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.
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。
