Bio & Research

Is the Founder of AIS Channel (, a new approach to the communication of advances in cutting-edge surgical expertise, provided by renowned surgeons.

Professor Lacy and his team are global pioneers in the use of innovative minimally invasive technology in gastrointestinal cancer and metabolic syndrome and morbid obesity. He published in 2002 the first randomized study to prove the safety and feasibility of the laparoscopic approach vs the open approach for the treatment of digestive cancer, with excellent oncologic results. Professor Lacy’s team was also the first to perform a Total Mesorectal Excision (TME) by Transanal Approach on a patient in 2009, and have since improved the technique by using 3D imaging. Professor Richard J. Heald, the creator of the TME, the gold standard treatment in rectal cancer, supports this new approach as providing better oncologic outcomes than the conventional approach.

His main areas of interest are currently Transanal ColoRectal Endoscopic Surgery (TACRES) (taTME, Transanal Proctectomy in IBD & Transanal Approach in Hartmann’s Reversal), the robotic approach to colorectal and esophageal pathologies and the use of the last technologies and new surgical innovations such as the use of indocyanine green in all its applications (vascular perfusion, lymphatic mapping, metastasis identification….), visualization in 3D and currently in 4k. Professor Lacy participates in several international working groups, such as the international registry of transanal TME (led by Dr. Roel Hompes). He has performed over 700 taTME cases to date, and has chaired numerous TaTME courses all over the world. He is also member of international multidisciplinary working groups for bariatric surgery, type 2 diabetes, and Metabolic Syndrome.

Professor Lacy is the founder of AIS Channel (, the main global platform for surgical teaching, which seeks to bring surgeons from every corner of the world closer to the key opinion leaders and to the latest surgical innovations and technologies.

Professor Lacy and his team’s clinical and research work has resulted in more than 230 publications, with an accumulated impact factor of 889,641 (SCI Journal Citation Reports 2018) and a Hirsch Index of 50. He has also participated in 30 surgical reference book chapters and has been invited to deliver more than 400 lectures in congresses all over the world.

Professor Lacy is member of and has been actively involved in international societies such as SAGES (Society of American Gastrointestinal and Endoscopic Surgeons), ASCRS (American Society of Colon & Rectal Surgeons), EAES (European Association of Endoscopic Surgeons) where he was President from 2007 to 2009, and ESA (European Surgical Association). He was elected Honorary Fellow of the American Association of Colorectal Surgeons (ASCRS) in 2013, he was awarded the SAGES International Ambassador Award in 2017 and he has been selected as a 2019 Honorary Fellow of the American College of Surgeons.
