Introduction:
There is uncertainty regarding the method of mesh fixation and peritoneal closure during transabdominal preperitoneal (TAPP) repair for inguinal hernias, with no definitive guidelines to guide surgeon choice.
Methods:
MEDLINE, Cochrane, Central Register of Clinical Trials, and Web of Science were searched for RCTs published until November 2023. Risk ratios (RRs) and mean differences (MD) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p values inferior to 0.10 and I2 > 25% considered significant. Statistical analyses were conducted using Review Manager version 5.4 and RStudio version 4.1.2 (R Foundation for Statistical Computing).
Results:
Eight randomized controlled trials (RCTs) were included, comprising 624 patients, of whom 309 (49.5%) patients were submitted to TAPP with the use of tacks, and 315 (50.5%) received suture fixation. The use of tacker fixation was associated with a significant increase in postoperative pain at 24 h (MD 0.79 [VAS score]; 95% CI 0.38 to 1.19; p < 0.0002; I2 = 87%) and one week (MD 0.42 [VAS score]; 95% CI 0.05 to 0.79; p < 0.03, I2 = 84%). The use of tacks was associated with shorter operative time (MD-25.80 [min]; 95% - 34.31- - 17.28; P < 0.00001; I2 = 94%). No significant differences were found in overall complications, chronic pain, seromas, hematomas, and urinary retention rates.
Conclusion:
In patients who underwent TAPP hernia repair, tacks are associated with decreased operative time but increased postoperative pain at 24 h and one week.
