    BackgroundInternational guidelines concerning mesh and mesh fixation options in laparoscopic totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) groin hernia repair are based on studies focusing on either mesh or fixation. We hypothesized that the value of such recommendations is limited by lacking knowledge on how mesh and fixation interact. The current registry-based nationwide cohort study compared different mesh/fixation combinations for relative risks for reoperation after TEP and TAPP groin hernia repair.Study DesignAll TEP and TAPP registered in the Swedish Hernia Registry 2005 to 2017 with standard polypropylene (StdPPM) or lightweight (LWM) flat mesh, having tack, fibrin glue, or no fixation, were included. The endpoint was reoperation due to recurrence as of December 31, 2018. Multivariable Cox regression rendered relative risk differences between the exposures, expressed as hazard ratios (HR) with 95% CIs.ResultsOf 25,190 repairs, 924 (3.7%) were later reoperated for recurrence. The lowest, mutually equivalent, reoperation risks were associated with StdPPM without fixation (HR 1), StdPPM with metal tacks (HR 0.8, CI 0.4 to 1.4), StdPPM with fibrin glue (HR 1.1, CI 0.7 to 1.6), and LWM with fibrin glue (HR 1.2, CI 0.97 to 1.6). Except for with fibrin glue, LWM correlated with increased risk, whether affixed with metal (HR 1.7, CI 1.1 to 2.7), or absorbable tacks (HR 2.4, CI 1.8 to 3.1), or deployed without fixation (HR 2.0, CI 1.6 to 2.6).ConclusionsWith StdPPM, neither mechanical nor glue fixation seemed to improve outcomes. Thus, for this mesh category, we recommend nonfixation. With LWM, we recommend fibrin glue fixation, which was the only LWM alternative on par with nonaffixed StdPPM.Copyright © 2022 The Author(s).
