    Abstract:
    STUDY OBJECTIVE: To describe the left lateral extraperitoneal approach to perform complete para-aortic and pelvic lymphadenectomy and transverse total hysterectomy from left to right as a novel approach to treat obese patients with endometrial cancer. Laparoscopic management of obese patients represents a challenge for the gynecologic surgeon. The extraperitoneal approach is technically easier in the obese patient because it naturally creates a bowel-free operative field. DESIGN: A prospective pilot bicentric and descriptive study (Canadian Task Force classification III) evaluating the feasibility and reproducibility of the transverse total hysterectomy and complete lymphadenectomy through left endoscopic extraperitoneal approach in obese patients with endometrial cancer. SETTING: A comprehensive cancer center in Toulouse and a teaching university hospital in Madrid. PATIENTS: Sixteen consecutive overweight or obese patients (body mass index > 25 kg/m2) with high-risk endometrial cancer. INTERVENTIONS: Currently, the left extraperitoneal approach is routinely used to perform complete para-aortic and pelvic lymphadenectomy. It provides direct access to the left ureter and uterine pedicle. This access can be extended to the right side when performing a transverse extrafascial hysterectomy from left to right. The procedure starts from the left extraperitoneal space, where the left uterine artery is sectioned and the vesicovaginal and rectovaginal septa are developed, without opening the peritoneum. Colpotomy is performed from the left to the right side. Once the right ureter is identified, the right uterine artery can be safely transected. Alternatively, the right uterine artery can be sealed and sectioned during the right pelvic lymphadenectomy. At the end of the procedure the peritoneum is opened to complete the surgery. MEASUREMENTS AND MAIN RESULTS: Between May 2015 and February 2016, 16 consecutive obese patients were successfully treated using this technique. Median patient age was 62 years (range, 44-78), and median body mass index was 32.5 kg/m2 (range, 26-42). In 3 cases the right uterine artery was sealed during the right pelvic lymphadenectomy, in 11 cases after completing vaginal opening, and in 2 cases after peritoneal opening. The median operative time was 137.5 minutes (range, 66-260). The median blood loss was 85 mL (range, 0-260), and no blood transfusion was required in any of our 16 patients. No significant complications occurred. CONCLUSION: The full extraperitoneal approach represents an interesting alternative strategy for the surgical treatment of obese patients with high-risk endometrial cancer.
