Abstract:

Objective To compare the clinical efficacy of open and laparoscopic low anterior rectal resection in elderly patients with low rectal cancer. Method A total of 80 patients with low rectal cancer in the Airforce Hospital of Southern Theater Command from March 2020 to March 2022 were selected as the study subjects. Depending on the surgical method, they were divided into an observation group (laparoscopic low anterior rectal resection) and a control group (open low anterior rectal resection), with 40 patients in each group. Compare the surgical indicators, postoperative recovery, incidence of complications, and clinical efficacy between the two groups. Result There were statistically significant differences between the observation group and the control group in incision length [(6.13±0.94) cm vs. (15.82±1.54) cm], intraoperative bleeding volume [(56.14±10.35) ml vs. (118.33±12.74)

ml], and surgical time [(135.32 ± 30.64) min vs. (173.62±15.36)min]. However, there was no statistically significant difference in the number of lymph node dissection between the two groups [(13.64±2.31) vs.(13.78± 2.26), P=0.231]. There were statistically significant differences between the observation group and the control group in postoperative exhaust time [(1.86 ± 0.58)d vs. (3.72 ± 1.34)d], hospital stay time [(5.27 ± 1.18)d vs. (7.36 ± 2.47)d], and intestinal function recovery time [(1.86 ± 0.35)d vs. (2.83 ± 0.44)d]. The total incidence of complications in the observation group (2.50%) was significantly lower than that in the control group (25.00%) (P ＜ 0.05). All patients were followed up for 12 months. In the observation group, 1 case had local recurrence (2.5%), 2 cases had distant metastasis to the liver (5%), and there were no deaths; There was 1 local recurrence (2.5%) in the control group, with no distant metastasis or death, and there was no statistically significant difference between

the two groups (P ＞ 0.05). Conclusion Laparoscopic low anterior rectal resection for elderly rectal cancer patients has low trauma, low incidence of complications, and fast postoperative recovery.
