Introduction: The risk factors for postoperative complications after surgery for rectal cancer were compared between late elderly people and non-elderly people.
Materials and Methods: A total of 139 patients who underwent surgery for upper and lower rectal cancer at our department between January 1, 2008 and March 31, 2013 was investigated. These patients were divided into elderly (≥75 years old) and non-elderly (<75 years old) groups, and their clinicopathological factors, surgery-related factors, E-PASS, and PNI were compared.
Results: In the elderly group, 13 of 27 patients (48.1%) developed postoperative complications, and this proportion was significantly greater than in the non-elderly group (27.7%, p=0.0401). In elderly patients, univariate and multivariate analyses showed that E-PASS SSS (p=0.048) and elevated peripheral blood lymphocyte count (p=0.026) were independent risk factors for complications. In the non-elderly group, E-PASS SSS was the independent risk factor for complications (p=0.0398).
Conclusion: E-PASS SSS was found to be a useful index for assessing risks for postoperative complications in both the elderly and non-elderly groups. When performing surgery to treat rectal cancer in elderly people, paying careful attention to the preoperative peripheral blood lymphocyte count and minimizing surgical invasiveness may reduce the development of postoperative complications.
