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.
