Chronic pain following inguinal hernia repair surgery is one of the key concerns in clinical practice. The causes of postoperative chronic pain include surgical techniques, mesh usage, and patient-related factors. Laparoscopic surgery is more effective in reducing the incidence of chronic pain compared to open surgery. Additionally, patient factors such as gender and age significantly influence pain perception and recovery. Therefore, adopting individualized treatment strategies is crucial. Approaches such as psychological therapy, pharmacological treatment, local anesthetic blocks, and microwave ablation have shown positive effects, while surgical interventions can also help alleviate pain symptoms. Future research should further explore the detailed mechanisms of postoperative chronic pain and develop more accurate predictive models to identify high-risk patients for effective preventive measures. Moreover, advancements in surgical materials and techniques, along with optimized pain management strategies, will play a crucial role in improving postoperative recovery quality and reducing pain symptoms.
