Trans-Umbilical Lymphadenectomy Using an Articulating Bipolar Vessel-Sealing Device (TULAB) during Robotic Surgery for Gastric Cancer: Enhancing the Surgeon's Eye for Reduced-Port Robotic Gastrectomy.

Despite use of fewer ports, RRDG with TULAB had similar outcomes to CLDG in terms of the incidence of postoperative morbidity and the number of harvested lymph nodes. Furthermore, by reducing the number of incisions, the incidence of the intra-abdominal adhesions can potentially be lowered when RRDG is used.
