Abstract:
Objective
To compare the clinical efficacy of robotic and laparoscopic surgery for radical resection of sigmoid carcinoma.
Methods
A retrospective cohort study and propensity score assignment (PSM) were used to analyze the surgical efficacy of patients undergoing radical resection for sigmoid carcinoma in China-Japan Friendship Hospital of Jilin University from June 2019 to June 2024.The patients were divided into laparoscopic group and robotic group according to the inclusion criteria and the final surgical method selected. Among the 167 patients in the robotic group,and 334 patients in the laparoscopic group,PSM was used to match the basic data information related to age,gender,BMI,preoperative underlying diseases,preoperative ASA grade,tumor distance from anal margin,and TNM stage by 1:2,and the caliper value was 0.1. There were 112 patients in the post-PSM robot group and 224 patients in the laparoscopic group. There was no statistical significance in the comparison of baseline data between the two groups,and the differences in intraoperative and postoperative related conditions,complications,and pathological gains were studied between the two groups.
Results
The number of lymph node dissection in the robot group was significantly higher than that in the laparoscopic group (Z=-4.389,P<0.001),and the amount of surgical bleeding was significantly lower than that in the laparoscopic group(Z=-4.948,P<0.001). The number of postoperative Clavien-Dindo grade II and above complications was significantly lower than that of the laparoscopic group (χ2=19.145,P<0.001),and the proportion of postoperative hospital stay in total hospital stay was significantly lower than that of the laparoscopic group(Z=-3.896,P<0.01).
Conclusion
Compared with laparoscopically assisted radical resection of sigmoid carcinoma,robot-assisted radical resection of sigmoid carcinoma is more accurate,less invasive and faster postoperative recovery.
