Postoperative pain is an important adverse event following inguinal hernia repair. The aim of this trial was to compare postoperative pain within the first 3 months and 1 year after surgery in patients undergoing open mesh inguinal hernia repair using either a self-gripping lightweight polyester mesh or a polypropylene lightweight mesh fixed with sutures.

Adult men undergoing Lichtenstein repair for primary inguinal hernia were randomized to ProGrip™ self-gripping mesh or standard sutured lightweight polypropylene mesh.

In total 557 men were included in the final analysis (self-gripping mesh 270, sutured mesh 287). Early postoperative pain scores were lower with self-gripping mesh than with sutured lightweight mesh: mean visual analogue pain score relative to baseline +1·3 and +8·6 respectively at discharge (P = 0·033 …
