Is chronic post-herniorrhaphy pain always chronic? A literature review

Insights
Chronic post-surgery pain (CPSP) often improves over time, though it can be resistant to treatment. This study found pain dissipation times ranging from 1.3 to 9.2 years for post-herniorrhaphy pain.
Area of Science:
- Pain Medicine
- Surgical Outcomes
- Quality of Life Research
Background:
- Chronic post-surgery pain (CPSP) significantly impacts health-related quality of life after surgical procedures, especially for benign conditions.
- The long-term natural trajectory of CPSP remains poorly understood.
Purpose of the Study:
- To investigate the natural course and resolution time of chronic post-surgery pain (CPSP).
- To estimate the time it takes for post-herniorrhaphy pain to dissipate.
Main Methods:
- A systematic literature review was conducted to identify studies reporting repeated pain estimates after herniorrhaphy.
- Pain halving times were calculated using available repeat pain estimates.
Main Results:
- Eight studies met the inclusion criteria for the review.
- Calculated pain halving times, with one outlier, ranged from 1.3 to 9.2 years, indicating eventual pain dissipation.
Conclusions:
- While often treatment-resistant, CPSP can eventually resolve over extended periods.
- Further research is needed to determine CPSP prevalence beyond ten years post-surgery.
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.
