Comparison Of Short-term Efficacy Between Robotic And Laparoscopic Radical Gastrectomy For Gastric Cancer Patients With Different Body Mass Indices

Objective:To parallel the recent curative effect of robotic radical gastrectomy and laparoscopic radical gastrectomy for gastric cancer in patients with different BMI(Body Mass Index),and to explore the possibility of BMI becoming a reference for both doctors and patients in choosing surgical operating systems before surgery.Method:Retrace analysis of the clinical and pathological data of 443 gastric cancer patients who underwent surgical treatment receive and cure in the Seventh Ward of the First Affiliated Hospital of Nanchang University from January 2021 to June 2022.Divide patients into three groups based on their BMI values: 68 cases in the weight loss group(BMI ≤ 18.5kg/m 2)、 238 cases in the normal group(18.5kg/m 2 <BMI≤23.9kg/m 2)、137 cases of super recombination(BMI>23.9kg/m 2)。Compare the preoperative baseline data,intraoperative relevant indicators,short-term postoperative efficacy,and pathological data of different BMI groups undergoing robotic gastric cancer radical surgery and laparoscopic gastric cancer radical surgery.Result:There was no statistically significant difference in baseline data between the laparoscopic radical gastrectomy group and the robotic radical gastrectomy group among the three groups of patients(P>0.05).In the weight loss group,compared to laparoscopy,the robot group had a shorter postoperative feeding time [3(2,3)vs 3(3,4)days,(P<0.05)].In the normal group,compared with the laparoscopic group,the robot group significantly shortened the total surgical time [172(144,205)vs 215(175,259)minutes,(P<0.05)],separation time [88.5(70,110)vs 117(93,150)minutes,(P<0.05)],reconstruction time [44(31,60)vs 60(43,81)minutes,(P<0.05)],and food retention time [3(3,4)vs 3(3,5)days,(P<0.05)] The time for removing the drainage tube [6(6,8)vs 7(6,8)days,(P<0.05)],and the postoperative hospital stay[8(7,10)vs 7(7,9)days,(P<0.05)].In the obesity group,the robot group shortened the total surgical time [190(170,237)vs 240(192,297)minutes,(P<0.05)],separation time [97(85,118)vs 130(103,170)minutes,(P<0.05)],and reconstruction time [44(32,65)vs 63(50,90)minutes,(P<0.05)];The extraction time of the drainage tube is shorter [6(6,7)vs 6(5,6)days,(P<0.05)],and the postoperative hospital stay is shorter [7(7,8)vs 7(6,7)days,(P<0.05)].At the same time,it can clean more gastric lymph nodes [14.3 ± 10.6 vs 10.6 ± 6.9,(P<0.05)].For all patients,the total cost of the robot group is about 13000 yuan higher than that of the laparoscopic group.There was no statistically significant difference in the frequency of recent postoperative complications between Them.Conclusion:The robot operating system can bring more short-term benefits to gastric cancer patients with high BMI values,and BMI values should be considered as an indicator for both doctors and patients when preparing for gastric cancer radical surgery.
