Short-term efficacy of robotic and laparoscopic spleen-preserving splenic hilar lymphadenectomy via Huang's three-step maneuver for advanced upper gastric cancer: Results from a propensity score-matched study

Figure 1 Cost analysis between different groups and subgroups. RSPSHL: Robotic spleen-preserving splenic hilar lymphadenectomy; LSPSHL: Laparoscopic spleen-preserving splenic hilar lymphadenectomy; EG: Early group; LG: Late group.

Figure 2 Unadjusted (A) and adjusted (B) regression models of robotic surgery via Huang's three-step maneuver and complications. ¹Adjusted for: age, sex, body mass index, American Society of Anesthesiologists class, cT, cN, post-gastric artery, short gastric vessels, splenic upper pole artery, splenic lower pole artery, and the terminal branches of the splenic artery. BMI: Body mass index; ASA: American Society of Anesthesiologists; SGV: Short gastric vessel; PGA: Post-gastric artery; SUPA: Splenic upper pole artery; SLPA: Splenic lower pole artery; SpA: Splenic artery; SHDT: Splenic hilar dissection time; SHBL: Splenic hilar blood loss.
