Endometrial cancer is the most common gynecological malignancy, and most patients present at an earlystage. However, approximately 15% of confineduterus endometrial cancer patients will see their cancer return. Treatment options for recurrent endometrial cancer depend on the patient’s level of fitness, tumor dissemination and prior treatment. For localized resectable pelvic disease, salvage cytoreductive surgery may improve survival. Laterally extended endopelvic resection, enbloc resection of the pelvic tumor and sidewall structures, represents an option for salvage treatment in cases of isolated recurrence involving the pelvic side wall. 3 In this video we present a robotic combined laterally extended endopelvic resection and laterally extended pelvic resection for recurrent endometrial cancer. The patient was a 59yearold woman with a first endometrial cancer recurrence. The initial diagnosis was a welldifferentiated non myoinvasive endometrioid adenocarcinoma, staged with hysterectomy and bilateral salpingooophorectomy. The patient received no adjuvant treatment and 9 years later experienced the recurrence. No comorbidities were reported. Imaging showed an isolated lateral relapse in the right obturator fossa involving the ureter, obturator nerve, pelvic muscles, bones side wall and complete infiltration of the external iliac vein and internal iliac vascular compartment. After multidisciplinary tumor board discussion, we performed a roboticlaparoscopic assisted debulking, with enbloc resection of the external iliac vein, internal iliac
