Popis:	Placement of a self-expandable metallic stent (SEMS) is recognized as a safe and effective procedure for patients with malignant severe colonic stenosis. However, reports of this stent for right-sided colonic stenosis are limited, possibly as a result of technical difficulties. We report a new method for delivering SEMS to the site of right-sided colonic stenosis in four patients with malignant right-sided colonic stenosis. Technical success was obtained with sequential use of a double-balloon endoscope and ultrathin endoscope, while we also injected non-ionic contrast agent into the submucosal layer as a marker for stenting under fluoroscopy. There were no adverse events noted during the procedure and clinical improvement was seen in all four cases. In conclusion, SEMS placement for right-sided malignant colonic stenosis with our newly developed method appears to be safe and effective, and can be used for decompression of the right colon.
