Laparoscopic gastrectomy for gastric cancer in the elderly patients

This study aimed to investigate the short-term surgical outcomes of laparoscopic gastrectomy for gastric cancer in elderly patients in order to determine the safety, feasibility, and risk factors for postoperative complications associated with this procedure. We retrospectively investigated 208 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2007 and September 2014. After excluding 15 patients with unusual medical histories or surgical treatments, 193 were selected for this cohort study. We divided the patients into two cohorts: elderly patients (a parts per thousand yen75 years old) and non-elderly patients (< 74 years old). We compared these cohorts with respect to clinicopathological characteristics and intraoperative and postoperative parameters. The overall complication rates were 11.4 % (8 of 70 patients) in the elderly cohort and 8.1 % (10 of 123 patients) in the non-elderly cohort (P = 0.449). In a univariate analysis, Charlson comorbidity index (CCI) of a parts per thousand yen3, American Society of Anesthesiologists (ASA) score of 3, operative time of a parts per thousand yen330 min, and intraoperative blood loss of a parts per thousand yen50 ml were found to correlate significantly with postoperative complications. In a multivariate analysis, CCI of a parts per thousand yen3 (P = 0.034), ASA score of 3 (P = 0.019), and intraoperative blood loss of a parts per thousand yen50 ml (P = 0.016) were found to be independent risk factors of postoperative complications. In contrast, age was not found to significantly affect the risk of postoperative complications. Laparoscopic gastrectomy for gastric cancer can be successfully performed in elderly patients with an acceptable complication rate. This study suggested that high CCI, ASA score, and intraoperative blood loss volume were identified as independent predictors of postoperative complications after laparoscopic gastrectomy for gastric cancer.
