Purpose:
Shouldice Repair for inguinal hernias results in a low recurrence rate; however, little is known about the risk factors for these relapses. In the present study, we reviewed all patient's undergoing a reoperation for recurrence after a primary Shouldice Repair.
Methods:
Patients undergoing recurrent inguinal hernia repair from 2013 to 2017 were identified. The subgroup of patients with the first recurrence after a Shouldice Repair at this institution was selected and included. Data collection from the index and the reoperation surgery were performed, as well as statistical analysis.
Results:
A total of 125 patients were included in the analysis. The mean age was 50.8 ± 13.9 (body mass index: 24.6 ± 2.6 kg/m2), 97% were male. The most common interval for a recurrence reoperation was in the first 5 years following the initial surgery (37.6% of patients; mode: 1 year; median: 7 years; mean: 13.7 ± 13.8 years). A temporal median pattern for recurrence reoperation according to age interval was noted (patients < 41 years old: 20 years; patients aged 41-60 years old: 10 years and patients > 61 years: 2 years)).
Conclusion:
Patients undergoing reoperations for recurrent inguinal hernias after a primary Shouldice Repair presented a pattern of temporal recurrence according to age. Older patients present with earlier recurrences than younger ones, an important consideration in the assessment of patients postoperatively.
