IntroductionChronic post-surgery pain (CPSP) has gained increased recognition as a major factor influencing health-related quality-of-life following most surgical procedures, in particular following surgery for benign conditions. The natural course of CPSP, however, is not well-known.MethodsA literature review was undertaken, searching for studies with repeated estimates of post-herniorrhaphy pain. The hypothetical halvation time was calculated from the repeat estimates.ResultsEight studies fulfilling the criteria were identified. With one exception, the extrapolated halvation times ranged from 1.3 to 9.2 years.DiscussionEven if CPSP is generally very treatment-resistant, in many cases it eventually dissipates with time. Further studies are required to evaluate the prevalence of pain beyond the first decade.
