Abstract    Objective    To investigate the clinical factors and preventive measures related to chronic pain after tension-free hernioplasty. Methods    The clinical data of 229 cases of  tension-free hernioplasty performed from July 2011 to June 2013 in Department of General Surgery，the First Affiliated Hospital of China Medical University were analyzed retrospectively. Results    Among 229 cases, the incidence rate of chronic pain after 1 year was 8.7%. The incision infection (χ2=3.048；P=0.048) , using of lightweight meshes（χ2=11.223；P=0.001） and preoperative pain（χ2=9.181；P=0.002） were correlated with chronic pain after tension-free hernioplasty. Cox regression analysis revealed preoperative pain as an independent risk factor of chronic pain (P=0.010) Conclusion    The preoperative inguinal pain and postoperative incision infection are the risk factors of chronic pain after tension-free hernioplasty, while the using of lightweight meshes can reduce the incidence of chronic pain.

摘要：

目的    探讨影响无张力疝修补术后慢性疼痛的临床相关因素及预防措施。方法    回顾性分析2011年7月至2013年6月中国医科大学附属第一医院普通外科对229例腹股沟疝病人行无张力疝修补术的临床资料。结果    229例病人术后1年慢性疼痛发生率为8.7%。术后慢性疼痛与术后切口感染（χ2=3.915；P=0.048）、轻质补片应用（χ2=11.223，P=0.001）及术前腹股沟区疼痛（χ2=9.181，P=0.002）有关。多因素分析显示术前术区疼痛是术后慢性疼痛发生的独立危险因素。结论    术前腹股沟区疼痛和术后切口感染是术后慢性疼痛的危险因素，术中使用轻质补片可以减少术后慢性疼痛的发生。
