Use of the Bard Memotherm self-expanding metal stent in the palliation of colonic obstruction

Abstract

In our experience, the Memotherm Colorectal SEMS was easy to use, was effective in the palliation of obstructing colorectal carcinoma, and appeared to reduce the risk of stent migration.

Self expanding wall stents in malignant colorectal cancer: is complete obstruction a contraindication to stent placement?

“…Technical success in this series of colorectal stenting was achieved in 89% of patients and is comparable with that of other studies [7,16–18]. The technical failures resulted from an inability to manoeuvre the guidewire past the irregular lumen of the obstructing lesion in two thirds of patients, with vascular catheter slippage accounting for the remainder.…”

Palliative stent implantation in the treatment of malignant colorectal obstruction

“…However, most references are related to carcinomas of the left hemicolon and small groups of patients [3,12,15,17,18,[20][21][22]. In addition, most patients in the reports underwent SEMS implantation before a definitive surgical treatment (''bridge to surgery'' concept) for acute colorectal obstruction [23][24][25], or there were mixed groups of patients [18,26,27], leading to only limited conclusions on the long-term effect of SEMS implantation as definitive palliative treatment for obstructing colorectal carcinoma.…”

Colonic Stent-Related Complications and Their Management

“…Several studies reported that the rate of stent migration is 4% to 10%. 5 , 15 , 23 This most frequently occurs within the first 24 hours; however, migration at 3 and 7 days after the procedure has been reported by Canon et al 21 Stent migration occurs because of technical factors such as inadequate expansion. In addition, the smaller the stent diameter, the more the colon is angulated; also, the more insufficient the length is to allow stent flaring, the easier could stent migration occur.…”
