Pain
-
Persistent postsurgical pain (PPSP) is a frequent and often disabling complication of many surgical procedures. Nerve injury-induced neuropathic pain (NeuP) has repeatedly been proposed as a major cause of PPSP. However, there is a lack of uniformity in NeuP assessment across studies, and the prevalence of NeuP may differ after various surgeries. ⋯ In patients with PPSP after groin hernia repair, the prevalence of NeuP was 31%, and after total hip or knee arthroplasty it was 6%. The results suggest that the prevalence of NeuP among PPSP cases differs in various types of surgery, probably depending on the likelihood of surgical iatrogenic nerve injury. Because of large methodological variability across studies, a more uniform approach is desirable in future studies for evaluating persistent postsurgical NeuP.
