Abstract
Purpose:This retrospective study was designed to assess the safety and effectiveness of open, laparoscopic, robotic colorectal cancer surgery.Methods:Three hundred patients with colorectal cancer who underwent curative resection in the First Affiliated Hospital of Zhengzhou University between February 2014 and May 2016 were included. Patients were classified into open surgery group, laparoscopic surgery group, and robot-assisted group.Results:The blood loss in laparoscopic surgery group was less than that in open surgery group, and the blood loss in robot-assisted group less was than the open surgery group. The number of lymph node dissection in robot-assisted group was significantly larger than that in the open group (P < .05). The distance between the lower edge of the tumor group and the distal margin in robotic group was longer than that of the laparoscopic surgery group and the open group (P < .05). Three (2.8%) cases of urinary retention occurred in the open surgery group, 4 (3.92%) cases in the laparoscopic surgery group, and 1 (1.1%) case in the robot-assisted group, while 2 (1.87%) cases of sexual dysfunction occurred in the open surgery group, 2 (1.96%) cases in the laparoscopic surgery group, and 1 (1.1%) case in the robot-assisted group. The urinary retention and sexual dysfunction rate did not differ between the 3 groups (P > .05), but the minimally invasive group showed a certain advantage over the open group.Conclusion:Compared to the traditional open surgery, minimally invasive surgery (especially in robot-assisted group) has advantages such as less intraoperative bleeding, rapid postoperative recovery, and radical cure; open group, laparoscopic surgery group, and robot-assisted group have a similar incidence of postoperative complications, but reduction in the incidence of anastomotic leakage and intestinal obstruction. Robot-assisted group has the potential advantage for pelvic autonomic nerve protection.
