Coping with the unexpected at surgery

In lung cancer surgery, it is best to avoid surprises; this requires knowledge of the reliability of preoperative assessment and careful planning. If this has been done, most of the more common situations should be manageable. If there is limited chest wall, mediastinal or N2 node involvement, one should proceed with resection. Unanticipated T4 tumors or bulky pN2 disease should not come as a surprise, and such patients should be sent to a more experienced center. One has to be careful to practice within the scope of one’s knowledge and abilities as well as the sophistication of the institution. It only makes a mistake worse if an intraoperative surprise prompts one to embark on an operation that is beyond the means at hand. Collaborative organization via multidisciplinary tumor boards or inter-institutional interaction allows collective wisdom to promote better outcomes for all.
