Abstract
In surgery (as in other disciplines of medicine) a causal therapy is connected with a causal diagnosis. Many physicians confine themselves to symptomatic measures which are useless beyond self-healing or introduce some kind of poly-pragmasia. Sometimes between those extreme positions there is a need of deliberations "as if" or primarily diagnostic operations. Diagnostics as a whole consist of logical as well as of psychological elements. Approximation is made either by some kind of hypothetico-deductive calculations or using some kind of pattern recognition. Anamnesis and immediate personal examination yield a preliminary diagnosis in about 80%. Yet a diagnosis of this sort has to be verified or falsified by scientific methods. The final decision is a function of both the theory of probability and the theory of utility. The combination is demonstrated by the so-called decision matrix and the so-called decision tree, going from simple models to complicated ones.
