Abstract

Objective: We systematically reviewed the literature and pooled data for a meta-analysis to compare the efficacy and safety of mesh fixation and nonfixation in laparoscopic total extraperitoneal (TEP) hernia repair. Materials and Methods: We performed a systematic search of PubMed® and a Cochrane review for all randomized controlled trials that compared the efficacy and complications of mesh fixation versus nonfixation in TEP hernia repair. The evaluated outcomes included perioperative (operative time and conversion rate) and postoperative parameters (pain scores, duration of hospital stay, surgical complications including seroma, delayed return of bladder function, chronic pain, and recurrence). Cochrane Collaboration Review Manager Software (RevMan®, version 5.2.6) was used for statistical analysis. Results: Ten trials met the inclusion criteria and were included in a pooled analysis. In total, 1099 patients (1467 hernias) had received TEP hernia repair (748 and 719 hernia defects in the nonfixation and fixation groups, respectively). The nonfixation group required shorter operative time (weighted mean difference [WMD] = -2.36 min, P= 0.0006) and had less pain on postoperative day 1 (WMD = -0.44, P= 0.04) than the fixation group. No significant differences were observed between groups with regard to conversion rate, hospital stay, recurrence rate, or complication rate. However, the incidence of postoperative urine retention was higher in the fixation group (odds ratio = 0.26, P= 0.03). Conclusion: For patients with a nonrecurrent uncomplicated hernia defect with the size <3 cm, nonfixation yielded comparable efficacy with mesh fixation, but less short-term postoperative pain, and a lower risk of urine retention. In addition, the nonfixation method involved a shorter operative time and lower costs. However, no difference in the incidence of chronic pain was observed.
