title: [How does a surgeon decide that surgery is the best option?Assessing whether or not to operate].
abstract: All abdominal surgical procedures have a certain risk/benefit ratio. Recently, the way surgeons come to a decision whether to operate, or not, was discussed in the Annals of Surgery. First, the assessment of the decision for an operative versus a non-operative strategy was addressed on the basis of clinical vignettes. The perceptions concerning risk/benefit balance varied considerably between surgeons and these perceptions predicted the decision to operate. In a second paper, surgeons were randomized to either an arm in which they were exposed to a risk calculator or to a control arm. The decisions of the risk-calculator arm were less varied, but did not alter the likelihood of recommending an operation. Perhaps surgeons decide to operate or not rather intuitively, based on clinical and laboratory information. Alternatively, they may consider the statistically significant difference in risk/benefit to be less relevant. A better insight into surgeons' decision making and the way in which they weigh benefits against risks is very useful, but it is proving to be a considerable research challenge.
