Core Tip

Core tip: The safety and oncologic efficacy of spleen-preserving splenic hilar lymphadenectomy (SPSHL) are being evaluated, but the data are limited, especially for robotic surgery. What’s more, few previous studies have compared robotic SPSHL (RSPSHL) with laparoscopic SPSHL (LSPSHL) for gastric cancer. Huang’s three-step maneuver constitutes a set of effective surgical procedures for the SPSHL, which was proposed previously by our department. Thus, we offer a single-institution investigation on the comparative safety, feasibility, and oncologic efficacy of robotic vs laparoscopic SPSHL. It is worth noting that this is the first study that compared RSPSHL and LSPSHL using Huang’s three-step maneuver for advanced gastric cancer.
