Palliation for Advanced Malignant Colorectal Obstruction by Self-Expanding Metallic Stents: Prospective Evaluation of Outcomes

Abstract

Self-expanding metallic stents are highly effective in relieving malignant colorectal obstruction. The complication rate is acceptable and palliation can be achieved in the majority of the patients without a stoma.

Stenting for colorectal cancer obstruction compared to surgery—a study of consecutive patients in a single institution

“…Despite these limitations, we believe it is possible to draw several conclusions from this study. Stenting of colonic obstruction in disseminated disease is uncontroversial [13,[25][26][27][28][29][30][31][32][33][34], as reflected also by the results of our study. The limited number of patients treated as bridge to surgery in our series reflects the uncertainty at our institution regarding potential tumour spread during stent placement [16], despite indications of the opposite in the literature [14,15,32].…”

Palliative stent implantation in the treatment of malignant colorectal obstruction

“…Other authors also have recommended this approach [3,28]. It is possible for SEMS implanted under different predictions to dislocate, as observed in four patients of our case series.…”

Large-diameter self-expanding metal stents appear to be safe and effective for malignant colonic obstruction with and without concurrent use of chemotherapy

“…It has been proposed that chemotherapy may increase SEMS migration risk, especially when there is evidence that it has induced tumor shrinkage [7,10,15,16]. Although the sample size in this subgroup was small (n = 10), we did not encounter any clinical stent migrations in this study.…”
