1Medical College of Wisconsin, Milwaukee, USA.
Insights
Bilateral inguinal involvement is common in young children, peaking in the first year. Contralateral exploration for pediatric inguinal hernias is safe and beneficial, especially for those with a patent processus vaginalis.
Area of Science:
- Pediatric Surgery
- Surgical Outcomes
Background:
- Bilateral inguinal involvement is a concern in pediatric populations.
- The true incidence and implications of contralateral processus vaginalis require further elucidation.
Purpose of the Study:
- To determine the true incidence of bilateral inguinal involvement in preschool children.
- To evaluate the benefits and safety of contralateral exploration in pediatric inguinal hernia cases.
Main Methods:
- Retrospective and prospective studies were conducted.
- Anatomically based criteria were used to define positive inguinal exploration.
- Data were collected from a general pediatric population.
Main Results:
- Bilateral inguinal involvement was highest in the first year of life (68%) and decreased with age.
- Over 50% of children up to 6 years showed bilateral involvement.
- Contralateral exploration is safe, effective, and cost-effective.
Conclusions:
- Contralateral exploration is recommended for all preschool children undergoing inguinal hernia repair.
- This practice may offer lifelong benefits, particularly in cases of patent processus vaginalis.
- Contralateral exploration is a safe and cost-effective surgical strategy in pediatric inguinal hernia management.
Abstract:
Retrospective and prospective studies were undertaken to evaluate the true incidence of bilateral inguinal involvement in preschool children in an established general pediatric population. Unbiased, anatomically based criteria were established for a "positive" exploration. It was found that bilateral inguinal involvement was highest during the first year of life (68%) and decreased through the advancing years, to just above 50% at 6 years of age. Because a widely patent processus vaginalis may be a precursor of indirect inguinal hernia, contralateral exploration may carry lifelong benefits in those who have the processus vaginalis ligated. Based on the authors' observations, contralateral exploration can be offered to all preschool children, and in selected cases (difficult preoperative preparation, anesthetic high risk, strong family history, etc), even beyond this age. Contralateral exploration is a safe, effective, and cost-wise practice when performed in an appropriate setting.
