Robotic surgery in endometrial cancer is a safe procedure in the class III and class IV obese patients.

We found low rates of major intra and postoperative complications, conversion rate and blood loss.

Oncological outcome seems favorable with a low recurrence rate.

AbstractObjective

Obesity has risen to affect >25% of the Canadian population. Perioperative challenges with increased morbidity are encountered. We evaluated the outcome of robotic-assisted surgery for endometrial cancer (EC) in obese patients.

Methods

We retrospectively reviewed all robotic surgeries performed for EC in women with BMI ≥40 kg/m2, from 2012 to 2020 in our center. Patients were divided into 2 groups (class III: 40-49 kg/m2, class IV: ≥50 kg/m2). Complications and outcome were compared.

Results

185 patients were included: 139 class III and 46 class IV. The main histology was endometrioid adenocarcinoma (70,5% of class III and 58,1% of class IV (p = 0,138)). The mean blood loss, overall sentinel node detection and median length of stay were similar in both groups. Six class III (4,3%) and 3 class IV (6,5%) patients required conversion to laparotomy due to poor surgical field exposure (p = 0,692). The rate of intraoperative complications was similar between the 2 groups (1.4% in class III vs none in class IV, p = 1). There were 10 class III (7,2%) and 10 class IV (21,7%) post-operative complications (p = 0.011), but most were grade 2 (3,6% in class III vs 13% in class IV, p = 0.029)). Grade 3 and 4 postoperative complications were low (2.7%) and not statistically different between the 2 groups. Readmission rate was low in both groups (4 in each group, p = 1.07). Recurrence occurred in 5,8% of class III and 4,3% of class IV patients (p = 1).

Conclusion

Robotic-assisted surgery for EC in class III and class IV obese patients is a safe and feasible procedure, with low complication rate, similar oncologic outcome, conversion rate, blood loss, readmission rate and length of hospital stay.
