A Comparative Study Of Radical Resection Of Rectal Cancer Between Robotic-assisted And Laparoscopic

ObjectiveTo compare the safety and short-term efficacy of robotic-assisted versus laparoscopic for radical resection of rectal cancer.MethodsAccording to the order of continuous selection in October 2014 to September 2016,at the First Affiliated Hospital of Zhengzhou University,anorectal surgery rectal cancer radical surgery patients.Among them,Da Vinci robot completed 69 cases of surgery,laparoscopic surgery was 61 cases.There were no significant differences in gender,age,location of rectal cancer,tumor diameter and duration of staging(P> 0.05)between the two groups.The operative time,intraoperative blood loss,postoperative exhaust time,catheter extraction time,distance of tumor distance,length of hospital stay and clinical efficacy were compared between the two groups.ResultsThe surgery of the two groups were successfully completed,intraoperative without laparotomy.The operative time of the robotic group and laparoscopic group was(257.49 ± 86.25 min vs 214.49 ± 75.76 min,P = 0.006).The mean time of operation was(284.14 ± 98.80)min in the first 35 cases and(230.05 ± 61.17)min in the 34 cases,and the difference was statistically significant(P = 0.022),With the accumulation of experience the operation time in robot surgery was reduce;The intraoperative blood loss was less than that in the laparoscopic group(96.52 ± 56.59 ml vs 135.74 ± 58.81 ml,P<0.05);The first exhaust time was earlier than that in the laparoscopic group(3.65 ± 1.15 d vs 4.28 ± 1.19 d,P<0.05);Urinary catheterization was earlier than that of laparoscopic group(6.01 ± 1.10 d vs 7.26 ± 1.62 d,P<0.05);and the distance from the lower edge of the tumor was greater than that of the laparoscopic group(2.71 ± 1.13 cm vs 2.19 ± 1.30 cm,P<0.05),The average number of hospitalizations was less than that of laparoscopic group(13.68 ± 1.07 d vs 14.16 ± 1.12 d,P<0.05).Routine pathology showed no cancer cells in the distal margin of the tumor.The incidence of overall complication in the robotic group was similar to that in the laparoscopic group(10.14% vs 16.39%),and there was no significant difference(P=0.292).ConclusionRobots and laparoscopy can be successfully completed rectal cancer minimally invasive surgery.The operation time of the robotic group was slightly longer than that of the laparoscopic group,the robot group in the amount of bleeding,postoperative first exhaust time,catheter withdrawal time,the lower edge of the tumor from the far distance,hospital days have advantages.
