Metal Stents for Palliation of Rectal Carcinoma: a Preliminary Report on 12 Patients

Abstract

Stenting for rectal carcinoma is technically feasible and safe, and probably reduces the number of laser sessions required. However, better materials are required.

Clinical Application of Self-Expandable Metallic Stent for Treatment of Colorectal Obstruction Caused by Extrinsic Invasive Tumors

“…Generally, covered stents may be superior in preventing tumor growth in patients who require long-term colonic decompression but inferior in preventing stent migration because they are less embedded into the walls of the lumen compared with uncovered stents. 21,[27][28][29][30][31][32] Comparing the success rate of stenting and complications according to stent type (covered vs. uncovered) in our study, the technical success rate was higher with uncovered stents. However, two covered stents that failed technically developed from immediate stent migration and technical problems unrelated to the stent type.…”

Use of self-expanding metallic stents in the management of obstruction of the sigmoid colon.

“…Esophageal stents have a smaller diameter of 10â€"20 mm and are less flexible. These limitations may ex plain the greater incidence of stent migration and blockage in previous studies [2,5,7]. Pre dilatation of the stricture or laser therapy [2] may also prevent the stricture from gripping the stent,resulting in stentmigration.…”

“…They provide an altema tive to a colostomy for paffiating patients with obstructiondue to irresectable, locally recurrent colonic tumors [1][2][3][4], and they can relieve obstruction in patients with resectabletumors [5†"7]. The stents permit a planned, elective one-stage operation without the need for a tem poraiy stoma or for emergency surgery; more over,they may benefit elderly and frail patients with obstructing benign lesions [8].…”

Palliation of carcinoma of the rectum using the urologic resectoscope

“…Recently, encouraging results have been reported for the treatment of stenotic rectal carcinoma by endoscopic implantation of a prothesis [9,26,27]. In contrast to most endoscopic procedures, which require repeated treatment sessions after initial recanalization, rectal endoprothesis may prevent obstruction until death.…”
