Robotic-assisted laparoscopic hysterectomy for endometrial hyperplasia or grade 1 endometrial adenocarcinoma: a ten-year, single centre experience.

Abstract Objective To describe the outcomes of patients undergoing robotic-assisted laparoscopic hysterectomy for grade-1 endometroid endometrial cancer or endometrial hyperplasia at our centre. Methods Retrospective chart review was completed for 160 patients who underwent robotic-assisted laparoscopic hysterectomy by 5 general gynaecologists in a tertiary care setting between September 2008 and September 2018. Outcomes collected included operative time, estimated blood loss, length of stay, perioperative complications, readmissions, and recurrences. Subgroup analysis was completed after stratifying by body mass index (BMI; 3 groups: A, 50 kg/m2). Subgroups were compared with ANOVA or Fisher exact test. Results The intraoperative complication rate was 3%. The rate of conversion to laparotomy was 2%, and the rate of bowel injury, 1%. The postoperative complication rate was 8%. The rate of major postoperative complications was 4%, and 3% of patients required readmission postoperatively. The mean BMI was 43 (range 21–71) kg/m2. There were no differences in perioperative complication, readmission, or recurrence rates between subgroups. Groups B and C were more likely to have had an ASA of 3–4, suggesting a higher burden of comorbidity. Operating room time, procedure time, and estimated blood loss were higher in group C. Conclusion Despite this cohort's mean BMI falling within the category of class III obesity, complication and conversion rates were similar to those reported in the literature and did not increase with BMI, despite an increased comorbidity burden. These results suggest that robotic surgery is a safe and effective method for providing minimally invasive surgery to a technically challenging population.
