Enhanced vs.Standard Pain Management of Patients at Risk for Chronic Post-surgical Pain

The goal of this pragmatic pilot clinical trial is to test the feasibility of the trial in terms of the number of patients recruited in a given period. The main question it aims to answer is to assess the number of eligible patients and number of patients willing to participate per month. Participants will be followed either by the team of "transitional pain service" (intervention group) or by a surgeon or the general practitioner (standard care). Depending on individual risk factors, patients in the intervention group will be offered some targeted measures, for example: * hypnosis, * patient education, * evaluation by psychiatrist, * psychotherapy, * locoregional anesthesia, * anti-depressant treatment Participants (in both intervention and standard care groups) will be asked to answer some questions before surgery, during the first week following the surgery and six months after the surgery.
