ABSTRACT: In most children, an inguinal hernia arises because the processus vaginalis remains open. Repair is therefore directed at closing the internal-ring communication, and mesh reinforcement is seldom required. Although the operation is routine, several decisions are still debated. In premature infants, the risk of incarceration must be weighed against anesthetic and respiratory risk. An open contralateral processus vaginalis may remain asymptomatic, and laparoscopic operations vary enough that their complications should not be considered as a single group. Both open herniotomy and laparoscopic repair usually have low recurrence rates, but available comparisons are too imprecise to exclude meaningful differences in rare injuries and late outcomes. Intracorporeal suturing and percutaneous extraperitoneal closure also have different failure patterns, including incomplete capture of the ring, loss of knot security, and access injury. Recent randomized data favor postponing repair in carefully selected stable premature infants whose hernia is reducible and whose caregivers have reliable follow-up and prompt access to pediatric surgical care. A similarly selective policy is appropriate for the opposite groin. With a pooled metachronous hernia risk of about 6%, approximately 17 prophylactic procedures would be required to prevent one later hernia if every closure were effective. A recent infant trial reported a number needed to treat of 24 to prevent one reoperation during the first year. A dependable number needed to harm is unavailable because complications attributable to treatment of the second side are uncommon and poorly reported. This review considers how age, clinical presentation, operative method, and family circumstances influence diagnosis, timing, choice of repair, contralateral management, and follow-up.
