Developing new surgical methods was something that high-ranked hospitals were willing to do, and it was also something that they must do. 

New surgical methods meant new instruments and equipment, new projects and funding, new training and advanced studies, new allies and representatives… 

Developing new surgical methods could eliminate old surgical methods, then the hospital could progress according to the research direction recognized by the new leader and department director. It did not only reduce the impact of old-school doctors but also lower the burden on old surgical methods to be successful.
