High ligation in adolescents: Is it enough?

Background In adults, the gold standard for surgical repair of an inguinal hernia is a mesh repair, whereas, in children, the standard is high ligation of the hernia sac. However, adolescents represent a “gray zone” between children and adults, and there is no consensus on the most appropriate operation for inguinal hernias in these patients. We aimed to describe the outcomes in adolescents undergoing high ligation for inguinal hernia repair and determine what factors may portend an increased risk of recurrence in this population. Methods A retrospective cohort study was performed of all children that underwent open high ligation for an inguinal hernia at our tertiary children's hospital from January 2000 to January 2018, who were 12 to 18 years old at the time of surgery. We compared the patient demographic data, medical history, and repair characteristics for the cohort of hernias that developed a recurrence to the cohort that did not. Results During our study period, 256 adolescent patients underwent repair with 11 of those patients having both sides repaired for a total of 267 hernias repaired. The median age at surgery was 14.7 years, and 83.9% of the hernias were in male patients. There was a 6.0% recurrence rate, and all patients that developed recurrence underwent a reoperation. The median time from surgery to reoperation for recurrence was 3.1 years. Patients with recurrence were more likely to have cardiac (25.0% vs. 5.8%, p = 0.02) and gastrointestinal comorbidities (25% vs. 7.1%, p = 0.01). There were no other significant differences between the two cohorts. Conclusion High ligation of the hernia sac in adolescents is effective and has an acceptable risk of recurrence while avoiding any additional morbidity that may come from the use of mesh. Patients with cardiac and gastrointestinal comorbidities should be counseled on the higher risk of recurrence.
