Self‐expandable metallic stents (SEMS) have recently become widely used. A dedicated stent such as the through‐the‐scope (TTS) stent has enabled easier placement of SEMS by endoscopists for colorectal obstructions. In Japan, however, the TTS stent is not yet available. Therefore, we have to perform non‐TTS placement using esophageal, tracheal or vascular stents for colorectal obstructions. We have developed some modifications which aid the placement of esophageal stents, including increasing the length of the delivery system, and the use of a splinting tube or a double splinting tube. These technical modifications allow markedly better placement of a knitted nitinol Ultraflex esophageal stent for a colorectal obstruction. They allowed us to even place SEMS in the proximal colon without difficulty, and in all patients we treated. Therefore, with some technical modifications, it is feasible to use an esophageal stent for proximal colonic obstruction.
