Para-aortic and Right Obturator Lymphadenectomy for Surgical Staging of Advanced Cervical Cancer through the TU-LESS Extraperitoneal Approach

Abstract

To present an innovative transumbilical laparoendoscopic single-site (TU-LESS) extraperitoneal approach for lymphadenectomy in a patient with advanced cervical carcinoma. Demonstration of the novel technique through video. In advanced cervical cancer, determining the status of the para-aortic lymph nodes is essential because extended-field radiologic therapy is recommended for a patient with positive para-aortic lymph nodes [1]. Nonetheless, the sensitivity and specificity of currently available imaging workup for positive lymph nodes are limited. Surgical staging enables precise evaluation. However, laparotomy has potential wound complications and leads to treatment delay. Multiport laparoscopic transperitoneal and extraperitoneal approaches limit surgeons' ability to reach the para-aortic area or obturator fossa in the same operation [2]. Thus, we take full use of these approaches' advantages and avoid their disadvantages to design a promising minimally invasive surgery approach [3]. Para-aortic and obturator lymphadenectomy through the TU-LESS extraperitoneal approach was successfully performed without complications. The patient recovered quickly and received subsequent concurrent chemoradiation on schedule. TU-LESS extraperitoneal para-aortic lymphadenectomy provides satisfactory exposure and easy access to both the para-aortic area and obturator fossa. In addition, the bowels are uplifted by an extraperitoneal air cushion to achieve excellent exposure and reduce the risk of bowel injury. With quick recovery, the patient could start accurate radiation treatment promptly.
