Abstract:
Objective To compare the effect of Da Vinci robot assisted and laparoscopic assisted radical resection of rectal cancer.
Methods The clinical data of 180 patients underwent Da Vinci robot assisted or laparoscopic assisted radical resection of rectal cancer were retrospectively analyzed. SPSS 22.0 software was used to perform 1 to 1 propensity score matching (PSM) for patients, and finally 51 cases with Da Vinci robot assisted radical resection of rectal cancer (Da Vinci robot group) and 51 cases with laparoscopic assisted radical resection of rectal cancer (laparoscopic group) were included in this study. The intraoperative and postoperative conditions were compared between the two groups, and the 2-year survival condition was analyzed in both groups.
Results The operation time of the Da Vinci robot group was significantly longer than that of the laparoscopy group, while the intraoperative blood loss, the C reactive protein within 24 hours after operation and the score of the Numeric Rating Scale in the Da Vinci robot group were significantly lower than those in the time of removing urinary catheter after operation was shorter than the laparoscopic group (P < 0.05). The incidence rates of postoperative complications were 13.73% in the Da Vinci robot group and 15.69% in the laparoscopic group, and there was no significant difference between two groups (P>0.05). The median survival time of the Da Vinci robot group and the laparoscopic group were 21.9 and 21.7 months respectively, and there was no significant difference between two groups (χ2=0.495, P=0.482). The 2-year survival rate of the Da Vinci robot group was 82.35% (42/51), which showed no significant difference when compared to 76.47% (39/51) of the laparoscopic group (χ2=0.540, P=0.463).
Conclusion Da Vinci robot assisted radical resection of rectal cancer can achieve the similar radical effect and long-term effect as laparoscopic assisted radical resection of rectal cancer, but the former is more conducive to reduce intraoperative blood loss, alleviate degrees of postoperative inflammation and pain, and promote the recovery of urinary function of patients.
