About

The main objective of this study is to establish the postoperative "pain pathways" observed from D1 to D7 in the context of the current management after orthopedic, digestive, obstetrics and gynecology, urology, neurosurgery, vascular and thoracicn surgeries.

Full description

The secondary objectives of this study are:

A. To assess the incidence of Post-Surgical Chronic Pain (PSCP) Chronic 3 months post intervention.

B. To asses the incidence of neuropathic type pain (DN4 Questionnaire) at 3 months post intervention.

C. To study the potential links between pain trajectories and the presence or absence of PSCP.

D. To study the potential links between the presence or absence of PSCP and known risk factors for PSCP (patient-related data, data on the surgery, anesthesia data).
