Abstract:
Objective:To investigate the clinical effects and advantages of laparoscopic total mesorectal excision in the treatment of colorectal cancer.Methods:A total of 82 patients with colorectal cancer who received treatment at the Second Affiliated Hospital of Guizhou Medical University from January 2020 to January 2023 were selected for a prospective study. They were randomly assigned to two groups using a random number table, with 41 cases in each group. The control group underwent conventional laparotomy, while the observation group received laparoscopic total mesorectal excision. Clinical efficacy, clinical indicators, and immune function indicators were compared between the two groups.Results:The operation time for patients in the observation group was (1.98 ± 0.31) hours, the length of hospital stay was (8.32 ± 2.38) days, the recovery time for bowel function was (2.15 ± 0.34) days, and the intraoperative blood loss was (112.35 ± 12.66) mL, all of which were shorter and lower than those in the control group [(2.46 ± 0.32) hours, (14.52 ± 2.42) days, (3.25 ± 0.15) days, and (167.78 ± 12.35) mL, t = 6.90, 11.70, 18.95, 20.07, all P < 0.001). The short-term response rate in the observation group was higher than that in the control group ( χ2 = 4.10, P < 0.05). The immune function indicators in the observation group, including the CD4 +/CD8 + ratio (1.78 ± 0.54), immunoglobulin A [(3.87 ± 0.73) g/L], and immunoglobulin G [(11.83 ± 2.88) g/L], were all better than those in the control group [(1.36 ± 0.53), (1.78 ± 0.63) g/L, (6.37 ± 2.45) g/L, t = 3.55, 13.88, 9.25, all P < 0.001]. The incidence of complications in the observation group was 2.44% (1/41), which was significantly lower than that in the control group [19.51% (8/41), χ2 = 4.49, P < 0.05]. Conclusions:Laparoscopic total mesorectal excision for patients with colorectal cancer has significant advantages, including faster recovery, less bleeding, and fewer complications, making it more superior to conventional laparotomy.
