Is chronic post-herniorrhaphy pain always chronic? A literature review
Department of Clinical Science, Intervention and Technology, Karolinska Institute, Huddinge, Sweden
Introduction: Chronic 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.
Methods: A literature review was undertaken, searching for studies with repeated estimates of post-herniorrhaphy pain. The hypothetical halvation time was calculated from the repeat estimates.
Results: Eight studies fulfilling the criteria were identified. With one exception, the extrapolated halvation times ranged from 1.3 to 9.2 years.
Discussion: Even 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.
Keywords: hernia, pain, chronic post-surgery pain, neuropathic pain, halvation time
