Background:The use of glue to fix mesh instead of sutures in Lichtenstein inguinal hernia repair has been accepted worldwide, with the increasing worries about postoperative chronic groin pain and recurrence. The aim of this meta-analysis was to clarify which mesh fixation method was more suitable in Lichtenstein inguinal hernia repair.Methods:Articles published up to July 2017 were searched using MEDLINE, the Cochrane Library, Embase, and the Web of Science. Randomized controlled trials (RCTs) comparing glue versus suture mesh fixation in Lichtenstein inguinal hernia repair were included in the review. The quality assessment and data extraction of included studies were applied by 2 independent authors. Statistical analysis was performed using RevMan 5.2 software.Results:Thirteen RCTs with 2375 patients were eligible for inclusion. Eight trials compared synthetic glue with suture fixation and 5 compared biological glue with suture fixation. The results showed that there was a lower incidence of early chronic pain (subgroup analysis, biological glue versus sutures, odds ratio (OR) = 0.41; 95% confidence interval (CI), 0.19–0.90; P = .03), and hematoma (subgroup analysis, synthetic glue versus sutures, OR = 0.56; 95% CI, 0.34–0.95; P = .03) in the glue fixation group. Suture mesh fixation method cost more time in operation than glue (mean difference = −4.60, 95% CI −7.60 to −1.60; P = .003). There was no evidence of an increase in chronic pain or recurrence rates with glue fixation method in the long-term follow-up.Conclusions:Mesh fixation with glue compared with sutures in Lichtenstein repair inguinal hernia is faster and less painful, without an increasing in terms of recurrence rates in the long term.
