Chronic postsurgical pain

Chronic Postsurgical Pain (CPSP) is a clinical picture persisting for at least three months following a surgical intervention, where additional particular neuropathic symptoms are observed. The problem may also be defined as a long-term “acute neuropathic pain”.It is thought that between 10-50% of individuals can develop chronic post operative pain after common operations such as groin hernia repair, breast and thoracic surgeries, leg amputation, and coronary artery bypass surgery.CPSP develops through complex unclear mechanisms. Various mechanisms are responsible for the different pain syndromes, even following the same Operation. For instance, phantom pain, stump pain and back pain following lower limb amputations.Knowing the pain become chronic is always difficult. It is pain that is unlikely to get better, or that lasts longer than the usual healing time or it is pain that lasts a certain time for example, 3 or 6 monthes. In pain after surgery there is an added problem because many patients have had their surgery to treat apainful condition such as gallstones or a disk problem.it is important to know is the pain simply a continuation of the old pain or it is new. And even if it is new is it related to surgery or not? Sometimes it is obvious that something has changed for example nerve damage after operation for gall stones is quite different from the original pain. Sometimes it is very difficult to disentangle the pains, especially if the patient original pain (that the surgery was designed to treat) wasn’t in fact helped by the surgery; however, it is possible to list features of chronic post surgical pain:• The pain developed after surgical operation.• The pain lasts for at least 2 months.• Other causes of pain such as infection or cancer are not present.• The pain is not that type of pain which continues from the patient original condition.
