To compare the short-term prognosis of robotic surgery and laparoscopy for gynecological tumors through evaluating intra- and post-operative outcomes.

A retrospective analysis was performed on clinical data of 334 patients who underwent robotic surgery and laparoscopy in Gansu Provincial Hospital from Feb. 2014 to Oct. 2017, including 170 cases of robotic surgery (robotic), 164 cases of laparoscopic surgery (laparoscopic). Using t test, Wilcoxon rank-sum tests, χ² test, multivariable linear regression and multivariable logistics regression, analysis and comparison of operation evaluation indexes between two groups: operative time, the estimated blood loss, lymph node yields, postoperative abdominal drainage volume, length of hospital stay, postoperative complications and so on.

334 patients successfully completed the operation, and no major hemorrhage or other complications occurred in the two groups. There were 0 case and 4 cases convention to laparotomy in the robotic group and laparoscoic group respectively, but the difference was not statistically significant. The multivariable linear regression model showed that postoperative abdominal drainage volume was significantly less in robotic surgery (β=-237.62; 95%CI=-400.11, -75.13; P< 0.05), operative time (β=-7.65; 95%CI=-30.40, -15.10; P< 0.05) and length of hospital stay (β=-4.35; 95%CI=-6.69, -2.02; P< 0.001) were shorter, and lymph node yields were higher (β=7.41; 95%CI=5.24, 9.57; P< 0.001) than laparoscopy. However, no difference was observed between the two surgeries regarding the estimated blood loss (β=-31.25; 95%CI=-90.68, 28.17; P>0.05). The multivariable Logistic regression model showed that postoperative complication between two groups was not statistically significant (β=0.97; 95%CI=0.32, 2.95; P> 0.05).

Robotic surgery was more superior to conventional laparoscopy in perioperative effect for gynecologic diseases.
