The aim of this study was to report our single-center experience of the da Vinci robotic surgery system in the management of endometrial cancer (EC) patients during 2019-2023. We descriptively summarized the preoperative, intraoperative, and postoperative outcomes. Moreover, we conducted subgroup analyses based on obesity (BMI ≥ 30 kg/m2) and the intraoperative use of indocyanine green dye (ICG). Overall, 100 patients were analyzed. Eighty-five patients (85%) were obese. The mean operative time and estimated blood loss (EBL) were 240.84 ± 70.08 min (range: 110-720) and 104.2 ± 80.3 ml (range: 20-500), respectively.

The mean number of retrieved pelvic LNs was 3.01 ± 3.06 (range: 0-15). The use of ICG was employed in 58 (58%). Only a single patient (1%) underwent conversion to laparotomy. Besides, only three (3%) patients experienced vaginal laceration intraoperatively, respectively. The mean hospital stay was 1.34 ± 0.69 days (range: 1-5). No patient experienced postoperative complications. Most tumors had endometrioid histology (82%), grade-1 tumor (49%), and stage-1A disease (67%). At 3-year follow-up, only two patients (2%) developed recurrence.

Patients who received the ICG had significantly lower operative time (225.86 vs. 261.52 min, p = 0.011), estimated blood loss (90 vs. 123.81 ml, p = 0.037), and hospital stay (1.12 vs. 1.64 days, p < 0.001) compared with patients who did not receive it. However, there was no significant difference between both groups regarding the number of retrieved pelvic LNs. Obesity had no significant impact on the rates of intraoperative complications, postoperative complications, and 3-year recurrence incidence. In conclusion, robotic surgery was technically feasible and safe.

The use of ICG was statistically linked to favorable outcomes, in terms of decreased operative time, EBL, and hospital stay. Obesity did not impact the perioperative surgical outcomes.
