Incidence and risk factors of chronic post-thoracic surgery pain: A retrospective study.

Background: Chronic post-thoracic surgery pain (CPTSP) is a common complication that affects a patient's quality of life. Thoracotomy is associated with a high risk of chronic pain. Video-assisted thoracoscopy surgery (VATS) is a less traumatic option, but its role in the development of CPTSP is unclear.
