title: [Patient's individuality and application of guidelines in surgery].
abstract: Individual treatment decisions can become considerably conflictual in view of the co-existence of medical professional guidelines, recommendations based on evidence-based medicine (EBM), and juridical and economical directions. Medical guidelines are not subject to an external review process; also, due to reduced practicability, the surgeons' compliance with guidelines remains relatively low. Surgical treatment strategies can rely on randomized clinical trials (RCTs) in approximately 20% of the surgical procedures and on non-randomized trials in approximately 70% of the cases. No evidence is given in approximately 10% of the cases. Specific problems of implementation of EBM in surgical disciplines are represented by the difficulty of standardized procedures, the heterogeneity of the population, the impossibility to conduct double-blinded RCTs, a low statistical power, and a publication bias. Since individual diseases cannot be reduced to surgical cases manageable only by the application of guidelines, adequate treatment of individual patients requires the critical application of both external evidence and surgeon expertise (internal evidence).
