Insertion of a Stent in Obstructive Colon Cancer Can Induce a Metastatic Process in an Experimental Murine Model

Background Colonic self-expanding metallic stents (SEMS) are used in obstructive colorectal cancer patients as a bridge to surgery. However, its oncologic safety remains uncertain. Therefore, we attempted to clarify this further with an experimental study and constructed a mouse model of colonic cancer.
