Persistent pain after surgery has significant physical and mental consequences for the patient, as well as a significant economic impact on health systems. Neuropathic pain is caused by direct or indirect damage to the somatosensitive system. In thoracic surgery, chronic neuropathic pain is represented by Post-Thoracotomic Pain Syndrome (PTPS), defined as recurrent or persistent pain in the thoracotomy scar site that persists for more than 3-6 months. Currently, in literature, the prevalence of PTPS is extremely variable. This prospective observational study aims to assess the incidence of pain in the weeks and months following surgery and to assess whether and how the presence of painful symptoms changes the patient's quality of life.
For each patient enrolled in the study, in the pre-operative phase, comorbidities, any chronic analgesic therapy and quality of life (through a dedicated questionnaire - Euro QoL 5D5L1) will be recorded. Surgical data (type of procedure, lobe affected by resection, type of approach and surgical time) and anesthesiological data (intravenous opioid, locoregional technique (s), non-opioid analgesics administered and other medications) will be collected in the perioperative phase. In the 48 hours following the surgery (in the Recovery Room, at 6h, 12h, 24h, 36h and 48h) the patient's pain data will be recorded (static, dynamic and cough-associated NRS) and those relating to any complications. The total amount of morphine administered to the patient in the first 48 hours will also be recorded. Each patient will be evaluated 7 days, 1, 3 and 6 months after the surgery by telephone interview. In this last phase, the possible presence of pain and its characteristics will be assessed, especially if these meet the criteria of neuropathic pain.

analysis of perioperative factors implicated in the onset of postoperative pain after chest surgery and the incidence of neuropathic pain
Cattinara Hospital
Trieste, Italy
RECRUITINGIncidence of persistent post-operative pain after thoracic surgery
The incidence of static, dynamic and cough-associated pain is assessed through the numerical rate scale (NRS), by a telephone interview one week and one month after surgery. A questionnaire is submitted to the patient to analyze the characteristics of the pain and its possible impact on the patient's quality of life.
Time frame: the data needed to analyze the incidence and characteristics of pain will be collected at 1 week after surgery
Incidence of persistent post-operative pain after thoracic surgery
The incidence of static, dynamic and cough-associated pain is assessed through the numerical rate scale (NRS), by a telephone interview one week and one month after surgery. A questionnaire is submitted to the patient to analyze the characteristics of the pain and its possible impact on the patient's quality of life.
Time frame: the data needed to analyze the incidence and characteristics of pain will be collected at 1 month after surgery
Incidence of Chronic Pain after thoracic surgery
The possible presence and incidence of chronic pain is assessed through a telephone interview three and six months after surgery.
Time frame: The data needed to analyze the presence of chronic pain will be collected at 3 months after surgery
Incidence of Chronic Pain after thoracic surgery
The possible presence and incidence of chronic pain is assessed through a telephone interview three and six months after surgery.
Time frame: The data needed to analyze the presence of chronic pain will be collected at 6 months after surgery
Presence of pain with typical features of neuropathic pain in the different phases of the postoperative course
During each telephone interview the presence of neuropathic pain is assessed through a dedicated questionnaire (PainDetect Questionnaire) and the impact that this type of pain has on the patient's quality of life.
Time frame: The data neede to analyze the presence of neuropathic pain will be collected at a week after the surgery
Presence of pain with typical features of neuropathic pain in the different phases of the postoperative course
During each telephone interview the presence of neuropathic pain is assessed through a dedicated questionnaire (PainDetect Questionnaire) and the impact that this type of pain has on the patient's quality of life.
Time frame: The data neede to analyze the presence of neuropathic pain will be collected at a month after the surgery
Presence of pain with typical features of neuropathic pain in the different phases of the postoperative course

Assessment of the incidence of chronic pain based on the different surgical techniques in thoracic surgery
the aim of this objective is to analyze whether different surgical techniques (more or less invasive) play a role in the onset of chronic pain after thoracic surgery
Time frame: during the intraoperative phase, data relating to the surgical techniques performed are collected
Assessment of the post-operative quality of life based on the different surgical techniques in thoracic surgery
the aim of this objective is to analyze whether different surgical techniques (more or less invasive) play a role in the quality of life after thoracic surgery
Time frame: during the intraoperative phase, data relating to the surgical techniques performed are collected
Evaluation of postoperative pain control based on different anesthesiological techniques and its possible correlation with the development of chronic pain
the aim of this objective is to analyze whether different anesthesiological techniques play a role in the onset of chronic or neuropathic pain after thoracic surgery. The techniques of locoregional anesthesia performed and the drugs used both during surgery and in the postoperative phase are analyzed
Time frame: data relating to this objective are collected in the intraoperative, 24 hours after surgery and subsequent telephone interviews at 1 week, 1, 3 and 6 months after thoracic surgery
