Background  The short-term outcomes of laparoscopic-assisted surgery for colorectal cancer (LAC) have not been fully evaluated in elderly patients. The aim of this study was to compare the short term surgical outcomes of LAC between the patients older than 75 years and those with non-elderly patients.    Methods  This retrospective multi-institutional study selected patients who underwent LAC between April 2013 and March 2014 at Yokohama City University Hospital and its related general hospitals. The patients were categorized into two groups: elderly patients (>75 years of age: group A) and non-elderly patients (<75 years of age: group B). Surgical outcomes and post operative complications were compared between the two groups.    Results  A total of 237 patients were evaluated in the present study. Eighty-four patients were classified into group A, and 153 into group B. Preoperative clinicopathological outcomes demonstrated no significant differences except for the ASA score. When comparing the surgical outcomes between group A and group B, the rate of conversion to open procedure (3.6% vs 5.2%,  P  = 0.750), median operation time (232 min vs 232 min,  P  = 0.320), median blood loss (20 ml vs 12 ml,  P  = 0.350). The differences were not significantly different in the surgical outcomes. The incidences of > grade 2 post operative surgical complications were similar between two groups ((19.0% vs 15.7%,  p  = 0.587). No mortality was observed in this study. The length of postoperative hospital stay was also similar (10 days vs 10 days,  p  = 0.350).    Conclusions  The present study suggested that LAC is safe and feasible, regardless of the age of the patient, especially for elderly patients who may be candidates for colon cancer surgery.
