The concept of "nodal points" describes a structured surgical procedure that is aimed at surgeons that are training to learn laparoscopic surgery. These instructions were realized in the form of so-called operation primer. We prepare medical writing, graphics, and sets of primers on the basis of surgical videos and instructions provided by surgeons. We have prepared a total of 14 primers since 2005 for all major laparoscopic procedures. Some of them are also available as eBooks.
