Chronic postsurgical pain (CPSP) is defined as pain persisting for longer than 3 months postoperatively. The frequency of occurrence ranges from 5 % to 60 % in all types of surgery and 1-3 % of patients with CPSP will suffer from severe pain and pain-related interference with daily activities. The pathological mechanisms which lead to the development of CPSP are complex and have not yet been analyzed. ⋯ Peripheral and central sensitization are the essential mechanisms of the development of pain chronicity in the postoperative period. As treatment of CPSP is demanding it is attempted to prevent central sensitization before CPSP develops. New scientific findings on the development of CPSP, perioperative risk factors and the potential of preventative interventions are discussed.

AbstractChronic postsurgical pain (CPSP) is defined as pain persisting for longer than 3 months postoperatively. The frequency of occurrence ranges from 5 % to 60 % in all types of surgery and 1-3 % of patients with CPSP will suffer from severe pain and pain-related interference with daily activities. The pathological mechanisms which lead to the development of CPSP are complex and have not yet been analyzed. Neuropathic pain after surgical nerve lesions has been reported. Many patients with CPSP, however, do not present with any neuropathic pain characteristics. Peripheral and central sensitization are the essential mechanisms of the development of pain chronicity in the postoperative period. As treatment of CPSP is demanding it is attempted to prevent central sensitization before CPSP develops. New scientific findings on the development of CPSP, perioperative risk factors and the potential of preventative interventions are discussed.
