Colonic stent insertion is useful for improving the quality of life of patients with malignant colorectal strictures. However, some patients have multiple strictures caused by direct invasion of malignant tumors arising in other organs or by peritoneal dissemination. Repeated sessions of stent placement can prolong the hospital stay or impair activities of daily living. We describe our experience with 2 patients in whom stents were concurrently placed in 2 stricture sites. First, a small-caliber scope was passed through the stricture in the distal colon, and a colonic stent was inserted into the stricture in the proximal colon by means of the Over-the-Wire (OTW) technique. Then another colonic stent was placed into the stricture site in the distal colon. Procedural accidents did not occur at the time of stent placement in either patient. The use of a small-caliber scope for stent placement in 2 sites is considered very useful in patients with multiple colorectal strictures.
