A Data-Driven Approach to Inguinal Hernia Repairs in Infants and Children

Area of Science:

• Pediatric Surgery
• Minimally Invasive Surgery
• Hernia Repair Outcomes

Background:

• Laparoscopic inguinal hernia repair is increasingly common in pediatric patients.
• The technique allows for contralateral processus vaginalis assessment, potentially reducing metachronous contralateral hernias.
• Metachronous contralateral hernias are most prevalent in the youngest pediatric populations.

Purpose of the Study:

• To investigate the hypothesis that primary laparoscopic repair is associated with lower rates of subsequent hernia repair in the youngest patients.
• To compare the rates of subsequent hernia repair between laparoscopic and open inguinal hernia repair techniques in children.
• To evaluate the long-term effectiveness of different surgical approaches for pediatric inguinal hernias.

Main Methods:

• A retrospective analysis of the Pediatric Health Information System database.
• Inclusion of patients aged 0-15 years who underwent inguinal hernia repair between 2016 and 2022.
• Exclusion of patients with only recurrent hernia codes or mixed laparoscopic/open procedure codes.

Main Results:

• Out of 109,456 patients, 18.58% had laparoscopic repair, and 2.32% required a second repair.
• Infants 6 months and younger undergoing unilateral laparoscopic repair had lower rates of subsequent surgery (OR 0.82).
• Open bilateral repair was associated with fewer subsequent repairs across all age groups (OR 1.93).

Conclusions:

• Unilateral laparoscopic inguinal hernia repair reduces the need for subsequent surgery in infants under six months.
• No significant difference in subsequent repair rates was observed for older pediatric patients undergoing unilateral laparoscopic repair.
• Open repair of bilateral hernias appears more durable, decreasing the likelihood of repeat operations in all age groups.
