Dear Colleagues,

On behalf of the organising committee it is our great pleasure to invite you to join us in Barcelona a in 9th World Symposium on Lymphedema Surgery (9th WSLS) to be held in Barcelona on March 10th-11th, 2020.

Inspired by the success of the previous International Meetings on Lymphedema Surgery, we are fortunate to have the opportunity to host once again the World Symposium on Lymphedema Surgery.

This 9th Symposium will consist of two days of lectures, video surgery transmissions and breakout sessions. Current techniques will be presented with a clear focus on searching evidence and providing reliable results.

Controversy and cross-fire debates will be the major features of this meeting in order to get audience interactivity, to define practical consensus and to promote critic assessment on the hot topics.


It is truly a special event to have so many world leaders in lymphedema surgery, lymphedema research, lymphatic education and lymphatic system imaging, including David Chang, Ming Huei Cheng, Hakan Brorson, Joon Pio Hong, Isao Koshima, Takumi Yamamoto, Dhruv Singhal and many others, all in one place, sharing their experiences in this field that we are all so passionate about. Having so many national and international brilliant minds and years of experience all together provides the potential for a truly enjoyable and rich educational experience.

Barcelona is a dynamic and vital Mediterranean city and we are sure that you will enjoy your stay with us.

Yours sincerely,

D. Chang, M.H. Cheng, I. Koshima & J. Masià
WSLS Co-Chairmen
