Objective: The aim of this study was to clarify operative outcomes after laparoscopic surgery in patients with obesity diagnosed with early stage endometrial cancer.

Design: We retrospectively analyzed the medical records of 150 patients treated at our hospital between 2012 and 2016 to determine the prevalence of obesity and surgical outcomes. Patients were divided into the non-pelvic lymphadenectomy (PLN-) and pelvic lymphadenectomy (PLN+) groups. We compared surgical outcomes between patients with and without obesity in each group.

Results: We observed that 45 of the 150 patients were diagnosed with obesity (body mass index ≥25 kg/m²). No significant differences were observed in operative time, estimated blood loss, and duration of postoperative hospitalization between patients with and without obesity in the PLN- group. The operative time was longer (p=0.001) and the number of lymph nodes removed was higher (p=0.001) in patients with obesity in the PLN+ group. No significant differences were observed in estimated blood loss and the duration of postoperative hospitalization between patients with and without obesity in the PLN+ group. Intra- and postoperative complication rates were similar between patients with and without obesity (6.7% vs. 7.6%).

Conclusion: We conclude that laparoscopy can be safely performed for early stage endometrial cancer in patients with and without obesity.
