Abstract:

Objective To investigate the clinical effect of precise preservation of left colonic artery in laparoscopic surgery in elderly patients with rectal cancer. Method 68 elderly patients with rectal cancer treated in Wuxi traditional Chinese medicine hospital from May 2017 to August 2021 were selected as the research object. According to different operation methods, they were divided into 30 cases in the control group (without retaining the left colonic artery during operation) and 38 cases in the experimental group (retaining the left colonic artery during operation). The operation indexes and postoperative recovery of the two groups were compared. Result There was no significant difference in intraoperative bleeding (P=0.774), total number of lymph nodes

cleaned (P=0.642), number of lymph nodes cleaned (P=0.571) and anastomotic bleeding (P=0.865) between the experimental group and the control group (P ＞ 0.05), but the operation time of the experimental group was longer (P=0.003), the postoperative hospital stay and anal ventilation time were shorter than those of the control group (P=0.006 and 0.001 respectively), and the incidence of anastomotic leakage was also lower than that of the control group (P=0.046). Conclusion For elderly patients with rectal cancer, preserving the left colonic artery during laparoscopic radical resection has no negative impact on the efficiency of lymph node dissection, and the risk of bleeding has not increased. At the same time, it can effectively shorten the postoperative exhaust time and reduce the incidence of anastomotic leakage.
