[Study of Laparoscopic Surgery for Elderly Patients with Colorectal Cancer]

The number of elderly patients and colorectal cancer patients is increasing, so laparoscopic surgery for colorectal cancer in elderly patients is suspected to increase. In 456 patients who underwent laparoscopic surgery for colorectal cancer, we investigated whether laparoscopic surgery for elderly patients with colon cancer patients could be performed equally compared to non-elderly patients. Preoperative ASA-PS was slightly poorer in elderly patients. There was no significant difference in pStage. The 5-year overall survival rate was lower in the elderly, but there were no significant differences in blood loss, operation time, postoperative hospital stays and incidence of complications of Clavien-Dindo classification grade 3 or higher. It was suggested that laparoscopic surgery for elderly patients with colorectal cancer may be safely performed compared with non-elderly patients.
