Impact of age over 75 years on outcomes after pancreaticoduodenectomy.
Résumé
BACKGROUND: The risks associated with pancreaticoduodenectomy (PD) in elderly patients continue to be debated. The aim of our study was to assess the incidence of death and postoperative complications following PD and identify the risk factors in patients >75 y. STUDY DESIGN: All patients who underwent PD between January 2000 and September 2009 were analyzed retrospectively. Patients were divided into two groups according to age (Group 1: patients aged <75 y, and Group 2: patients aged ≥ 75 y). Morbidity and perioperative mortality risk factors were analyzed using univariate and multivariate analyses. RESULTS: Among the 314 patients, 273 were included in Group 1 (sex ratio 1.4) and 41 in Group 2 (sex ratio 1). In multivariate analysis, postoperative hemorrhage (PH) (OR 6.61, IC95% [1.96; 22.31], P = 0.002) and age >75 y proved to be predictive factors for mortality (OR 11.04, IC95% [2.57; 47.49], P = 0.001). When compared with Group 1, Group 2 was associated with increased postoperative deaths (24.4% versus 3.66%, P < 0.001) and pancreatic fistulas (26.8% versus 13.2%, P = 0.041), in particular, Grade C fistulas (14.6% versus 4.4%, P = 0.023). In multivariate analysis, only PH proved to be an independent predictive factor for mortality (OR 12.9, IC95% [1.07; 155.5], P = 0.04). CONCLUSIONS: PD in elderly patients aged over 75 y appears to be associated with an increased risk of postoperative death and pancreatic fistula. No single preoperative factor made it possible to predict this risk.
