Abstract

Objective: This systematic review and meta-analysis investigated the feasibility and ef-fectiveness of laparoscopic hernia repair with the extraperitoneal approach in pediatric inguinal hernias. Summary Background Data: Inguinal hernia repair is the most common operation in pediatric surgical practice. Although open hernia repair (OHR) is a well-established procedure with good outcomes, studies have reported acceptable or even better outcomes of laparoscopic hernia repair with the extraperitoneal approach (LHRE). However, a meta-analysis comparing LHRE with OHR is lacking. Methods: PubMed, EMBASE, and Cochrane Library databases were searched for randomized controlled trials (RCTs) and comparative studies (prospective or retrospective). Outcomes were metachronous contralateral inguinal hernia (MCIH), hernia recurrence, surgical site infection, operation time, and hospitalization length. A meta-analysis was performed, and risk ratios (RR), weighted mean difference (WMD), and 95% confidence intervals (CI) were calculated using random-effects models. Results: Five RCTs and 21 comparative studies involving 24,479 patients were included. Lower MCIH incidence (RR: 0.11, 95% CI: 0.07 to 0.17; p < 0.00001) and a trend of shorter operation time (WMD: −11.90 min, 95% CI: −16.63 to −7.44; p < 0.00001) were found in the LHRE group. No significant differences in ipsilateral recurrence hernias, surgical site infection, and length of hospitalization were found between the groups. Conclusions: LHRE presented lower MCIH incidence and shorter operation times, with no increase in hernia recurrence, surgical site infection, or length of hospitalization. As more surgeons are increasingly becoming familiar with LHRE, LHRE would be a feasible and effective choice for pediatric inguinal hernia repair.
