Abstract

Background Laparoscopic hernia repair (LH) is reported to have superior outcomes in pediatric inguinal hernia repair, but its advantages in incarcerated inguinal hernia (IIH) are not defined. We compare the outcomes of LH versus open hernia repair (OH) for pediatric IIH.

Methods We performed a systematic review on all published analyses of LH versus OH for IIH. We identified studies published in 2000 to 2018 from Medline, PubMed, Embase, Google Scholar, and Cochrane databases. We included only studies that compared both surgical techniques on children aged 18 years or younger. Search terms were variations of “incarcerated inguinal hernia,” “hernia repair,” “laparoscopy,” and “child.” We categorized complications as major (testicular atrophy, ascending testis, recurrence, iatrogenic visceral injury) and minor (wound infection). Heterogeneity was assessed using I2; meta-analyses were performed using random- or fixed-effects models as appropriate. Weighted mean differences (WMDs) or odds ratios (ORs), with their corresponding 95% confidence intervals (CIs), were used for analysis of continuous and dichotomous variables, respectively. Significance level was at p-value less than 0.05.

Results Our initial search yielded 549 unique citations. Eight retrospective cohort (RC) studies (584 patients) were included in the final analysis (339 LH, 245 OH). Overall, major complications (eight RC; n = 584; OR = 0.38; 95% CI: 0.17–0.88; p = 0.02) were more common in OH. When each complication was assessed individually, there were no differences between groups. The length of hospital stay in the LH group was shorter than in the OH group (five RC; n = 418; WMD = − 1.39; 95% CI, −2.56 to −0.22; p = 0.02).

Conclusion Laparoscopic repair for IIH is associated with less major complications and shorter hospital stay, but data are limited due to the absence of randomized controlled trials.
