[Self-expanding metallic stent for unresectable obstructive colorectal cancer].

Colon stent self-expanding metallic stents(SEMS) are useful for obstructive colorectal cancers (CRC). SEMS placement has indicated in the palliation of malignant colorectal obstruc- tion, and bridge to elective surgery for resectable colorectal cancers. SEMS can reduce the risk of early complications, mortality, stoma creation rate, and shorten hospital stay. Although SEMS placement was associated with a risk of perforation of the colon and late complications, it also contributed significantly to better long-term quality of life. Perforation might occur with mishandling of guide wire during endoscopic procedure. Therefore, it is better to take careful attention and follow the mini-guide line of Japan colonic stent safe procedure research group during the procedure. SEMS could provide feasible outcomes for patients with obstructive unresectable CRC as palliative treatment.
