Insights
Laparoscopic inguinal hernia repair in children reduces metachronous hernias but significantly increases recurrence rates compared to open repair. This study highlights a critical trade-off in pediatric surgical approaches.
Area of Science:
- Pediatric Surgery
- Surgical Outcomes
- Hernia Repair
Background:
- The optimal surgical technique for pediatric inguinal hernias remains a subject of ongoing debate.
- Assessing recurrence and metachronous hernia rates is crucial for evaluating different surgical approaches.
Purpose of the Study:
- To compare recurrence and metachronous hernia rates between open repair (OPEN) and laparoscopic repair (LAP) in pediatric patients.
- To analyze outcomes of pediatric inguinal hernia repair over a 5-year period.
Main Methods:
- A retrospective cohort study involving 1,952 pediatric patients (<14 years) undergoing inguinal hernia repair.
- Analysis of data from two children's hospitals over a 5-year period (2011-2015) with a minimum 4-year follow-up.
- Cox proportional regression was used to compare surgical approaches regarding recurrence and metachronous hernias.
Main Results:
- Laparoscopic repair (LAP) was associated with a lower incidence of metachronous contralateral hernias (1.4% vs. 3.8%, p=0.047).
- Open repair (OPEN) demonstrated a significantly lower recurrence rate (0.9% vs. 9%, p<0.001).
- Adjusted analysis revealed LAP had a substantially higher recurrence rate (Hazard Ratio 10.4).
Conclusions:
- Pediatric laparoscopic inguinal hernia repair offers a modest reduction in metachronous hernias.
- This benefit comes at the significant cost of a substantially increased hernia recurrence rate compared to open repair.
Purpose:
The optimal approach for pediatric inguinal hernia repair continues to be debated. We conducted a regional retrospective study to assess rates of recurrence and metachronous hernias after open repair (OPEN) and laparoscopic repair (LAP) METHODS: A retrospective cohort study was conducted at two children's hospitals that serve a region of approximately 4 million people. All patients < 14 years old undergoing OPEN or LAP by pediatric surgeons during a 5-year period (2011 - 2015) were analyzed after a minimum follow up of 4 years. Cox proportional regression was used to compare the effect of surgical approach on hernia recurrence and metachronous contralateral hernias.
Results:
A total of 1,952 patients, 587 female (30%) and 1365 male (70%), had 2305 hernias repaired. Median post operative follow up time was 6.6 years (range 4-9 years). OPEN and LAP were performed for 1827 (79%) and 478 (21%) hernias, respectively. There were no significant differences in rate of prematurity, age at repair, or frequency of emergent repair. LAP was associated with a lower incidence of metachronous contralateral hernias compared to OPEN (1.4% vs 3.8%, p = 0.047), and a higher incidence of recurrence (9% vs 0.9%, p < 0.001). After adjusting for confounders, LAP had a higher rate of recurrence than OPEN (hazard ratio 10.4, 95% CI 6-18.1).The recurrence rate did not decrease over the study period (p = 0.731).
Conclusion:
Laparoscopic inguinal hernia repair in children resulted in a modest decrease in the incidence of metachronous hernias, at the cost of a significant increase in recurrence.
Type Of Study:
Retrospective Comparative Study.
