[Two Cases of Chemotherapy after Self-Expandable Metallic Stent Placement for Obstructive Sigmoid Cancer with Unresectable Liver Metastasis].

ABSTRACT

Immediate decompression and induction of chemotherapy are exceedingly critical for obstructive colorectal cancer patients with unresectable liver metastasis. Systematic chemotherapy was administered after self-expandable metallic stent(SEMS) placement in 2 patients with obstructive sigmoid cancer with unresectable liver metastasis. Chemotherapy-induced tumor shrinkage led to SEMS migration, enabling the use of an anti-VEGF drug. Eventually, both patients underwent successful management without restenosis.
