Impact of age on groin hernia profiles observed during laparoscopic transabdominal preperitoneal hernia repair.

BACKGROUND: How increasing age affects the characteristics of groin hernia remains uncertain. This study evaluated the association between age and the type of groin hernia, especially with respect to its multiplicity, observed during laparoscopic transabdominal preperitoneal (TAPP) hernia repair. METHODS: We retrospectively evaluated 634 consecutive patients with primary groin hernia who underwent laparoscopic TAPP repair between October 2000 and June 2017. Patients were stratified into 4 age groups: < 60 years, 60-69 years, 70-79 years, and 80 years or older. RESULTS: The incidence of occult contralateral hernia and multiple ipsilateral hernias increased significantly with each increasing age group: 7.3%, 10.4%, 12.7%, and 20.8% for occult contralateral hernia (p = 0.005), and 5.6%, 9.2%, 16.8%, and 21.7% for multiple ipsilateral hernias (p < 0.001), respectively. Univariate analyses showed that an older age (age ≥ 70 years) was the only factor significantly associated with the presence of multiple groin hernias (odds ratio, 2.69; 95% confidence interval, 1.89-3.81; p < 0.001). In patients with multiple ipsilateral hernias, the prevalent form in men was a pantaloons hernia, with an incidence of about 70% across all age groups, whereas in women it was groin hernias, with one component being a femoral hernia, an obturator hernia, or both. CONCLUSIONS: The multiple occurrence of groin hernias, either unilaterally or bilaterally, was a clinical feature in the elderly.
