SEMS: Self-expanding metal stents; BTS: Bridge to surgery; ASH: Abdominal surgery history; WBC: White blood cells; dNLR: Derived neutrophil–to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio; SII: Systemic immune inflammation index; LMR: Lymphocyte-to-monocyte ratio; Cross: Colorectal obstruction scoring system; LVI: Lymphovascular invasion. P < 0.05 was considered statistically significant.
