Abstract

Mesh fixation is not routinely required in most laparoscopic inguinal hernia repairs (LIHR); however, when indicated, the optimal fixation method remains uncertain. This study aimed to compare surgical glue versus absorbable tacks (AT) for mesh fixation in LIHR, focusing on postoperative pain and early complications.
We searched PubMed, Embase, and Cochrane for randomized controlled trials (RCTs) comparing glue versus AT in elective LIHR. Effect estimates were pooled using random-effects models and expressed as mean differences (MDs) or risk ratios (RRs) with 95% confidence intervals (CIs). The primary outcome was postoperative pain assessed by the visual analogue scale (VAS). Secondary outcomes included complications and operative time. Risk of bias was assessed using the Cochrane RoB 2 tool. Trial sequential analysis (TSA) and prediction intervals (PI) were used to assess robustness.
Nine RCTs comprising 1,289 patients were included. Glue fixation was associated with lower early postoperative pain at 7-14 days (MD - 0.77; 95% CI - 1.22 to - 0.33; p < 0.001; I² = 83%). However, substantial heterogeneity and wide prediction intervals (- 2.33 to 0.79) indicated variability across settings. TSA suggested evidence of potential effect; however, this finding should be interpreted in the context of substantial heterogeneity. No significant difference was observed beyond 4 weeks, with insufficient cumulative evidence to draw firm conclusions. Glue fixation was associated with lower rates of hematoma and seroma, although the findings were uncertain given the prediction intervals and TSA. Other outcomes were underpowered or inconclusive.
Glue fixation may be associated with lower early postoperative pain than absorbable tacks after LIHR; however, the available evidence remains heterogeneous and inconclusive for other postoperative outcomes. Further adequately powered randomized trials are required before definitive clinical recommendations can be made.
