Stent treatment for the benign or malignant colorectal obstruction / 介入放射学杂志

ABSTRACT

Objective To discuss the clinical efficacy of stent treatment for the benign or malignant colorectal obstruction. Methods Under fluoroscopic and / or endoscopic guidance stent implantation was performed in 30 patients with colonic or rectal obstruction. The obstruction sites were located at rectum (n = 20), recto-sigmoid juncture (n = 2), sigmoid colon (n = 3), descending colon (n = 3) and transverse colon (n = 2). Results Thirty-one colorectal stents were implanted in total 30 patients, the technical success rate was 92% by once-through operation. The patients were immediately relieved of the symptoms of intestinal obstruction. No complications related to stent implantation occurred. The average survival time in patients with malignant obstruction was 271 days. Conclusion For colorectal obstruction, stent implantation through anus is a minimally-invasive, safe and effective treatment with few complications. The procedure can effectively relieve the patients of the intestinal obstruction symptoms and, thus, improve their living quality.
