Insights
Laparoscopic inguinal hernia repair (LIHR) and laparoscopically assisted inguinal hernia repair (LAIHR) in children show similar safety and efficacy. Both minimally invasive techniques offer low recurrence and complication rates, with LAIHR potentially offering better cosmetic outcomes.
Area of Science:
- Pediatric Surgery
- Minimally Invasive Surgery
- Surgical Outcomes Research
Background:
- Inguinal hernia repair is a common pediatric surgical procedure.
- Minimally invasive techniques like LIHR and LAIHR are widely used but their comparative effectiveness requires further investigation.
Purpose of the Study:
- To systematically review and meta-analyze randomized controlled trials comparing LIHR and LAIHR in pediatric patients.
- To evaluate the efficacy, safety, and complication profiles of both surgical approaches.
Main Methods:
- Systematic literature search of PubMed, Embase, Scopus, Web of Science, and CENTRAL up to March 2025.
- Inclusion of 16 randomized controlled trials involving 1,402 pediatric patients.
- Meta-analysis using random-effects models to compare hernia recurrence, operative duration, transient hydrocele, wound complications, and recovery outcomes.
Main Results:
- No significant differences in hernia recurrence rates (LIHR: 1.9%, LAIHR: 0.7%) or rates of transient hydrocele and wound infection.
- Extreme heterogeneity in operative time (I² = 100%) precluded meaningful pooled comparison, indicating technique and center-specific variability.
- Both LIHR and LAIHR demonstrated excellent safety profiles and low complication rates, with some studies suggesting better early recovery and cosmetic satisfaction with LAIHR.
Conclusions:
- LIHR and LAIHR are both safe and effective for pediatric inguinal hernia repair, with comparable recurrence and complication rates.
- Operative time is not a distinguishing factor between the techniques but is highly context-dependent.
- LAIHR may offer advantages in specific scenarios regarding surgical time and aesthetic results, with the choice of technique dependent on patient needs, surgeon expertise, and institutional resources.
Abstract:
Among children, surgical procedures most often done include inguinal hernia repair. Although both laparoscopically assisted inguinal hernia repair (LAIHR) and laparoscopic inguinal hernia repair (LIHR) are rather common minimally invasive methods, their relative safety, efficacy, and outcomes are still questionable. This systematic review and meta-analysis sought to examine the efficacy and complication profiles of LIHR and LAIHR in children derived from data from randomized controlled trials. Through March 2025, PubMed, Embase, Scopus, Web of Science, and CENTRAL were searched systematically to find randomized controlled trials comparing LIHR and LAIHR in pediatric patients. Included were studies reporting on hernia recurrence, operative duration, transient hydrocele, wound complications, and recovery outcomes. Random-effects models were used to conduct meta-analyses. Using the American Society of Plastic Surgeons (ASPS) grading scheme for prognostic or risk studies, the degree of evidence and strength of suggestions were evaluated. Sixteen trials with a total of 1,402 pediatric patients were included. Pooled findings showed no statistically significant variation in hernia recurrence rates between LIHR (1.9%; 95% CI: 0-3%) and LAIHR (0.7%; 95% CI: 0-2%) (P = 0.052; I² = 29%). Likewise, no statistically significant differences were found in the rates of transient hydrocele (P = 0.1379) or wound infection (P = 0.4951). Analysis of operative time revealed extreme statistical heterogeneity (I² = 100%), precluding a meaningful pooled comparison. This indicates that operative duration is highly variable and dependent on unmeasured, center-specific factors such as surgical technique and experience, rather than representing a consistent difference between the two broad procedure categories. Both strategies showed outstanding safety profiles and low complication rates. Early recovery results and cosmetic satisfaction were somewhat more positive with LAIHR in some studies. Both LIHR and LAIHR are effective, safe, and cosmetically acceptable ways to repair pediatric inguinal hernia, with no major variances in recurrence or most complication rates. Operative time is not a distinguishing feature between the techniques but is instead highly context-dependent. LAIHR may have benefits in chosen contexts for surgical time and aesthetic results. The method chosen should fit patient's needs, surgical proficiency, and hospital's assets.
