Up to 6-7% of patients who have undergone laparoscopic groin hernia repair suffer from chronic pain, depending on various factors; however, the long-term course is unclear. The purpose of this study was to assess the prevalence of chronic pain 1-5 years after laparoscopic groin hernia repair.
The subjects of this nationwide cross-sectional questionnaire study were adults who underwent laparoscopic mesh repair of an inguinal or a femoral hernia. The patients were identified from the Danish Hernia Database, which has a follow-up rate of almost 100%. The prevalence of chronic pain was assessed 1-5 years postoperatively by the validated inguinal pain questionnaire (IPQ).
A total of 1383 groins were included in this study, based on a 66% response rate to the questionnaire. The prevalence of pain decreased, especially 3.5 years postoperatively. There were no statistically significant differences when each postoperative year was compared with the second postoperative year. However, the prevalence of chronic pain 3.5-5 years postoperatively was significantly lower (4.4%) than that 1-3.5 years postoperatively (8.1%) (p = 0.014). The prevalence of pain that could not be ignored was still 5-6% in the fifth postoperative year.
The prevalence of chronic pain seems to decline 1-5 years after laparoscopic groin hernia repair, with a distinct decrease 3.5 years postoperatively.
根据各种因素，接受腹腔镜腹股沟疝修补术的患者中，高达6%-7%会遭受慢性疼痛；然而，其长期病程尚不清楚。本研究的目的是评估腹腔镜腹股沟疝修补术后1至5年慢性疼痛的发生率。
这项全国性横断面问卷调查研究的对象是接受腹股沟或股疝腹腔镜补片修补术的成年人。患者从丹麦疝数据库中识别，该数据库的随访率几乎为100%。术后1至5年，通过经过验证的腹股沟疼痛问卷（IPQ）评估慢性疼痛的发生率。
基于问卷66%的回复率，本研究共纳入1383个腹股沟疝病例。疼痛发生率下降，尤其是术后3.5年。将术后各年份与术后第二年进行比较时，无统计学显著差异。然而，术后3.5至5年慢性疼痛的发生率（4.4%）显著低于术后1至3.5年（8.1%）（p = 0.014）。术后第五年，不容忽视的疼痛发生率仍为5%-6%。
腹腔镜腹股沟疝修补术后1至5年，慢性疼痛的发生率似乎有所下降，术后3.5年有明显下降。
