Clinical Application of Self-Expanding Metal Stents in the Treatment of Obstructive Colorectal Cancer.

Objective: To investigate the safety and efficacy of self-expanding metal stent placement in treating obstructive colorectal cancer.

Methods: A retrospective analysis was conducted on 33 patients with self-expanding metal stents. The technical success rate, clinical success rate, and stent-related complications were observed.

Results: The success rate of self-expanding metal stent placement in this study was 100% (33/33), indicating that the procedure was technically successful in all cases. The clinical remission rate was 90.9% (30/33), indicating that the stent placement was effective in most cases in relieving obstructive colorectal cancer symptoms. However, the overall incidence of complications related to self-expanding metal stent placement was 12.1% (4/33), with stent displacement and detachment occurring in 3.0% (1/33) of cases each, and gastrointestinal perforation occurring in 6.1% (2/33) of cases.

Conclusion: These findings suggest that stent placement is safe and effective, but there is a risk of complications that should be considered. It can serve as a transitional treatment or relieve symptoms in advanced cancer and improve quality of life.
