Comparative Study On Laparoscopic Versus Open Surgery For Elderly Colorectal Cancer Patients

ObjectiveColorectal cancer is the common malignant digestive tumor, the morbidity showing an increasing tendency. The safety and oncologic adequacy of laparoscopic surgery for colorectal cancer remain controversial, while definitive long-term results are not clear. The aim of this study is to evaluate the feasibility and oncologic safety for elderly colorectal cancer patients with laparoscopic versus open surgery.Material and MethodsWe analyzed the outcomes of 106 patients who underwent laparoscopic(53 patients) or open(53 patients) radical resection between Jan 2012 and Apr 2014, from a prospectively maintained database of Sir Run Run Shaw Hospital. The patients we selected were all older than the age of 65. We collected the patients information including age, gender, year of surgery, American Society of Anesthesiology score, and body mass index, perioperative blood loss, post-operative bleeding, procedural time,cost and length of hospital stay. Also, postoperative recovery, postoperative mortality and morbidity were assessed. Using the contrastive analysis to figure out feasibility and oncologic safety for elderly colorectal cancer patients with laparoscopic versus open surgery.ResultsThe laparoscopic surgery group and open surgery group were similar for the basic characteristics(age, gender, tumor location, BMI, TNM stage, ASA grade). The mean operation time of open group is longer than the laparoscopic group (173.3±9.4 min VS 160.5±7.6min, p>0.05). The perioperative blood loss of open group is more than the laparoscopic group (169.9±12.2ml VS 100.1±9.8ml, p=0.005). The open group requires more time than the laparoscopic group for food intake time (4.7±0.21d VS 3.2±0.29d, p=0.02). Postoperative complications, hospitalization cost, and length of hospital stay had no difference, p>0.05.ConclusionThe data we dealing with, indicate that laparoscopic surgery for colorectal cancer is better than open surgery because of perioperative blood loss and the intestinal function recovery. So the elderly patients who got colorectal cancer can choose laparoscopic surgery. It is safe.
