[Efficacy of Laparoscopic Surgery for Elderly Patients with Colorectal Cancer Over 80 Years Old]

The efficacy of laparoscopic surgery for elderly patients aged over 80 years who have colorectal cancer was investigated concerning complications. Sixty-five patients over 80 years old who underwent colorectal cancer resection until January 2018 were enrolled. Factors that led to complication were analyzed retrospectively. Thirty-three men and 32 women were included, with a median age of 83 years. Forty-eight cases were located at the colon; and 17, at the rectum. The median operating time was 164 minutes, including 39 cases treated with the laparoscopic approach. Postoperative complications were observed in 28 cases(43.1%), of which 15(23.1%)had a Clavien-Dindo(CD)classification of Grade BⅡ. These cases had significantly prolonged postoperative hospital stay. Complications included 10 cases of incisional surgical site infection(SSI), 9 cases of ileus, 6 cases of melena, 2 cases of urinary infection, 2 cases of urinary disorder, and 1 case of postoperative death. Open surgery was the only significant factor associated with the incidence of CD classification of BⅡ(p=0.0330). Among the complications, the incisional SSI was reduced by laparoscopic surgery(p=0.0050). The number of laparoscopic surgeries reduced the incidence of CD classification BⅡ of complications in elderly patients aged over 80 years who had with colorectal cancer resection. The use of incisional SSI also decreased with the use of laparoscopic surgery. Laparoscopic surgery for colorectal cancer in elderly patients may lead to reduced complication rates.
