Abstract：
BACKGROUND: The impact of laparoscopic inguinal hernia repair (IHR) on chronic groin pain (CGP) prevalence, risk and daily activities compared to open IHR is still unclear.
METHODS: A meta-analysis of randomised controlled trials comparing CGP rates in laparoscopic and open IHR was performed.
RESULTS: 22 trials were included. CGP prevalence decreases significantly 1-2 years post-op and reaches rates as low as 4.69% (laparoscopic) and 6.91% (open) at >5 years. There is a significantly lower risk of CGP following totally extraperitoneal (TEP) than open mesh repair at all follow-up periods (p < 0.05) except for >5 years (p = 0.32). The same trend is not seen when compared to open non-mesh repair or for transabdominal pre-peritoneal repair (TAPP). There is no difference between techniques when CGP is described as moderate and/or affecting daily activities (p = 0.08).
CONCLUSIONS: CGP rates continue to decrease at >5 years follow up. TEP consistently results in a reduction in CGP rates compared to open mesh repair however, this is not functionally significant.

摘要：
背景：腹腔镜腹股沟疝修补术（IHR）对慢性腹股沟疼痛（CGP）患病率的影响，与开放IHR相比，风险和日常活动仍不清楚。
方法：对比较腹腔镜和开腹IHR的CGP发生率的随机对照试验进行了荟萃分析。
结果：纳入22项试验。术后1-2年，CGP患病率显着下降，在5年后达到低至4.69％（腹腔镜）和6.91％（开腹）。在所有随访期间（p<0.05），除>5年（p=0.32）外，完全腹膜外（TEP）后的CGP风险均明显低于开放网孔修复（p<0.05）。与开放式非网孔修复或经腹腹膜前修复（TAPP）相比，没有看到相同的趋势。当CGP被描述为中度和/或影响日常活动时，技术之间没有区别（p=0.08）。
结论：CGP率在随访5年后继续下降。然而，与开放网格修复相比，TEP始终导致CGP率降低，这在功能上并不重要。
