Key clinical point: Carbon nanoparticle suspension lymphography-guided distal gastrectomy improves postoperative lymph node detection rate in patients with gastric cancer undergoing gastrectomy.
Major finding: A higher mean number of lymph nodes were detected with vs without carbon nanoparticle suspension injection (CNSI; 59.6 vs 30.0; P < .001). A higher number of lymph nodes were detected in black- vs nonblack-stained stations (9.2 vs 3.5 lymph nodes per station; P < .001).
Study details: This was a retrospective cohort study including 156 propensity score-matched patients with clinical T1-T4 gastric cancer who underwent laparoscopic or robotic distal gastrectomy with or without (conventional group) CNSI between May 2019 and December 2020.
Disclosures: This study was supported by the University Research Project of Hebei Province and the Medical Research Project of Hebei Province, China. The authors declared no conflicts of interest.
