Abstract
We retrospectively analyzed the data of 12 consecutive patients treated with 18-mm-diameter Niti-S stents for obstructive colorectal cancer to determine the usefulness of these stents in colonic stenting as a bridge to surgery. The technical and clinical success rates were both 100%, and no procedure-related complications were noted. The technical and clinical success rates and rate of procedure-related complications using the 18-mm-diameter stent were not significantly different from those using the 22-mm-diameter stent in 21 cases in our hospital.
The Niti-S stent has good conformability. Intestinal tract burden is believed to be reduced with the 18-mm-diameter stent compared with the 22-mm-diameter stent because of low axial force, while usefulness was maintained.
