Nikkei said Liêm performed Asia’s first laparoscopic surgery on a child. Commonly used on adults, the procedure involves making small incisions in the abdomen, but is more difficult to perform on children because their bodies are smaller, leaving less room to work.

In 2014, he became a pioneer in using stem cell transplants to treat serious disorders such as cerebral palsy.
