Investigation of the Frequency of the Development of Chronic Pain After Thoracotomy

Background: Chronic pain following thoracotomy remains a common and clinically significant complication that adversely affects functional recovery and quality of life. Despite advances in perioperative analgesic techniques, chronic post-thoracotomy pain continues to be under-recognized and insufficiently managed in routine clinical practice. In this study, we aimed to determine the incidence of chronic pain after thoracotomy and evaluate its impact on daily activities and postoperative pain management behaviors. Methods: This retrospective observational study was conducted after institutional ethics committee approval was received (approval no. 2023/61). Patients aged ≥15 years who underwent thoracotomy between 15 June 2022 and 15 June 2023 and had undergone an operation at least three months prior to the study were included. Patients who underwent video-assisted thoracoscopic surgery were excluded. Demographic, surgical, anesthetic, and postoperative analgesia data were obtained from medical records. Patients were contacted by telephone to assess pain intensity using a Numeric Rating Scale (NRS), functional impact on daily activities, and analgesic medication use. The primary outcome was the incidence of chronic post-thoracotomy pain, defined as pain persisting beyond three months and reported at the time of the interview. Results: A total of 56 patients were included in the analysis. Chronic pain was reported by 55.4% of the patients. Pain that interfered with daily activities and required medication use was reported by 51.5% of the patients. Thirty-three patients (57.9%) reported an NRS score > 3 during movement. Among patients with chronic pain, 64.7% reported self-medication without physician consultation, whereas only 11.8% sought medical advice for pain management. Conclusions: Chronic pain remains highly prevalent after thoracotomy and substantially interferes with daily functioning. A considerable proportion of patients self-manage their pain without medical supervision, underscoring the need for structured postoperative follow-up, early identification of high-risk patients, and individualized multimodal analgesic strategies to reduce the burden of chronic post-thoracotomy pain.
