Summary
Brief summary (as posted)
Colorectal cancer is the third most common cancer worldwide and results in 8-25% acute malignant bowel obstruction. Since Dohmoto et al. first applied and reported the self-expanding metal stents (SEMS) in the treatment of colorectal stenosis, they have been widely used not only as an alternative treatment as a bridge to surgery (BTS), but also as a mean of palliative option for stenosing lumen in clinical practice. Numerous publications have reported that the stent placement technique showed 75% to 100% technical success rates and 84% to 100% clinical success rates. However, it is sometimes difficult to place due to the distorted anatomy or acute angulations in patients and other conditions with poor endoscopic visualization with the normal colonoscope. The aims of this study were to present our results with two novel SEMS implantation techniques.

- Ultrafine Endoscope Assisted
- description
- The self-expanding metal stent (SEMS) implantation was conducted using an ultrafine endoscope (UFE) (GIF-XP260NS; Olympus, Tokyo, Japan). The UFE researched the stricture, and a guidewire was inserted into the endoscopic working channel. The guidewire was left. And the endoscope was withdrawn. The normal colonoscope was exchanged under the reverse guidance of the guidewire. Finally, a metal, uncovered SEMS was placed along the guidewire.
