Abstract

Background: While elective inguinal hernia repair (IHR) in octogenarians carries a low 30-day mortality rate, long-term outcomes are uncharted. If on average, veteran octogenarians are expected to succumb to pre-existing cardiopulmonary disease within a year of diagnosis, watchful waiting might be advisable. This study interrogated long-term mortality and its predictors following elective IHR in veteran octogenarians. Materials and methods: This is a retrospective analysis of 109 veterans (≥ 80 years of age), ten of which were nonagenarians who had an elective IHR. Data were dichotomized between deceased vs. non-deceased patients for univariable and multivariable analyses. Patient characteristics were also assessed in patients undergoing general (GA) vs. local (LA) anesthesia and corrected for unilateral repair and age. Kaplan–Meier curves were generated in corrected and uncorrected cohorts receiving GA vs. LA. Results: At the time of analysis, 46 (45.0%) octogenarians were deceased. The average time to death following IHR was 3.7 ± 2.9 years [range (37 days–12.4 years)]. Univariable analysis showed renal disease (19.9% vs. 5.3%), operative time (67.9 ± 29.0 vs. 56.1 ± 14.4 min) and use of GA (73.0% vs. 34.8%) associated with long-term mortality (all p < 0.01). Renal disease [odds ratio (95% confidence intervals) 4.1 (1.2–13.8)] and use of GA [5.0 (2.0–10.0)] were independent predictors of mortality. Patients undergoing LA (n = 62) were older, were more likely to have cardiac disease, and had a higher ASA compared to patients receiving GA (n = 47). After correcting for age, cardiac disease and higher ASA remained more common in patients submitting to LA. Long-term mortality was significantly higher in both matched and unmatched octogenarians undergoing GA. Conclusion: Octogenarian veterans with a high burden of comorbid conditions are unlikely to experience short-term mortality because of their pre-existing conditions. Inguinal hernia repair should be offered to octogenarian veterans, but GA should be avoided whenever possible.
