[The "BTE"(basic knowledge--training--execution) method for teaching-learning surgical procedures].
For teaching-learning operative procedures the authors propose a new method ("KTE" method) in three progressive phases (step "K" or "basic knowledge"; step "T" or "training"; step "E" or "execution") that allow the student to achieve gradually the psychomotorial adaptation needed for the correct execution of surgical procedures. After preliminary study of the general features of the procedure (step B1) the student learns its operative features (step B2) on appositely constructed didactical tools ("Self-learning and learning maintenance boxes") that, together with the "observational" training (step A1), allow him to create in his mind an "operation image" and then, following an "operative" simulators training (step A2), to pass from that image to its carrying out (psychomotorial adaptation) that in the last phase (steps E1 and E2) concludes in the partial or complete execution of the surgical procedure in the patient. This didactic method can be apply to classic or endoscopic surgery and even to a lot of not surgical practical procedures.
