Dr. Lloyd Douglas (L.D.) MacLean
Dies at 90; Legendary Surgeon, Researcher and Professor

Published in February 2015 Issue             

Dr. Lloyd Douglas (L.D.) MacLean, a surgeon from Canada, credited with the country’s first lung transplant in 1966 (along with Dr. D.D. Munroe), a noted researcher on host resistance and shock, and a pioneer in bariatric surgery, died on January 14 at the age of 90.

Dr. MacLean was born in Calgary and graduated from the University of Alberta Medical School in 1949. He served as surgeon-in-chief at the Royal Victoria Hospital in Montreal from 1962 to 1988 and was chairman of the McGill University Department of Surgery from 1968-1973, 1977-1982 and 1987-1988. Dr. MacLean was editor-in-chief of the Canadian Journal of Surgery from 1972 to 1992. He was appointed an Officer in the Order of Canada in 1985 in recognition of his major contributions to medicine.

According to press reports, Dr. MacLean published more than 350 papers in peer-reviewed journals. He served as president of The American Surgical Association in 1992 and the American College of Surgeons in 1993. In 1996 Dr. MacLean gave the Mason Lecture at the ASMBS annual meeting on “Advances in the Treatment of Obesity.”

Michel Gagner, MD, FRCSC, FACS, FASMBS Clinical Professor of Surgery, FIU Senior Consultant, Hopital du Sacre Coeur in Montreal, was chief resident when Dr. MacLean was surgeon-n-chief at the Royal Victoria Hospital.

“If it had not been for him I would never have gotten into laparoscopic bariatric surgery,” said Dr. Gagner. “He was a great teacher and mentor, and was interested in bariatric surgery when no one was interested in bariatric surgery. He brought great scientific rigor to the field.”

Philip Schauer, MD, past president of the ASMBS, and director of the Cleveland Clinic Bariatric and Metabolic Institute, was also influenced by Dr. MacLean.

“Professor MaClean was one of those rare luminaries in bariatric surgery who made tremendous contributions to the field over the span of four decades from the 1960's to 2000,” said Dr. Schauer. “Key contributions included seminal papers tabulating long-term results of gastric bypass using scientifically rigorous methodology. One of his biggest contributions in my opinion was his leadership in advocating bariatric surgery as an academic discipline worthy of scientific study during a time when bariatric was not so well regarded in academia. Perhaps his greatest legacy was the hundreds of McGill surgical residents who he trained in bariatric surgery, many of whom became some our most outstanding contemporary leaders. He was a great man, surgeon, and educator, and did leave behind a remarkable legacy. We'll all miss him.”
