2021 Board of Directors

VICE President (2021-2022)

Nicholas J. Shaheen
University of North Carolina, USA

I am a gastroenterologist and professor of medicine at the University of North Carolina School of Medicine, and Chief of the Division of Gastroenterology and Hepatology at UNC. I specialize in endoscopic treatment of precancerous and cancerous conditions of the esophagus, and am an active clinical researcher in these areas. I am a longstanding member of the ISDE and support its mission. The unique multidisciplinary and international nature of the group provides a perspective not found elsewhere, and leads to enriched and stimulating academic interaction. I have enjoyed serving as a co-chair of the planning committee for our upcoming virtual Congress, and addressing the challenges presented by mounting a meeting in the time of a pandemic.

I have extensive administrative experience, both at my institution and in professional organizations, which make me well-suited for this position. In addition to managing our GI division and the clinical research center here at UNC, I have served as the Director of the American College of Gastroenterology Institute, the research and education arm of the ACG. I have also been a trustee of that organization for the past decade. I also served the American Gastroenterological Association as head of the Clinical Practice section, and a member of AGA Council. I am highly collaborative and believe that the best ideas to engage a professional society usually originate from the membership up, not the leadership down. I am honored to be considered for this position, and if selected, will work hard to promote the ISDE in national and international venues.


csde dIRECTOR (2021-2023)

Long-Qi Chen
West China Hospital, China

First of all, it is a great honor for me to be nominated for the period of 2021-2022 as Director of the ISDE Board.

Being an active member of ISDE since 1994, I attended most of the ISDE conferences since 1998. It was a significant experience for me to witness the growing and strengthening of ISDE, now to be the most representative and impacted societies in the world. As for China, I founded Chinese Society for Diseases of the Esophagus (CSDE) in 2015 in order to improve the current unsatisfactory quality of medical care. The Society is focused on improving the medical service quality by enhancing medical education and training, bridging international collaboration and coordinate clinical studies.

As one of the 2 affiliated societies to ISDE, CSDE represents a combined initiative amongst Chinese surgeons, physicians, pathologists and scientists to study esophageal diseases. Later on, we promoted over 120 abstracts submission and 90 attendees to ISDE 2016 in Singapore. It would be the similar expectation for ISDE 2018 in Vienna. What’s more, the “CSDE Annual Working Conference 2020 ” was successfully held in Shenzhen, China. It brought together multiple specialties focused on the clinical management and research of patients with esophageal diseases. Since its inception, CSDE has been playing as an excellent platform for the academic exchange of clinical and scientific knowledge on the latest developments.

I am willing to initiate or chair some task forces assigned by ISDE, already with experience with being enrolled in the WECC task force to define the 7th and 8th edition of TNM staging for esophageal cancer. I am keeping communication and also serving in other local relevant societies in China like Esophageal Cancer Committee, Chinese Anti-Cancer Association (CACA), and Esophageal Expertise Committee, Chinese Association for Thoracic Surgeons (CATS).


ESDE Director (2021-2023)

Magnus Nilsson
Karolinska Institutet, Sweden

I am professor of surgery and head of the Division of Surgery at the Department of Clinical Science, Intervention and Technology at Karolinska Institutet in Stockholm, Sweden.

My clinical work is mainly dedicated to esophageal and gastric cancer surgery, but I also do quite a bit of benign esophageal work, including hiatal hernia repair and management of esophageal perforations and airway fistulas. My main scientific interests are oriented towards optimizing management of esophageal cancer patients, with a particular interest in neoadjuvant therapies and tailoring of lymphadenectomy and minimally invasive surgical techniques.

I am the past President of the European Society for Diseases of the Esophagus, the Swedish Society of Upper Abdominal Surgery and currently the Chairman of the Swedish National Registry for Gastric and Esophageal Cancer. I have a particular interest in multidisciplinary collaboration, and I am much involved in several oncological associations, for example as a faculty member of the upper gastrointestinal group of the European Society for Medical Oncology (ESMO) and a member of the European Organization for Research and Treatment of Cancer (EORTC) gastrointestinal group. As a result of many years of multidisciplinary collaboration I have led and currently lead some international randomized multicenter trials in the crossroads of surgery and oncology, such as the completed NeoRes I and II trials and the currently ongoing NEEDS trial.

I am also an associate editor of Diseases of the Esophagus since 2015 and the work with our great journal is something that I consider extremely important and always try to prioritize. I would be very happy and honored if I would be given the chance to serve as a director in the ISDE board and I would then take the opportunity to work hard to further develop multidisciplinary and international collaboration in the interests of the ISDE.
