Backgrounds:
To compare the clinical effectiveness of different mesh fixation techniques in Lichtenstein tension-free repair using network meta-analysis.
Methods:
Cochrane Library, Medline, EMBASE, and Web of Science databases were searched until 1 December 2020, and randomized controlled trials (RCTs) comparing outcomes between different mesh fixation techniques were included. The primary endpoints were chronic postoperative inguinal pain (CPIP) and hernia recurrence. The second endpoint was seroma and infection. Data were processed using Stata MP16.0, and R x64 3.6.1.
Results:
The results demonstrated that 32 RCTs (n = 6362) were eligible for pooling. Six types of mesh fixation techniques were used: non-absorbable suture, absorbable suture, chemical glue, fibrin glue, self-gripping mesh, and staple fixation. Network meta-analysis indicated that the incidence of CPIP with fibrin glue was lower than that with non-absorbable sutures (relative risk [RR] = 0.23, 95% credibility interval [95%CrI] [0.09, 0.50]), absorbable sutures (RR = 0.24, 95%CrI [0.08, 0.60]), chemical glue (RR = 0.36, 95%CrI [0.13, 0.87]), and self-gripping mesh (RR = 0.27 95%CrI [0.09, 0.62]). Self-gripping mesh was superior to non-absorbable sutures (RR = 0.44, 95%CrI [0.23, 0.74]) in reducing postoperative infection.
Conclusion:
This network meta-analysis suggests that fibrin glue might be best for reducing CPIP and recurrence. However, a large-scale RCT is warranted to confirm the results.
