philosophy and are eager to learn. Through the Annual World Congress of IASGO, CME Post Graduate Courses all over the world, the official journals of IASGO (Surgery Gastroenterology & Oncology), and the IASGO website, we keep moving forward to achieve our mission: “Globalization of Medical Knowledge”.
