In 2011, Sergelen and her team of surgeons did the first successful liver transplantation in Mongolia at the First Central Hospital of Mongolia. Her team had done test surgeries on 26 pigs for three years. Since then, her team has done 47 liver transplantations in Mongolia. Recognizing that liver cancer is the most prevalent and economically disastrous cancer in Mongolia, Sergelen led the development of low-cost liver transplants in Mongolia. Now liver transplants cost MNT 10-15 million (around US$3–5 thousand). She proposed that Mongolian state health budget cover all liver transplantations. Now the state budget covers 75 percent of all liver transplantations in Mongolia.

Sergelen earned a Bachelor of Medicine (BM) in 1982, a Master of Clinical Medicine (MM) in 1983, a Doctor of Medicine (MD) in 1997, and a Doctor of Philosophy (PhD) in 2002 from the Mongolian National University of Medical Sciences (MNUMS). She completed medical fellowships in developed countries such as South Korea, Switzerland, USA, and Finland.

Sergelen taught surgery at the Mongolian National University of Medical Sciences from 1982 to 2002. In 2002, she became the Head of the Surgery Department there, and she holds this position to present date.
