Insights
Pediatric laparoscopic inguinal hernia repair offers similar low reoperation rates and complication risks compared to open surgery. Laparoscopic visualization of the contralateral side significantly reduces the need for future contralateral repairs.
Area of Science:
- Pediatric Surgery
- Minimally Invasive Surgery
- Hernia Repair
Background:
- Pediatric laparoscopic inguinal hernia repair is not widely accepted.
- Comparison between open and laparoscopic techniques is crucial for surgical decision-making.
Purpose of the Study:
- To compare the outcomes of open versus laparoscopic inguinal hernia repair in children.
- To evaluate ipsilateral reoperation rates, contralateral repair rates, operative time, and complications.
Main Methods:
- Retrospective cohort study of 1697 children (0-14 years) undergoing inguinal hernia repair from 2010-2016.
- Classification into five groups: open unilateral without exploration, open unilateral with contralateral exploration, open bilateral, laparoscopic unilateral, and laparoscopic bilateral repair.
- Outcomes assessed included ipsilateral reoperation, metachronous contralateral repair, incision time, and complications.
Main Results:
- Laparoscopic and open approaches showed similar low ipsilateral reoperation rates (0.3% vs 0.8%) and comparable complication rates (1.11% vs 0.43%).
- Metachronous contralateral repair rates were significantly lower in patients undergoing laparoscopic unilateral repair (0.9%) or open repair with contralateral exploration (0.7%) compared to open unilateral repair without exploration (3.8%).
Conclusions:
- Both laparoscopic and open inguinal hernia repair techniques are safe and effective in children.
- Laparoscopic contralateral exploration during unilateral inguinal hernia repair significantly reduces the incidence of metachronous contralateral repair, making it a valuable approach.
Background:
Pediatric laparoscopic inguinal hernia repair is not widely accepted.
Study Design:
Children 0-14 years who underwent inguinal hernia repair during 2010-2016 at Kaiser Permanente Northern California were classified into five groups: (1) open unilateral repair without contralateral exploration; (2) open unilateral repair with contralateral laparoscopic exploration ("open+explore"); (3) open bilateral repair; (4) laparoscopic unilateral repair; and (5) laparoscopic bilateral repair. Outcomes included ipsilateral reoperation, metachronous contralateral repair, incision time, and complications.
Results:
The study included 1697 children. Follow-up averaged 3.6 years after open (N = 1156) and 2.6 years after laparoscopic (N = 541) surgery. Metachronous contralateral repair was performed in 3.8% (26/683) of patients with open unilateral surgery without contralateral exploration, 0.7% (2/275) of open+explore patients, and 0.9% (3/336) of laparoscopic unilateral patients (p < 0.01). Ipsilateral repair was performed in 0.8% (10/1156) of open repairs and 0.3% (2/541) of laparoscopic repairs. Chart review confirmed 5 postoperative infections in 1156 patients with open surgery (0.43%) and 6 infections in 541 patients with laparoscopic surgery (1.11%) (p = 0.11).
Conclusion:
Our study's laparoscopic and open approaches have similar low ipsilateral reoperation rates, incision times, and complications. The use of laparoscopy to visualize the contralateral side resulted in a significantly lower rate of metachronous contralateral repair.
