Abstract

In preparing for a lecture on the ethics of surgical complications, it became apparent that confusion exists about the definition of a ‘‘surgical complication.’’ Is it, as one medical website states, ‘‘any undesirable result of surgery?’’ [1]. In the European Journal of Surgery, Veen et al. [2] provide a more elaborate definition: ‘‘every unwanted development in the illness of the patient or in the treatment of the patient’s illness that occurs in the clinic’’ [2]. An esteemed historian of science suggests yet another definition in a recent volume on surgical complications: ‘‘a complication, in any sphere of endeavour, is something out of the norm, and the product of extraneous and unexpected factors’’ [3]. Such is the discrepancy in definitions that Rampersaud et al. [4] declared in 2006 that ‘‘presently, there is no clear or consistent definition of a complication in the surgical literature.’’ Much research in surgery aims to reduce the risk of surgical complications. However, until we have a stable and agreed definition of what counts as a surgical complication, we cannot reliably compare different studies to discover what best reduces the chance of surgical complications [5]. Therefore, the topic is more than mere pedantry; defining surgical complications will help us with the broader question of how to improve surgical practice. A basic PubMed search returned nearly 800 articles with the phrases ‘‘surgical complications’’ or ‘‘surgical complication’’ in the title. But unlike the sources above.
