To prove feasibility of laparoscopic and vaginal surgical approach in obese patients with endometrial cancer, 81 patients were included retrospectively in 2 Cancer Centres : 41 obese and 40 non obese. We performed hysterectomy with oophorectomy and pelvic lymphadenectomy by laparoscopic and vaginal approach. Operative time was higher for obese patients vs non obese (150 vs 121 minutes, p = 0.01) but pelvic nodes (16.3 vs 16.2), postoperative stay (3.8 [2-8] vs 3.6 days [2-7]), complications and disease-free survival (93 % vs 83 %) were similar. Matching 41 obese patients treated by laparoscopy with 29 obese patients with endometrial cancer treated by laparotomy, hospital stay was shorter in the laparoscopic group (3.8 [2-8] vs 7.4 days [5-10] p < 0.001) and pelvic nodes (16.3 [3-50] vs 11.5 [2-34]), operative time (149.9 [80-300] vs 167.9 minutes [60-390]) and disease-free survival (93 vs 80 %) were similar. One patient treated by laparotomy never received intended radiotherapy because of a delay greater than 3 months caused by cutaneous necrosis. For obese patients with stage I endometrial adenocarcinoma, laparoscopic approach should be first choice because of similar operative complications and pelvic nodes, shorter hospital stay and less abdominal wall morbidity associated with lower risk to delay adjuvant radiotherapy.
