To investigate the feasibility and efficacy of Da Vinci robotic-assisted surgery in the early stage of ovarian cancer without inverted position. s A retrospective chart review of the patients with early stage ovarian cancer was performed in the First Affiliated Hospital of Zhengzhou University from October 2014 to October 2018. Patients with early stage ovarian cancer underwent robotic-assisted surgical staging: 26 patients underwent the inverted position approach (inverted group) and 32 received the non-inverted position approach (no-inverted group). The operation time, intraoperative bleeding volume, the number of lymph nodes resection, post-operative anal exhaust time, the average hospitalization days and complications between two groups were compared. s Surgeries were successfully performed between both groups. (1) The perioperative related indicators: the operation time and the postoperative anal exhaust time in the inverted group were significantly longer than those in the no-inverted group [(208±33) minutes vs (158±32) minutes, <0.01; (2.6±0.5) days vs (2.1±0.8) days, <0.01, respectively]. There were no significant differences (all >0.05) in the intraoperative bleeding volume, the average hospitalization days and the number of lymph nodes resection. (2) The comparison of the incidence of surgical complications: there were no significant difference (χ(2)=0.000, >0.05) in the rate of lymphatic retention cyst [4% (1/26), 6% (2/32)]. Da Vinci robot system without inverted position in omentectomy is safe and feasible. Compared to the inverted position approach, it also provides remarkable advantages, including reduced operative time and faster return of bowel movement, but its long-term effects remain to be followed-up.
