Abstract: Aim: In countries with longer life expectancies, the nonagenarian population is increasing. Therefore, there is greater demand for healthcare, including surgical procedures. The aim of the present study was to determine the outcomes of surgery carried out on nonagenarians in terms of long-term survival after the procedure. Methods: We carried out a cross-longitudinal study on a cohort of 159 nonagenarian patients, who underwent a non-cardiac, non-traumatic surgical procedure in our institution between January 1999 and December 2011. The following variables were recorded: sociodemographic characteristics, American Society of Anesthesiologists score, Charlson Comorbidity Index, surgical site, postoperative complications, operative mortality and long-term survival. The output variable was long-term survival. Results: Of the 159 patients,99 women (62%) and 60 men (38%), with a mean age of 91.8 years (SD ± 2.0 years), 44 cases were operations for malignant disorders (28%), 117 cases (74%) under emergency conditions and 42 cases (26%) were elective treatments. The operative mortality was 29%, 4.8% for elective surgery and 37.6% for emergency surgery (P < 0.001). The postoperative complication rate, including death, was 60%. The probability of survival at 1, 3, and 5 years was 59.6%, 35.8% and 24.1%, respectively. In multivariate analysis, American Society of Anesthesiologists score (HR 2.07, 95% CI 1.58–2.72), emergency surgery (HR 1.64, 95% CI 1.05–2.57) and postoperative medical complications (HR 2.58, 95% CI 1.73–3.85) were independently related to 5-year survival. Conclusions: These findings support the perioperative safety of elective general surgery in nonagenarian patients. In selected nonagenarian patients with no cognitive impairment, surgery must not be denied. These data might be useful for surgical decision-making or informed consent for nonagerians.
