Detailed thought, knowledge, complex analysis, reasoned judgment and professionalism all fundamentally underpin a surgeon's work and training, yet there is a popularly held view that accomplished surgeons are primarily concerned with performing procedures. A review of pedagogical, social and medical literature, together with personal reflections from the authors, shows that a surgeon's work is multi-faceted. This article discusses the technical skills of operating as a reflection of the 'tip of the iceberg' of a surgeon's cognition, the increasingly multidisciplinary strategic approach of surgeons today, the importance of surgical decision making, the influence of robotics, the role of non-medically trained staff, surgeons' role in postoperative care, adaptive expertise and the formation of professional identity. In so doing, a much wider view of a surgeon than simply 'doing' or 'thinking' is presented with implications for surgical training.
