Comparative study of ICG and non-ICG-guided laparoscopic gastrectomy for gastric cancer: a propensity score-matched analysis at a single center.

Objectives: To investigate the effectiveness of indocyanine green (ICG) lymphography in improving lymph nodes (LNs) harvesting during laparoscopic radical distal gastrectomy for gastric cancer.

Design: Non-randomized trial, prospective study compared ICG and non-ICG group using 1:1 propensity score matching (PSM) method.

Setting: Preoperative clinical characteristics, operative outcomes, and follow-up results.
