Heavyweight mesh is superior to lightweight mesh in laparo-endoscopic inguinal hernia repair. A meta-analysis and trial sequential analysis of randomized controlled trials. Ann Surg 2021; 273: 890-899.

Published: 1st November 2021

Authors: Bakker W, Aufenacker TJ, Boschman JS, Burgmans JP

Conclusion

This study included 12 RCTs. The risk of recurrence was greater after use of lightweight mesh (32/1571 procedures) than heavyweight (standard) mesh (13/1508 procedures), relative risk 2.21, 95 per cent confidence interval 1.14 to 4.31). There was no difference in pain or foreign body sensation.
