Chronic post surgical pain (CPSP) has lately become a neglected phenomenon.
Chronic post-surgical pain (CPSP) is one of the most common and serious complications after surgery. There is no universally agreed definition of CPSP; however, the working definition proposed by Macrae and Davies is commonly used . CPSP is associated with increased analgesic use, restriction of activities of daily living, significant effects on quality of life, and increased health-care utilization.
CPSP is not only observed following major surgery, but also following minor surgical procedures, such as hernia and vasectomy.
Nerve injury during surgery has been implicated in the development of CPSP; some (but not all) patients with CPSP have neuropathic pain. Therefore, any link between nerve damage during surgery and the development of CPSP is complicated. Not all patients with nerve damage develop CPSP, and those who do develop CPSP do not necessarily have neuropathic pain.
Chronic postoperative pain is followed after common operations, such as groin hernia repair, breast and thoracic surgery, leg amputation, and coronary artery bypass surgery.
