| Background:Colorectal cancer is a common malignant tumor in the world.More than 1.93 million people are diagnosed with the disease every year in the world,accounting for 9.7% of all new cancer cases.The number of new cases of colorectal cancer in China is second only to lung cancer.Which has become the second leading cancer.At present,the treatment principle of colorectal cancer is a comprehensive treatment based on surgery.With the development of minimally invasive surgical techniques,the surgical methods have also developed from traditional open surgery to laparoscopic surgery and the most advanced robotic surgery.The most used robotic surgery system is the Da Vinci robot,whose surgical effect has been widely recognized at home and abroad,and has a better short-term effect than laparoscopic surgery.However,because of the higher cost of Da Vinci robotic surgery,it is difficult to be accepted by patients in my country.Arm reduction surgery is to reduce the use of a Da Vinci robot arm and replace it with an additional assistant to operate the instrument,so as to reduce the cost of surgery.Objective:To compare the clinical data of colorectal cancer patients who underwent conventional da Vinci robotic surgery and da Vinci robotic arm reduction surgery,to compare the short-term curative effects of these two surgical methods on colorectal cancer,and explore the clinical value of da Vinci robotic arm reduction surgery and provide clinical basis for its application.Methods:We retrospectively collected 98 patients with left-sided,right-sided colon cancer or low rectal cancer(tumors located below peritoneal reentry)who were admitted to the Department of Gastrointestinal Surgery of the Third Xiangya Hospital of Central South University from January 2021 to January 2022.The clinical data of patients undergoing radical resection,all operations were performed by the same surgical team,and were divided into a conventional group(using 3 robotic arms,n = 36)and a reduced arm group(using 2 robotic arms)according to the number of robotic arms used during the operation robotic arm,n = 62).The collected hospitalization data included: age,gender,surgical site,Body Mass Index(BMI),American Society of Anesthesiologists(ASA)classification,underlying diseases,history of abdominal surgery,operation time,surgery The amount of bleeding,the number of detected lymph nodes,T stage,N stage,tumor differentiation,clinical tumor stage,time of first removal of urinary catheter after operation,time of first fluid intake after operation,time of first exhaust after operation,length of postoperative hospital stay,Postoperative complications,robot consumables costs,total hospitalization costs,etc.SPSS 25.0 software was used to statistically analyze the differences in clinical data and recent clinical efficacy between the two groups.Results:There was no significant difference in preoperative general data between the conventional group and the reduced arm group,indicating that there was comparability between the two groups.The operations in both groups were successfully completed,and there was no intraoperative conversion to laparotomy,no serious intraoperative complications and no intraoperative deaths.There were no significant differences between the two groups in terms of operation,postoperative pathological results,postoperative recovery,and postoperative complications(all P>0.05),indicating that there was no difference in the short-term efficacy of surgery between the two groups.There was a statistically significant difference in the cost of surgery between the two groups(P<0.05),and the cost of the arm reduction group was significantly lower.Conclusion:Compared with conventional da Vinci robotic surgery,there is no significant difference in the short-term curative effect of da Vinci robotic arm reduction surgery for colon cancer and low rectal cancer.Odd robot arm reduction surgery can reduce medical expenses without affecting the surgical effect,and it is worthy of further development. |
