Using local rather than general anesthesia for inguinal hernia repair is associated with shorter operative time and enhanced postoperative recovery

Abstract

BackgroundInguinal hernia repair is the most common general surgery procedure and can be performed under local or general anesthesia. We hypothesized that using local rather than general anesthesia would improve outcomes, especially for older adults. MethodsThis is a retrospective review of 97,437 patients in the Veterans Affairs Surgical Quality Improvement Program who had open inguinal hernia surgery under local or general anesthesia. Outcomes included 30-day postoperative complications, operative time, and recovery time. ResultsOur cohort included 22,333 (23%) Veterans who received local and 75,104 (77%) who received general anesthesia. Mean age was 62 years. Local anesthesia was associated with a 37% decrease in the odds of postoperative complications (95% CI 0.54–0.73), a 13% decrease in operative time (95% CI 17.5–7.5), and a 27% shorter recovery room stay (95% CI 27.5–25.5), regardless of age. ConclusionsUsing local rather than general anesthesia is associated with a profound decrease in complications (equivalent to “de-aging” patients by 30 years) and could significantly reduce costs for this common procedure.
